Afraid I rented the proper removal tools from the Jaguar Enthusiasts Club here in the UK. It cost me £75, but that was better then struggling for hours!
Hi! Will you give me advice please. I have an little oil leak from under the timing chain cover (AJ34S). Mechanic says to replace timing chain cover gasket. For this action do I need to take out the engine? And do I need to disconnect the supercharger?
There is no need to remove the cams under spring pressure. Once the chains are off, just rotate the cams to the "safe position" where all valves are closed.
@dalehuxford4522 My LR3 2006 4.4 with beloved 207k miles on it succumbed to not having good working water pump. I wasn't there when my wife said it "steamed" and smoked a lot. But it started up fine to get it 400 yard to the drive way. Having never seen a blow head gasket nor comprehending the savage outcome, I replaced the water pump, belts and thermostat and housing, but of course got quite a surprise after doing all that work to see that there was some steam blowing out off the left front bank of cylinders and seemed to idle slightly rough. That's when I realized oh, all that steam for a good while my wife said must have been the head gasket. It's been an amazing vehicle we have had for 14 years, and it was running so strong and beautifully. I cried. She didn't go very far on it, and it had the best synt oils, but I worry none the less that this might have done something worse. Suggestions? Thank you sir.
Sorry, hadn't seen this query! I would take the heads off by and see if they're straight or not. You may find a light skim and new gaskets and oil and all is well again. Or, when you get the head off, you might see issues in the bores. Then you have to start making bigger decisions!
Would never happen if you owned a Japanese vehicle...especially at 50k miles....those engines are just breaking in at 50k and coming to the end of the life on a JLR motor...
For an instructional video you really should use some sound and speaking instead of leaving it up to the viewer to interpret what you do just on video. Seems kinda lazy to me. Why didn't you even make a part 2 video?
Thank you so much! This is exactly what I needed right now. I am removing the head(s) on my 2002 XK8 to find the cause of zero compression on #5 cylinder. I know I am way over my head on this, but I hate to junk the car.
Did you use the tool to put all four CAMS back perfectly? I'm over complicating this I think. But I have to remove heads and don't know how to put the CAMS back properly.
This video is way more popular than I thought it would be. This is to back up the ebay sale I have running at the moment, feel free to look here if you want to see the auction: ebay.us/SjH3AP
Hey I have one of these. I emptied the gas tank and cleaned the lines. Anything else I could check before trying to turn her on. When I first got the generator I tried starting and after a dozen pulls it fired up for a few seconds. Any ideas?
@@jamespurdy405 I'd suggest it could be the auto-oil level inhibitor or, simply rubbish from dried fuel in the floatbowl. I've seen float needles gummed up on our generators that we use for annual events. We now empty float bowls and check flow of fresh fuel if it's more than 6 months between uses. The ethanol fuel isn't the best when left for long periods of time.
Afraid not. It's taking ages to do and I ran out of time and energy. The day job just keeps getting in the way. However, thanks for the prompt, I might try and get it back on the list of things to do. Ta.
He left the exhaust manifold attached to the cylinder head. He disconnected the three bolts from the exhaust manifold to the catalytic converter. This makes it much easier to access the bolts attaching the manifold to the cylinder head when it's out of the car and easily a accessible.
Nice video. Small note: VVT is only relevant on 4.0L engines; 3.2L engines have no VVT. Also, AJ27 has different VVT gear - not interchangeable with AJ26. Finally, the chains and tensioner kits are also different between AJ26 and AJ27 for these and other reasons. Great video and work dude.
Hello, are the head bolt nuts 13mm? I have a struggle with one bolt. The nut is going over. It is probably corroded as there is a water leak, probably in that area. I wont loosen the others further, as the head could warp. need help.
This doesn't sound like fun. I can't remember the bolt head size, but unless you've already done it I would buy one of those sockets that work against the flat walls of the bolt head hexagon rather than the points. A 12 point socket is going to just round off the bolt completely. If that doesn't work, you're going to have to very carefully drill the head of the bolt off and hope to pull the head off the bolt. However, there's not enough space in the car to do it, so you'd have to pull the engine out. Ouch. It's usually at this point that I would make another coffee, take a piece of cake, and just stare at the job for a while, waiting for inspiration. If no inspiration arrives, leave it well alone for a couple of days!
It wasnt turning over. It is 13mm. It just sounded like going over and the 13mm nut was just looking used inside, which made me think its going over. I was very causious and turned only little by little and it calways made a clunking like sound. replaced the 13mm by polydrive. thanks anyway.
It would be great if you split it up! All information gratefully received. Do you remember how how you kept the crank in the correct position? Did you Tippex/mark it or did you use some sort of tool to hold it in place?
I've started editing the rebuild video, but it's quite a lot longer, as it includes all the clean-up of the valves, tappet clearances and the slow job of re-torquing everything. I will get it finished. Maybe I'll split it into some smaller videos that might make it easier...
You may have a point there, I can turn a spanner, but think I'm a bit rubbish when it comes to creating and adding a script, so I added the words to the screen. Maybe I'll try adding my voice to the next one...
Hey Dale.. I have a 2000 Jag S-Type 4.0 V8 my tensioner broke on the passenger side and the cam timing chain broke..i see some oil in the spark plug holes.. can you give me a suggestive overview of what issue is in front of me and what I precautions I need to take.. thanks for the video upload it was very helpful.
you aren't fixing that. When the tensioner breaks and it shears the timing chain, that causes the piston to smash into the half open valve. Your head is destroyed, and you aren't replacing that for any reasonable sum of money. The cost to fix it is more than the price of a comparable jaguar. Ditch the car. It's not worth it.
