My new '95 XJ12 Jag has a major problem! What did the CAR WIZARD find that halted a simple tune up? 

having owned multiple Jags in my life - anyone who buys a v-12 Jag deserves all the entertainment that they can harvest

Power ratchet to remove plugs? Wow, I have a serious issue with that. I've even seen guys install plugs with a power ratchet, which is nuts. Remove and install plugs by hand, please. That way, you can feel what's going on. Put a light coat of grease on the threads of that spark plug tap, before you run it in. It'll prevent bits of metal from dropping into the combustion chamber. Swapping out that V-12 for a Chevy 327 V-8, is a common fix for all the complications which crop up in those fussy V-12's.

I've enjoyed your program for at least two years now and I really appreciate what you have taught all of your subscribers. I have learnedto be patient with the shop that services our car, thanks to your thorough explanation of all the problems that repair-facilities face.

I can't understand why so many ppl love these cars! I was an automotive machinist in Toronto Ontario during this period of jaguar "engineering" and every time we spoke to Jag mechanics they would regail us with tales of torture working on these! I was lucky enough to never have to do any re and re's! BUT my gawd! just rebuilding these POS' was a challenge! "pinning" the hardened steel lifter buckets because they came loose and smashed the cam, dealing with the 3 stage (different threads) studs that hold in the cams,l you name it! these cars are great if you love wrenching! lol

Mrs. Wizard isn't the only one who is a teacher. Great explaination of the problem(s). All the best for the New Year!

Your honesty is great, 50% of your viewers are hooked on that. The other 50% we are watching the diagnosis and repair, sure that must include all that comes with it, the Good the Bad and the Ugly. Always tell it like it is and be worry free. Thank you

The x308's have a trick to get to that rear spring pan stuff without risking your digits. If I remember right it goes like this: -Remove calipers and wheel speed sensor harness, and hang on body somewhere (bump stop?) -Slightly preload lower wishbone with a jack -Undo 4x nuts that hold upper spring pan to frame -Remove shock lower eyelet bolt -Remove preload on lower wishbone, allow it to drop -Rotate halfshafts so that the U-joints allow for the most flex At this point you should be able to pull the vertical link down enough that you can pull out the upper pan, spring, shock all together out of one side. You might need to undo the rear truss to let the A-frame pull away from the frame a bit for that extra clearance. That's how I did my shocks+bushings job, never needed to touch a spring compressor, and relatively low risk. Not sure if the x300's have changes in the design which prevent this trick from working. That center support bearing (again this is x308 experience speaking) isn't sold by Jag parts shops or dealers, as far as I remember, but you can buy the bearing direct from manufacturer. Powertrain industries 3080-25 (again that's if the x300 uses the same driveshaft, I know it's similar but maybe not identical)

Coming across these unforeseen issues is such a bummer. The other day we replacing the t-belt and water pump in out Camry, which you have been a relatively easy job until we found the crank bolt wasn’t budging. In the end, just removing that bolt took longer than the book time to complete the hole job.

I would recommend ordering your parts from Denooyer Jaguar in Kalamazoo, MI. The parts professionals there have decades of experience with Jags and other British vehicles. Hell, one person there actually worked in an MG parts department in the late 70's. Not only are they a Jaguar dealership, they are also an importer of parts for classic Jags, MGs, Austin Healey, and Triumphs, under the name Engel Imports. I used to work there over a decade ago. All of the same parts professionals from then are still there.

How right you are about old cars and hidden problems. After 24 years of driving the same car there was a bridged fuse in the fuse panel that could have burn't this car to the ground and it was a one owner car that when bargaining the price the owner took my first offer what a nice surprise and now the reason is apparent. Just glad that I lead a charmed life !

You may have missed the underlying cause of the stripped spark plug. These heads have recessed spark plugs which collect sand, grit and oil. When the plugs are removed the grit falls into the plug hole. Then, when the new plugs are installed the threads are destroyed. Everything is OK until the next mechanic comes along and removes the spark plug. It is vitally important to blow off any debris before removal and carefully clean the spark plug seat before reinstalling. As far as the spring mounts are concerned, you may have replaced them the hard way. For many models it is straightforward to put the car on a lift and lower the entire rear suspension assembly onto drums as a single unit. Then, they are very easy to work on. Hope this helps.

