My mechanic used to run the service dept. at a ford dealer. I have a 2000 Excursion V-10. 1. Go only to dealer to purchase new spark plugs every 80k miles, replace all 10 coil rubber boots and clean inside of throttle body. 2. If you have after market off-set rims, change out front hubs every 60k miles. 3. If you experience "theft light" issues and it won't start at turn of key, the diodes in the alternator may have failed, causing all kinds of problems with your PCM. It will continue to charge battery when running but will discharge when not running. Replace with remanufactured ford alternator. 4. If someone steals your cat-converter and damages the wires to your 02 sensors (before and after the cat-converter) it might cause the number 19 fuse (under the hood, 20 amp) to blow and render the engine limp-mode. I experienced all of this and the only real problem was the Alternator went out...big deal...took 45 mins to replace. The other stuff was caused by outside forces.

Got a 2000 400k Miles doesn’t miss a step and most times is pulling a 4500lb lawn care trailer or my 5000lb boat! Either way 11mpg loaded and 14.5mpg unloaded. Coils are super common on these too, along with everything you stated. But really even with all these things the cost of ownership is still cheaper than most Volkswagens !!!!!

:41 I'm gonna stop you right there . . . The 6.8 Does NOT require premium fuel. If you reed the manual closely, it says if in your climate/altitude you experience knock, to use premium. I've put around 3500 gallons of 87 octane through these engines, and they run just fine.

Good video. I believe the 6.8L V10 is recommended for 87 octane fuel or higher. 93 octane isn't required. Coils are another common issue also.

Thanks for the video. I have a 2002 e350 6.8ltr van I work/ live out of. I've blown out 3 plugs on original engine. First time was a huge surprise. Very loud! I did research and bought the "time sert" retread insert kit. Did the repair with engine in van. Very difficult, lack of space. Extremely nerve racking. Drilling a big hole in the head is something that is not natural. Anyway, worked excellent. Had the pcv cracked hose up under throttle body as well. gave intermediate rough running. Would have never found it if someone hadn't suggested looking. Almost impossible to see on my vehicle. Engine made it to 300,000 miles then developed miked oil and gas somewhere other than in the cylinder....automatic transmission made 240,000. Just installed a rebuilt high performance engine and getting ready to fire it up. I love these engines, and love my van. Mileage is 10mpg no matter what I'm doing... yup that sucks. cheers

I have a 99 F250 extended cab lariat with a V10 automatic with factory 4:30 gears. I have owned this truck for 17 years and it presently has 172,000 miles. In all this time, I had one spark plug blowout (#2) and I repaired it with a Time Sert Kit myself. I did not trust anyone with this procedure. It’s been seven years and still running great! She is 24 years old now and I have replaced the PCV-short U hose three times,fan belt once, two alternators, ten OEM injectors, ten OEM coil packs and ten OEM plugs. I keep her serviced every 2500 miles because that’s all I drive it in a years time. There are no oil leaks, no exhaust leaks at this time. She has been a good truck for a first year Superduty. I still pull my fifth wheel camper from time to time with no issues. This time next year I will be applying for an antique tag! LOL!

Good job it's great to educate folks about problems that mechanics encounter on what folks think should be a simple job. Now maybe as they learn they will understand why their automotive bills cost what they cost. They can learn things that will save them money and it's a great feeling to fix something yourself!!

I’ve owned several v 10 never had a plug problem. Only problem is 7 mpg pulling 10 empty.

Holy cow Love this video and thanks for making me feel better about buying my new used truck for 6,800$ with less then 130k and dropping 3,300$ back into to it in order to get the helio coil fixed because of the miss firing issue and needing to replace the coil packs on to cylinders with the tune up and well now have it chipped for better gas mileage and it seems to be working as far as getting better gas mileage for a work truck. Its a 1999 but I have been looking into the spark plug blowouts and that was one of my biggest concerns about getting to the truck but holy cow its a beast of a truck this is the biggest truck I have owned in my life and its like driving a whale in a kitty pool!