Oh so true, Weeezard .... I've tried to tell friends many times that (1) you don't want an older car with ultra low mileage and (2) you want to drive any vehicle you own at least once a month for 20-30 minutes to keep everything working as intended. I'm glad to see another seasoned mechanic with good common sense.

Jags from this era are 100% worth fixing when done correctly, like anything in life, "look after it and it will look after you" I have one of the last 2009 XJ x358 and had it for some years now, absolutely no intention of changing it any time soon, it simply dives as elegant as it looks....Love It.....

Helpful tip! On the spark plug tap, when i used mine, i load it up with grease in grooves to catch the metal shavings and crud, keeps it from falling into the cylinder

We had a 95 Jaguar XJS convertible that had something that could only be described as a wiggle at higher speeds. It was this way from new and the dealer tried everything to fix it including changing the wheels and tires. They finally diagnosed that it had a warped drive line. After that, it was fine. We had the car 14 years and it was high maintenance, but overall very reliable.

I bought an XJS V12 and it had a misfire. After waiting until it was dark in the evening I opened the bonnet and saw what looked like the aurora borealis jumping around from the ignition leads. New leads were ordered and fitted. No misfire anymore

The Jag content on RU-vid is rich right now. Between you and the XJ12, drivetribe’s pair, auto Alex and his, I’m here for it.

Happy New Year to Car Wizard & Ms. Wizard! Looking forward to continued great content in 2023! Jag V12's can be a PITA to access sparkplugs! I also sympathize with the infamous "we can order it for you" phrase dealing with auto parts vendors, can sometimes take weeks instead of days. Firing order is 1A, 6B, 5A, 2B, 3A, 4B, 6A, 1B, 2A, 5B, 4A, 3B. Barrel of fun! I like our '52 Jag XK120 w/3.4L inline 6, plugs are all right on top and can be changed in about 15 min. Thanks for a cool video!

Nice cars when they run. Encountered one of 'em with the V12 in a parking lot in Lincoln Park in Chicago back in the 80s. The hood was up, a guy was standing next to it with tears streaming down his face. Knew a mechanic back then who worked on 'em, "Two and a half hours to pull one spark plug."

A transmission filter change can also turn into a much longer job when the previous well meaning person torques the pan bolts to OEM specifications, but the OEM specifications are for a perfectly clean, dry, tapped hole. Unfortunately, most people don't clean out transmission pan mounting holes with brake cleaner and compressed air before torquing the pan screws, so they almost always over torque them. A bent pan or stripped hole are the result. Fortunately, it's easy to fix, and the well meaning previous "mechanic" should be commended for caring enough to change the transmission filter. Over torquing is a very common issue with valve covers as well.

As a Jag tech I would strongly advise you have those Fuel Injectors checked for spray pattern and operation - Ultrasonic cleaning is my preferred method also renew the "O" rings to ensure you don't have air leaks into the inlet manifolds. PS Fuel additive is not thorough enough to clean this type of injector.

love the round headlight jags, such a pretty car! i hope it treats you well edit: a lesson on older cars, i have not owned a car that i didnt build or rebuild from an empty shell, so i know all of the secrets of the car. my favorite was sadly taken from me by a red light runner, but that car was completely fresh top to bottom, just waiting on paint (that i still have). started in -30F temps, handled snow and ice, great mileage, and my wife and kids loved cruising in it. and it was from 1987. if you know where the secrets can hide, you can enjoy beautiful older cars with all that character.

I think I'd like to see some video of how rethreading spark plugs works. For some reason I can just imagine bits of metal from the hole landing on the piston and causing problems later on. Maybe just using a broken head on the workbench :)

I bet that Jag looks beautiful in the sunlight ! 😊 always been my dream color combo & model of Jag on my wish car list

Wizard , the reason for the plugs in the centre of the engine is because it is a "Heron" head engine, with the combustion chambers in the heads of the piston rather than the cylinder heads. To get effective combustion, the spark needs to be quite central in relation to the Heron recess in the piston.