A mechanic telling you the 6.8 requires premium fuel isn't much of a mechanic.

Great and well explained work!

My 99 F350 Owner's manual says to use Regular 87 octane fuel and I haven't had any problems using regular fuel. Not sure why Premium was said to be required.

Great videos. Bought a New Holland service truck. 2003 F250 v10. 320K. Sold my 2014 ram for 30K. This truck I just bought is also "damage title" I found out after dealer sold it to me for $2700. It had perfect fluid and runs too good to be true. Looks like they did lots of service to it.

Awesome video, the first two problems are ones I've already encountered and dealt with on my 2000, definitely a great truck.

Thanks for the great informative videos. Hope you guys do one on a 1996 F150. Thanks

Great video man! Thank you :)

Great Content! Thankyou!

Bought a ‘99 from a buddy. F350, flatbed, new trans, new brakes, new coils, new Cooper tires… the list goes on and on. They got tired of putting money into it, so I picked it up for 1500. I’ve put a few hundred into it, but at 250k on the clock, this thing is a dream. HOWEVER, it makes a weird shrieking noise occasionally, hit a bump, noise starts, hit another bump, noise stops. What in thee heck!? I’m stumped.

Good video explained well

great vid, perfect

Oh snap🤯 now I know why I'm losing power and a pop sound with truck just running in park. Spark plugs could be bad, I need to check right now. Need my truck for winter,, thanks a bunch for the tips on major issues with this Ford truck.

Thank for the info,I recently had a clutch replaced in mine new everything,it seems they didn't live the throughout bearing properly I scoped it and its dry shouldn't you grease all fork contact point so it will not vibrate and make noise while clutch pedal it out 2003 model