Car Wizard's new hobby will be constantly trying to fix that Jag.

How do you stop swarf from the re-tapping from getting into the cylinder?

I used to work on those VJ12 and XJS 20 years ago. I still have my 94 XJ12 I used to daily back then. I know how much you're enjoying it. Seeing you work on your beauty reminds me of doing all those jobs on customers' and my cars. Thanks for the great videos!!

This is a GREAT lesson to learn, especially for backyard mechanics like me. I’m glad you’re showing the hard stuff that you’re going to run into. Happy New Year to you and Mrs. Wizard!

Mr Wizard is correct! Ahh, the young fast mechanic, air impact and ram em in. Fast Fast Fast! , gets you the paycheck. I always hand screw in plugs, with at little silver anti-seize on the 3rd thread up from the bottom. I repair all my cars, never bring them into a “Shop” for maintenance. But i did get tires once on my pick-up truck. Three weeks later, I had to put my 4’ snap on floor jack handle on a 3/4 drive breaker bar and jump on it to break the lugs loose. Next time I’ll buy a tire machine. Love your videos, I have a V12 XJS.

I’m very excited to see the video about the driveshaft bearing. I believe my -95 XJ6 X300 has the same issue. It’s gonna be very helpful to see the repairs.

Around last year I purchased a 2000 Lexus RX300 SUV for my girlfriend for 2 grand, in coincidentally the same hunter green color as your new Jag. We got it at 219,000 miles BUT, I knew after looking it over quickly that it was not a rust filled piece of junk and it’s a Toyota so I trusted it to work as a daily driver. When we got it the only things it needed were new rear struts and new tires all around. Today it has just shy of 232,000 miles on it and the only thing really wrong with it is it will burn maybe a quart of oil every month or so, so I’ll top it off every month to keep it in check. That’s just from poor maintenance in its past but really with 232,000 miles on it it’s not a big deal. We’re just going to continue using it until it can’t run anymore. The proof is in the pudding guys. When the car wizard suggests buying a Toyota product for the best reliability, he means it. It’s not because he gets a cut from Toyota to promote their cars. Their cars are actually just that good. Not without fault because they will have problems, but compared to other makes they have proven to be the most reliable! Thanks Car Wizard for all you do for us and the content you provide on your channel. Happy New Years to both you and Mrs. Wizard🎉

Jags have loads of that "finger shashing work". Worked at a small euro only garage in high school in the 90s; my boss charged 50% more to work on them because he hated how poorly they were designed and built.

Keep hammering home that message that stuff happens with cars. I have good relationships with the shops and mechanics we use because I know how little things can completely derail what looks like a simple job. I once picked up a van I used to own after a service, drove around the corner and lost power and a colossal misfire made itself known. I stopped and could see what the issue was when I did some basic checks. Both the oil and the coolant had turned into a milkshake. I continued around the block and back into the mechanics bay and said, "I think the head gasket has blown, is it OK to leave it here until you can find a spot to look at it and replace it and I'll get the train home?" They were dumbfounded that I wasn't screaming and ranting that they'd broken my car. It was just one of those things. We had a good chat about looking for other potential issues with the coolant system and engine block and at 3pm the next day they rang me to pick the car up and they charged me for the parts only, as it was such a simple job and I hadn't been a dick. I made sure that their Friday night beer fridge was in good order.

I felt like a novice the first time I realized one at a time was the best way to do plug wires, glad to hear that it’s the way you do them and that is the easy way therefore the best way

I found your channel today. I am a nurse practitioner…not mechanically inclined. My beloved ‘99 daily driver XJ8 VDP has not started since 26 Dec, and I am holding my breath, hoping she can be repaired. Appreciate your channel and agree that newer cars are not as stylish. Enjoy your new Jaguar.

I love those 6.0 V12s. Did plugs and wires on many V12s. I found taking the compressor off the 5.3 V12s made it safer to do the front two. Also, that single wiper is awful. I was happy to sell my 97 VDP with the single wiper. Finally, did many rear shocks on them. Very difficult job. Patience is necessary. Well Done Wizard!

My favorite surprise was 20 years ago I got a hold of a one owner 40000 mile Dodge Dart Swinger loaded, 318, front discs, factory AC, vinyl top, beautiful untouched little old ladymobile, but it needed valve cover gaskets and the driver side valve cover had THREE cross-threaded bolts from the factory and the passenger side had one.. Mopar quality....

Nice start to the ownership haha. When I worked for Jaguar, we found lots of people also made problems for themselves by using non-genuine parts. We'd have a car come in and get moaned at that we were asking to replace something the owner had got some other garage to replace 6 months earlier. It amazed me how some folk couldn't understand that the part generally costs more because it's better quality, not because of the fancy box it comes in.

There's a guy in Norway who makes complete aftermarket injection systems for the Jaguar V12 as well as a bunch of other goodies. Mobeck Tekniske, for anyone interested.

I learned the hard way about changing spark plugs that hadn’t been changed in a long time in aluminum heads. I cross threaded the passenger rear spark plug hole and had to buy a thread chaser to clean up the mess. Also found that vacuuming out the metal shavings in the repaired spark plug hole makes inserting a new plug much easier. Continue to enjoy the channel with all the different vehicles that get worked on, plus seeing The Wizards professionalism and also supply problems that plague automotive shops today.

Dave you can look back on those first few years with Tyler in your little garage workshop, and how you've progressed. We look forward to see how much Tyler will be spending with you over the next 52 weeks..

Happy New Year to all the car guys and gals, and to the @ Car Wizard . Watching these videos are entertaining, informative, and remind me why I don’t own a Jag or other European cars lol. Beautiful looking cars though!

it's so cute that the two of these luv birds run this channel. Happy New Year 🎉

This is why you go by book time not what it takes you time - most of the time you faster than book time

Those jags are some of the most beautiful cars ever made and that v12 makes them even sweeter.

Beautiful Jag - they are classy and timeless unlike so many luxury cars. It’s worth sorting these problems as will have a wonderful car to show for it. Great video Wizard. All the best to you both and the family for 2023

Thank you for such great insight as always. I replaced the plugs and packs on my 2007 boxster. No real issues but it is time consuming and having never done that before, it’s all new to me. But having patience and the right parts and tools helped me to keep the frustration to a minimum.

before we had everything on computers a spare parts sales guy usually knew more about your car than you did. They could often recommend alternatives if the part you wanted was unavailable. Now people just trust what the computer says and as the old saying goes 'garbage in- garbage out'. the worst things are when changes are made mid model. One of my friends experienced this with her Nissan Micra. We ordered new from suspension parts but found they were totally different to what was on the car. Hers was later than the parts supplied. They got exchanged Ok but it meant she didn't have her car for Christmas.

On Jaguars the bolts for the drive line flex coupling if removed have to be put back in the same spot when reassembled. Jaguar uses bolts with different weights for balancing at the factory. So over the years if a mechanic worked on the drive line and didn't put the bolts back into the same holes, it could cause drive line vibration. Don't ask me how I know. 🥴

The only reason I'd buy this year of a Jag is to get one with the straight six. When I was a kid we had a brand new '89 XJS with the V12; one that a local dealer gave to my family on a trade in '87 Sovereign that also junk from the factory (if I recall; there was a part in the motor that required a machine to remove of which there was only one in the country so it was not feasible to do within a reasonable time.. at least the dealer did something though.. imagine going through this today with a new car, you'd likely be stuck with it!). The XJS ended up with the fuel injector problems, naturally; as well as other issues over the years. As a new car the XJS broke down on a road trip and the motor had to be removed just to replace a power steering line!? At the same time back in the day we had an '87 Cadillac with the 4.1 which had less problems and was therefore more often used as a daily driver; now THAT is saying something!