A couple things I noticed that you discussed in the video that aren't correct. I'm not trying to nitpick but just want the correct info to be out there as others are watching. 1. The generation that you are working with (the 2003 model) is the 1st generation or commonly known as the "2-valve" version which was offered from 1999 to 2004. ** (NOT up to 2007 as you said in the video) ** 2. This version did NOT have 360 horsepower as you mentioned at the beginning of the video. The 1st generation 2-valve versions of the Ford V10 for the Super Duty had 310 HP and 425 lb-ft. torque respectively. The 2nd generation (more commonly known as the "3-valve" versions) from 2005 to 2010 in the Super Duty trucks had 362 HP and 457 lb.-ft. of torque. These engines were offered in other vehicles with different power ratings as well such as Uhaul box trucks, RVs, buses, stripped chassis trucks, and other vehicles. In many cases, they had different intake and head designs and some parts are interchangeable between the different engines and some are not. But that's a different discussion. For the 1999 to 2004 versions for pickups, they had the option of the 4R100 or 4-speed automatic transmission or the 6-speed manual. From 2005 to 2010, they updated the automatic to a 5R110 or 5-speed and still offered the 6-speed manual as an option. They don't offer the 6R140 or 6-speed automatic transmission for the Super Duty pickups from 2011 and newer however, they do offer this with the chassis versions such as Uhauls, buses, RVs, and other models. To my knowledge, there is no conversion kit avialable to mate the 6-speed automatic to the 6.8 V10 for pickups. So, one would need to get this from a donor vehicle of one of the vehicles mentioned above. 3. You called the valve cover a "valve cap". I've never heard anyone refer to the valve covers as valve "caps" ever. I'm sure it was just a simple mistake and I'm not trying to get on you about it but it was just odd. -------- This channel's videos are great and this one is as well for the most part so please don't take my criticism the wrong way. I would suggest just doing a simple Google search in the future when discussing particular models and engines so you have the right info. If you need to, just use a 3x5 index card to have a few notes on and refer to that. This doesn't need to be so professional that you can't use a simple index card. ---------- For the Ford V-10 engines, although you did mention a few issues that they share with the other similar 4.6 and 5.4 V-8 models such as the spark plugs blowing out on earlier models and the exhaust manifolds bolts rusting out, you didn't mention one very important difference about these engines in relation to some of the newer 5.4 engines. The fact that both versions of the 6.8 V-10 DO NOT HAVE camshaft phasers or usually known as VVT (variable valve timing). This makes this engine so much more reliable with less moving parts internally to break down. That might be one of the main reasons that these engines have been so reliable and I think it's something that is worth pointing out. If you read the various forums and other sites online or in Facebook groups, you'll notice many owners getting at least 200k and 300k and more out of these engines before they have a major breakdown. Usually. So, they are pretty reliable for a lot of miles with little money invested. And, they are a lot cheaper to maintain than diesel engines with only needing 6 quarts of oil with a filter compared to at least 14 quarts or more with a diesel. One of the main downfalls (other than what you pointed out) is that they typically don't get the best fuel mileage. Usually. Most owners report getting between 12 mpg and 13 mpg unloaded (without towing a trailer) driving down the highway. Many have said they get between 7 mpg and 9 mpg when towing a trailer. But in fairness, it's all relative to how you drive. My guess is that "most" owners of these V10 pickups are spending more time on the gas than they need to because they like to have more "fun" in the seat of their pants due to the power. So, if they would just be "nicer" to the gas, most owners would probably get an extra mile or 2 better. Personally, I own a 2002 F-250 extended cab 4x4 with 8 foot bed and with the 6.8 V-10 and 4-speed automatic with 3.73 gears. It's got 308,000 miles and runs pretty well. I get between 14 and 16 mpg if I'm driving conservative at around 68 to 73 mph with little to no wind against me on the sides or front. If I want to do 75 to 80 mph, that obviously goes down to around 11.5 to 13 mpg. But wind is probably the biggest factor in how good or bad the fuel mileage will be. Even if it's from the side, it's still not good. I use an old Superchips Cortex 2950 tuner and have it set to the "fuel mileage XS" tune to try to get the best fuel economy and run the cheapest 10% ethanol (87 octane) whenever possible. Sometimes, I'll get an 88 octane that I think is a 12% to 15% blend (I might be wrong on that) from a local Casey's general convenience store that is a few cents cheaper. But usually, I just put the cheapest stuff in I can wherever I'm fueling up. I also tow with this setting without issues and have towed over 20,000 pounds (total with truck, trailer, cargo, fuel, me, tools, and etc.) and it pulled fine so I just leave it on the fuel mileage XS setting. I've tested it with different fuel and the tow setting and performance setting and overall, the fuel mileage didn't improve over the same conditions and terrain so I decided the added costs for fuel wasn't worth it.

You guys are the best 👌

I think the nausea from the exhaust is caused by the huge repair bill. Wouldn't you think the maker could have used stainless steel bolts, especially considering the vehicle cost.

Great education.

I’d say the blowout problem is still present on newer engines, just less common. I don’t own a 6.8, but I do have a 2009 Crown Victoria with the 4.6. It blew a plug a few weeks ago. Easy to fix, just pricy. Not a bad guide for people wanting to buy one of these trying to find what can fail on them. Tritons are solid motors with a few flaws like any decent engine.

Did any of the 6.8 v10s have the same 2 piece spark plugs like the 5.4 triton? If so what years have them and which ones do not? Thinking about purchasing one and would rather not get into the headache of having the 2 piece plugs snap off in the heads. It would be a huge help. Thanks!

I have a 99 F350 with the V10 Triton. Bought with blown engine, did an engine swap with a used one. It runs great with excellent compression and oil pressure but have an issue with fumes in the cabin. To me it seem more like gas fumes than exhaust. Have checked all vacuum lines for deterioration, no leaks that I can detect. Is not coming from the emissions cannister output and there are no gas leaks anywhere in the engine compartment or in the fuel lines to the tank. It is enough to get a bit of a headache when sitting still or moving slow - during normal driving, can't really smell them. Ran fine without any codes this summer for about 700 miles but then threw a DTC P1131. I cleared it but came back within 25 miles. IDS shows: HO2S11 not switching correctly. Sensor indicates lean. Air leaks at the exhaust manifold (I replaced all the broken studs and installed new exhaust gaskets on the replacement engine). Freeze frame shows SFT1 and SFT2 at -3.91% and LFT1 and LFT2 at 10.94% but not sure if that is normal. Not sure if the fumes and the DTC are related - any ideas? Not sure what to look for.

I was watching at 2x speed guy is still very helpful but funny. I learned very fast. Thanks for putting video out you helped out a lot of people with the info.

Thank you!! My issue has been simple and every mechanic has avoided even talking about it! Manifold bolts🙄 The rest the truck is damn near new with new transmission and entire front end. Been widling away at the engine trying to find the issue.. no codes for months yet loss of power and that dumb tick. .

I am looking to buy a 2000 f250 v10, this video is helpful.

Excelente

Thank you so much buddy Mike Ford V10 has a 114,000 miles on it and it had a tune-up at 100,000 miles with spark plugs do I have anything to worry about you think

Awesome video! I got an EX 6.8 and have a tap I could not figure out until this video. I changed the sparks fuel injector coils and nothing. Thanks for your help!

Just wondering if you have any information I have a 1999 250 with the V10 and trying to pull a camper just does not seem to have the power I thought it would have what would I need to check

If you own a Triton Two Valve engine buy the CalVan insert kit and proactively install all of them. Do it when you plan on changing plugs and oil since that is part of the job. Costs a few hundred but you don't want to blow out a spark plug out on the road.

Bad ass lots to know thanks.

Love you Lenny! Great video..... your friend kippa boy

Thanks for the video, great info! How much of it applies to a 2008 Triton V8? And do you have a similar video for that year? Mine is in a motor home and I keep getting a check engine light for the fuel rail pressure out of range.

Thank you , great video Now I know what that taping noise is haha .I thought it was a lifter... thanks again

I like this guy.

It would be nice to see a video on the grounds

Actually an exhaust leak can cause an O2 sensor code/codes and really screw up the fuel trim. It can also burn up an exhaust valve, I wouldn't say you can drive it like that long term with no issue..

I LOVE YOU 1A VIDEOS!! I just ran into in issue i cant figure out. i have a 2002 ford V10. it was parked for about a month, when i started the truck it had high idle and it would not drop to normal idle. while driving it stays high idle and i have to press hard on the brakes to keep it from moving forward. I cleaned out the throttle body, changed the air filter, TPS, used carb cleaner and sprayed the entire engine to see if i find a vacuum leak, and still no luck! engine starts up and revs upto 2500 -3000 rpms and stays there. Any advise as to what is my problem? I'm all ears! TIA

Do you have a video regarding the coils related to the spark plugs?

I have a ticking sound most noticeable when cold in my 03 Ford Explorer 4.0 and now I’m thinking it’s the exhaust somewhere near the headers

Thank you for this video I have always had Jeeps and now looking at a 2007 f250 6.8 v10 king ranch and didn’t even realize what gas it too I thought reg was fine but now I’ll have more questions for the seller

Hi great videos as always. Do you guys sell or rent the tool so we can drill them straight. If not that could be a great way to bring in extra money, get the tool,parts,drill bits,good gaskets, manifold etc… I would purchase or rent it from you…

How is the transmission on the 2002 of that model and is the 2002 included in the spark plug problems? Helpful video thank you.

I said to myself, Triton? If the first thing they talk about isn't spark plugs flying out of the heads like fireworks ... U did good, guys 😎

Know anything about tuning or performance chips?