Back in 1984, at 21 years old, I bought an S2 Daimler Double Six, last of the carb V12’s, it took me 2 hours to change out its plugs, the 2 at the firewall end had never been changed as they’re awkward to get at, I managed that without stripping the threads, and replaced the diaphragms in the stromberg cabs, changed out the thermostats, changed the oil, etc; but as a novice back then I took better care of it than Jaguar technicians evidently did, it came with a full JSH, and it had only ever been half done, but when I finished and spent a couple of days on it, it became a 2 ton flying machine! At that time, there wasn’t a faster car on the road, it whipped 323i BMW’s, wiped the floor with Mercedes, Audi’s, you name it, it whipped it! It did the 150mph they said it would, it got to 60 in around 5 seconds, that’s a 1974 British sedan! Only downside was it eventually shredded its torque converter and an engine out job to replace it, which I did, but one very underrated sleeper, it’s old 5.3 was bulletproof, one very fast magic carpet ride, it guzzled fuel at 8-10mpg, but who cares, finished in BRG with doeskin interior, mint, chrome factory steels with hubcaps, it was a peach! Wish I still had it now, it loved the red line and I wasn’t scared to drive it hard, what a lot of car then for less than £1000!! 300hp on tap! It met its demise when some drunk idiot drove into the side of it parked up, tore the side out of it, wrecked it, lucky the impact put him in hospital....!

I love your honesty, things are not always easy. Keep up the good work.

Which is why I like copper anti-seize on my plug threads.

These old jags are so nice looking, but holy smokes are they high maintenance.

I bought a xjs that had a pickup coil issue. I got that fixed and went for a test drive. It blew a plug out about 5 minutes in. Somebody had JB Welded the plug in. I had to get in there and Helicoil It. V-12s are a little more Labor Intensive requiring some wobbles, adaptors and some disassembly to change all the plugs.

Levelled, it looks even better now. So much for the story I heard about removing the guards to change plugs on the V12! Best wishes for the year ahead at Omega.

I knew exactly what that sag was about! I had to do the same on my x308. Great to not sound like there was a dead body in the trunk anymore... Edit: I did it in under an hour with no spring compressors... just loosened under the diff, disconnected the bottom of the shock and used a scissor jack to push the control arm down.

Jaguars are the best. I grew up with Jaguars. My father had a 1987 Jag XJ6, a 1989 XJS , a 1998 XJ8 and a 2001 S-type. i had a 2002 X-type, 2005 X-Type,and a 2003Stype R . Your XJ 12 is perfect. Very beautiful.

As a shade tree mechanic, I've always thought it was strange the plug wires and spark plugs were next to a hot exhaust pipe. Now my F250 has them on top and centered. Maybe Jaguar was ahead of the curve.

Another great video Wizard! Too bad about the wires and plug, but you don't allow these things to get to you. Blessings to you, your family and your team for a safe, happy and prosperous New Year!

Just this week for the first time I was tuning a small Honda engine and when I went to put the spark plug back in I cross threaded the head. I learned about the thread chaser. It works so well. I have new confidence in my mechanical skills. Wizard you need to do a video to show home mechanics how to use a thread chaser. Thank you.

Welcome to the world of Jaguar, especially something considered "vintage". While a lot of stuff is out there with time, you will run into the NLA parts (as I'm sure you know) and when nothing used is any better than what you have, its time to get really creative. Great looking car BTW...super jealous.

I love wizards video because they explain everything so well and the wizards voice is so calm and relaxed. keep it up !!!!!

Did a transfer case oil replacement on my 2007 rx350 that I got a year before in great condition, the person who did the job before rounded the drain port. $70 worth of tools and parts and one sacrificial Walmart ratchet wrench later the job was finally done.

Agree reference parts - my 2007 Merc CL500 is having a holiday at a workshop for 3 weeks waiting on a rear brake caliper. None in Australia, minimum 10 working days from Singapore. With Christmas and New Year that’s likely to be mid Jan….

I love that you now show the actual work. With real problems

Those wires looked like they belonged to an 1995 xjs v12.