Hello I’m having a problem with my 2001 f250 super duty XLT V10 triton, check engine light comes on with code PO720… “output shaft speed sensor” it’s not causing a lot of trouble just a kick in gear from 1 to 2. I’ve replaced the sensors both, transmission fluid as well. The light still will not go away. Do you have any suggestions?

Can you do a video about push rods & lifters?

It explains some of the complaints I have heard about these trucks. It would be kind if you could give and estimated cost to fix these different problems. I think I understand the complaint, now, of the aluminum shavings getting into the oil and destroying the engine. I have heard complaints of these spark plug repairs that only lead to that. Not pretty.

I have a 2003 f250 super duty 6.8l v10 that stalls occasionally but starts right up again after turning the switch off for 30 seconds or so. I've replaced multiple sensors, the fuel filter and relay, and cleaned all connections but the issue remains. If you have any ideas for resolving this issue of stalling I would greatly appreciate your feed back. I can drive the truck 4-5 days without a single stall, then out of the blue she stalls. Most offen it stalls under power but has done so at idle 3 times. Can you help?

Hello. Great video. I have an 03 f250 with the 5.4 and 86,000 miles that runs great until it rains or gets washed 🤔. After that, it has a slight skip when idling and while driving, it doesn't accelerate well because of a skip or misfire. If you really step on the gas however, you eventually get pass the skip, but acceleration is still terrible. Again, this ONLY happens after a heavy rain or a car wash(hood closed and no engine cleaning is done during washes). After about a day, everything is fine again...

I have 380k on my 2005 v10 excursion it’s been great. I’ve had to have the studs fixed 7 times tho but I’m a pro at it now

Question about pcv valve… I’ve had diesels but I’m looking at buying one of these v10s in a excursion. Pcv sounds a lot like egr on a diesel? Is it something people delete? Or is it not similar at all. Thanks

I have a 99 f53 with a 36’ holiday rambler on it, I realize it’s very heavy but it very gutless, it almost seems like its not getting full throttle. The person I got it from had Banks put long tube headers on and a transmission thing that plugs into the transmission, I also think it has tune plugged into it, any ideas? Thanks, Jerry

My 2000 f350 had the plugs blow out like u said.number 5 and 3. But I have multiple missfires that I can correct

I hope you do a video about how to diagnose problems with this motor with an obd2 scanner

what does fuel pump whine sound like (on a dying fuel pump)? 2000 Ford Excursion V10 limited

Nice , question? Is this the same v10 that's found in the RV motor home's,?

Make sure you use motor craft spark plugs. I manage a fleet, and 2 2013 f450 v10s I have had champion plugs in them from before I joined. These plugs deteriorated in under 30k miles and the ceramic insulator on the plug fell off and destroyed multiple cylinders.

I have a 2000 Rv with the v10 in it traveling at 40 miles per hour flat no issues. When I start to climb or pull my car losses power. Suggestions. Only have 55,000. Miles on the engine?

Starting issue lately. I have a 99 F350 V10 service truck. lately You have to trying to start it 4 or 5 times before it actually starts. It seems to run fine but its bad if you have to sit there and try to fire it 5 times. Common? What is the common issue? Thank You Jim Hughes.

Hi buddy I got the same truck but 2000… It really is a very reliable, resistant and durable vehicle. I have traveled all over the country with it, I have pulled heavy trailers and it has never let me down, the spark plug thing is true, it has done it 2 times after 10 years with it... but I have now a P1633 what should I do? thank you

Had an 03 xlt never missed a step 600 thousand plus. It took a front end collision to take it out. I have an 04 now king ranch same v10. 200+ O'Rileys said I needed new alternator my mechanic said alternator is fine. Cold weather came I need to jump it in the morning. Sometimes I have to hold key for 30 seconds before the starter engages. Anyone have anything they can share where I should go next. I bought new battery going in.