That is a lovely car you have there! I am English but no live in France! I had an uncle that had exactly the same Jag but a 1960's one and that was so silky smooth! I can understand why you Brough it! I know you do not need me telling you this but I say it, in the sprit of kindness! Good Luck with it all! Oh yes! I wish you and your dear wife and your guys at the Shop! I wish you all, a Happy and Prosperous new Year! 🤩🥳😉😜

I bought a low miles 03 Grand Marquis. In under a year it's needed brake rotors and pads, front struts, rear air ride conversion (to coil springs), and a transmission fluid/filter change. The tires were 8 years old and NOW the intake manifold gasket has a leak. The last item is the signal to upgrade the coils, replace the plugs and wires as well as upgrade to a performance intake manifold. Even a legendary car with a good powertrain is going to require the deferred maintenance to be caught up.

Have been in a similar situation, drilled a hole down centre of tap to blow compress air through as I turn it while piston at TDC with valves closed so swarf is blown out of tap releafs , happy new year , keep up the good work

My husband had to replace the top rear shock isolators on our 1995 X300 4.0 Sport as they had completely disintergrated resulting in loud bangs whenever we hit a bump. It took him one day to do one side & half a day to do the other side as he learnt a few tricks doing the first side. He didn't compress the spring. He lowered the rear sub-frame. He replaced the shocks while he was doing the job as he did not want to have to do the same work in a year or two to replace the shocks.

In Jaguar nomenclature the area between the two heads is known as the valley of death. It should be entered cautiously with magnetic pickup tools and inspection mirrors. The 6.0L with coil packs were much easier than the older dual teir distributor setup. Even still we used to use what's called a may head spark plug socket. It's kind of a crows foot spark plug socket. Be grateful you have one of the V12s with modern wiring. The old ones would get brittle and crack if you bent them too much. I'm a former factory trained Jaguar tech. Really enjoy going down memory lane with these videos. My favorite x300 sedan is the 96 xj12. The acceleration of the V12 needs to be experienced, you don't realize how much vibration you feel with the V8. It's incredible how smooth they are, occasionally they would lose six cylinders because of ignition problems and all the customers would notice was that they were lacking power.

Thanks for the great video, Wizard. I work on PC's but I'm very meticulous just like you are. I take pictures, I draw diagrams, and don't unscrew or unplug anything unless I know why. If I'm pulling a broken part out, and I have to disconnect, unplug, or change something that I don't want to, I'll take out some snips and cut it or something so I can get it out.

My dad had an 87 vandenplass - it was a beautiful car. When he died we took it to a garage to have it restored. They called us to tell us the transmission failed. When we got there I couldn’t help but notice the rubber donut marks all over their parking lot, and the fact that the tires had been shredded right down to the cords. We ended up getting a bill for $3200 and having to pay to tow the car to a junkyard. Didn’t fight it since it all happened right after the funeral and mom was upset, but four years later, I’m still not very happy about it.

When the first 5.3L Jaguar V12s came out in the early '70s, some genius engineer decided to put the ignition coil in the V. A few thousands of miles later the engine ran poorly because the coil overheated. I use e3 plugs in my AJ6 engine (AJ= Advanced Jaguar) without any problem. Just installed the 2nd set a few months ago. 10 min. job. (159k on the clock). I also did the rear insulator job but I made the isolators on the top of the shocks out of polyurethane.

As you know, we all love the videos with u wrenching, it teaches us alot, I have 93 xjs convertable, 12 cylinder, I love it except the inboard rear brakes

I have a 92 XJS Face lift coupe and most fuel related parts for that MY are mislabeled by so-called Jag expert shops. Somehow in their parts world for a V12 stops to exist somewhere in the Lucas area. It's been difficult to source the right parts for anything newer than 1991 since Jaguar has mad a lot of parts changes over the remaining years of the classic Jag 6s and V12s. Any Ford owner should be familiar with this type of business.

Either you have the patience of a saint or a great editor to edit out the colorful vocabulary. Love the informative real world videos.

I worked on the straight 6 and V12 jags years back, good luck, wait until the coolant level drops, and or, the intake temp sensor goes, and raw fuel starts pouring out of the tail pipe.