I ran a lot of different Triton motors never put premium gas they run on 87 just fine!!! I've operated 15+ 4.6l V8 2v 15+ 5.4l 2v and 10+ 5.4l 3v 10+ 6.8l V10 2v and 15+ 6.8l V10 3v Over 500,000 miles of driving with 87 octane I've tried 93 octane not worth spending $$$

I have a 2002 E350 6.8 V10 with 244000 miles on it. I'm confused because I keep hearing "before 2002" and "after 2002" with regard to the spark plug thread problem. Did Ford correct this problem with 2002 models, or did the fix begin with 2003 models?

Hello congratulations you for the channel I have an excursion 6.8 V10 I feel very well despite some problems .. when I accelerate I feel vibrations with a whistle .. do you think it could be the PCV valve? Or could it be some problem with the transmission? Thank you very much for your help Marcelo from Italy do you speak Spanish maybe?

My 2001 is hard crank sometimes in the morning and lately hard to crank during the day if it has been sitting also I get a code for too lean system bank 1 and 2 but no other codes just wondering what the fix may be.

I was looking to buy a 2002 f 250 with a v10. Would a compression test help diagnose if there is a problem with the cylinders?

2003 6.8L F350. Pings with 93 octane. Idle is Very smooth. No engine light. It will ping at cold or at operating temperature. Hauling a load or empty. Should I start with replacing the PCV valve and hose then work up to the Mass air flow sensor? It does seem to have power, but I have to ease the throttle when accelerating. 1/3 throttle at most.

Just bought a 1998 F-250 5.4 triton I don’t hear or see vacuums leaks but when trying to accelerate it bogs down does not want to pick up speed it does the opposite but I can hear the fuel pump turn and truck turns on fast but last owner had gas sitting for 8 months can that be the reason why it ain’t running properly also I get a code po171 , what can that be?

Hello, Im having the same problem.with my truck. I want to know if you will hurt you truck if you drive your truck like that for a while and if so what would happen.

I have a friend with a 2007 crew cab and it lost power while towing a camper over the hills and when you start it up you can definitely hear an irregular erratic firing that sounds like a valve issue on the passenger side. I need to remove the valve cover there and inspect the cam and rockers. At the tail pipe you can feel that there is an erratic pulse of exhaust. Do I need to jack up the cab to get to this? Is there something else that I could be having an issue with?

You solved most of my problems but should I check each spark plug or is there a way to find out which spark plug is misfiring? I don't have the computer?!

Great info and question I have a V10 , 1999 , 115k miles .. Engine seems strong , when idling, as of lately when driving down road at any speed seems line it is missing and I hear noise like pressure blow by and truck seems there is a disconnect between engine and transmission any ideas to me I thinks it's a sensor not picking up the rpm acceleration or foot pedal gas increase and then timming is off ?? What do you think

Would be cool if you did a video about the the intigrated relay panel for the fuel pump and related components. Cost me $1300 in St George Utah to have the Ford integrated relay bypassed so that I could get home. Now I'm having trouble with the other integrated components on the same panel. Would be a great video to see what's involved with just replacing the whole panel instead of waiting for each relay to fail.

Harmonic balancer on these tritions like to dry rot and separate. They will start to squeak when they go bad.

I have a 2000 Excursion 6.8 V10. I replaced all of the exhaust manifold studs due to the problem mentioned in this video. (took me a month) working on it when I had time. I bought this Monster om 2013 with 90K on it. It now has 140 K on it, 8 inch lift with 37 inch tires:-). I just ccompleted rebuilding the complete frontend minus the diff which was fine. Today I have a cranking situation with no Start. I am assuming its the fusebox in the occupants compartment. I have power at the injectors. No spark at the plugs. I have a couple relays to swap out before I dump the cash into the fuse box. The other thing I ran across is my scan tool won't complete the scan....a problem solving I go I guess.....

what octain of gas should I be putting in my 2008 Ford F350 6.8L V10?

So I just picked up a F250 SD, I wish i would have seen your video first. :) but my ? is, what's the odds of my mechanic checking theses type of things on a "reg" check and service? should I ask them to look for theses thing specifically. ?

Bet you haven't seen this one: 2001 F250 6.8; at 87K miles got #6 misfire, pulled coil and had 1" coolant on the boot. never water on top or even rain. Sucked it out with straw and shopvac, drove another 80K miles rinse and repeat. Otherwise best truck ever, no, best vehicle ever. Work truck, airlifts for heavy loads, then snow plowed 5 years, followed by 30' 5th wheel coast to coast 10 times. Now 175K and had to replace fuel pump, otherwise virtually no expenses but tires. Terrific truck. But coolant into #6??

I have a 1999. It cranks but won’t turn over. Is it a fuel pump or spark problem. I’d there any test I can do to find out what the issue is. It is cold here. High in the 30s during the day. Obviously much lower at night, in case that might also be an issue.

Great video they seem to be helpful. I have a 02 excursion V 10 the other day it lost all power brand new battery no lights dash lights or fire to the starter. Not sure what’s going on battery no more than two months old has anyone ever experienced this actually, the battery is about four months old. Thanks in advance for any input.

drivers side exhaust manifold has 4 broken studs. i dread this removal. i get lots of codes for misfires. ive changed 3 coil packs and now im doing 3 more but im heading out to check that PCV hose right now ;) i have a 2000 and as far as i know there isnt any issues with blow out. when i do my plugs, i always start the truck for under a min when cold. i assume warming the block just slightly , helps. redone the entire front end and may need new steering gear. nothing cheep on this truck ty4urvid

4:21pm eastern. So I am troubleshooting an f350sd 2003 flat bed which cranks but doesn’t start. I sprayed a bit of fuel into the air intake throat valves and it started right up, shutting off as soon as it used up what was sprayed. I pulled the hose off from the filter below the driver side frame and cranked the engine, no fuel. I also don’t hear any pump noises from the tank. Could it be the tank fuel pump?

How much does it usually cost to replace those exhaust manifold studs in a 2001 lariatt v10

i have a 1999 f250 super duty v10 and at cold start it runs great soon as it warms up it starts acting up sputtering idle just keeps going up and down soon as u step on gas it goes away I've changed the pcv hose and map sensor cleaned throttle body still runs bad any clue as to what's going on plugs and coils were done last year along with water pump fan clutch radiator alternator air filter all new

Torque spec for the spark plugs on 2004?

Great info, I have the 2000 excursion v10 limited 4x4. I'm getting 8 mpg. Just replaced pcv hose, had shop do the plugs. Next in line is banks headers because exhaust manifold leaking. $2000 for the banks set up. I need to improve the 8mpg issue or I will let it sit and by a 45 mpg car. What can I do to get better gas mileage ? I dont put my foot in it, I take it easy and still no improvement. I wish they had a turbo to go with this v10. Mpg is what I need help with. I'd be happy with 12mpg.

if you still monitor this channel, Driving down the freeway at 55, all of a sudden a large popping noise was coming from the right side of the engine compartment. Almost like a massive exhaust leak somewhere. Ford had told me that one of the rockers fell off and the head was damaged. They said they were able to repair the head and The rocker for a very substantial cost. The vehicle never lost power but just a very loud popping noise. Any suggestions on what that could have been?

Is there a vac hose diagram and a hose diagram for the 6.8 2002

Need to make video about removing oil pan and gasket.

I've seen the plug go right through the head. You should mention how this applies to the 5.4 and 4.6 2v. As well as the breaking plug issues.

I have an 02 excursion 6.8 I pull a roll off dumpster set up with it works great but I do get exaust fuels inside. Still haven't figured it out. The only other issue us the driverside front break always grabs first even after replacing all brake components. I also have an 01 f250 that pulls a 16ft enclosed trailer for vending no issues at all with it. Both are below 130k miles.