The rare bread of an honest mechanic! At larger European cars nothing goes smoothly!

So right about ultra-low mileage cars. You want a car that's been driven. Cars that have been barely used have a lot of issues that will crop up due to neglect and simply lack of maintenance.

Good news, Rockauto has those wires on wholesale for $3.55, wild! Then a range of choices from $37-45 per set. From the pics they appear to be correct for coil packs too. Nice looking ride!

This Cross-threaded Plug is one reason that I always start everything that has threads with my fingers-hand tightened them first before using a electric wrench that most mechanics use these days and Do Not Over-Tighten...

Happy New Year, Wizard & Mrs Wizard, may you both have a happy, healthy, and prosperous 2023! Thanks for all the great videos! 🖖🙏🇨🇦

The look of disappointment is real Car wizard. That rethread tool is amazing. I know the feeling with hidden secrets I'm a mechanic as well and the day is 5 minutes away from blowing out

“Cream puff car”. I had an 03 XJ8 with 110,000 on it. I loved it. Thought it would be worth giving the attention it needed. Problem was, it never stopped needing attention. Similar to yours, it started with the strut mounts being replaced in the front. It went downhill from there. MAF sensor, fuel level sending unit, vacuum leaks, etc. I gave up. I hope you get her to run flawlessly and she stays running flawlessly. Mine was a money pit.

you pull the plug out and you put the plug in do the sparky parky, turn the plugs round and round, that's what it's all about I lost my 91 G20 to someone before me. They changed the thermostat and no anti-sieze or anything, so when I went to change it, a bolt twisted off. I had a second 5.7 TBI engine on a pallet so I thought it would be easier to change the intake out than drill out the bolts under the cowl. Yeah, no. They must have had the intake off, for some reason it was painted black, and the two front bolts also twisted right off. At which point I had a van I couldn't even drive to the garage as the intake was loose. In 2021 I got my current 94 G20 with 47,000 miles on it. It weeps some oil out of the front of the engine but in 6000 or so miles no puddles, no major leaks. Knock on rust.

Wizard, how do you prevent metal shards from dropping into the cylinder when tapping the spark plug hole???

Happy new year, wizard! Beautiful jag. Many happy motoring miles and easy fixes for you in 2023.

Are those 2 pins or 3 pins coils? What is the designation on the coils? I wonder what the similarity between the 6.0 Jag V12 and the Aston Martin V12?

The very last 6.0 v12’s had the zytek ignition coils which is what you have. Those leads you had were probably for the earlier Marelli on the earlier 6.0’s which were different again to the HE’s and pre HE’s

Obviously someone was ham fisted installing the last set of plugs. Such a inconvenience when you discover these problems. Love your channel and insight to automotive repair.

I know on Srettin's M539 channel had a simillar issue on his e31 850 with a spark plug thread that was literally pulled and had to tap in larger threads and put a sleeve so that the plug can be torqued in the head.

Had the spring isolator cups smashed on my Thunderbird, replaced with urethane

Boy, did that cross-threaded spark plug bring back memories! I am 73 and back in 1966, I decided to change the spark plugs on my first Jaguar XK-120. I got the plugs out with no problem. BUT I cross-threaded one of the replacements into that aluminum head! I thought I destroyed the engine. Fortunately, the foreign car service shop where I worked after school as a parts chaser, repaired the problem with a Helicoil. I still remember that moment! I also remember that 120 took 11 or 12 quarts of oil!

Happy New Year to you and yours, Wizard. Nice hand model work, Mrs. Wizard 😉It's not just things automotive that one finds 'surprises' like than. Home repairs can hide interesting surprises of their own.

at 08:20 - "you won't even have to think about the firing order, it's a non-starter..." Good one!

Thanks so much Mr. And Mrs Wizard 🧙‍♂️ for making these great videos. Looking forward to the next one on the Jaguar and of course any other vehicle. Y,all take care and may the Lord bless you.

I made the plug wire mistake when I was 18yrs old. First and last time I did that.
