XK8 Ignition Coils Replacement Turns Into Valve Cover Reseal 

Glad to help.

Welcome!

Cool, thanks.

Glad it helped. No problems so far.

This is the best description that I have found. Be sure to confirm your production date and engine is original not swapped. www.jaguarforums.com/forum/xk8-xkr-x100-17/cylinder-numbers-system-191533/

Thanks

Defiantly get your hand on a manual is always the best thing. Even your best professionals will use the manual. Next is yes, check the valve (cam) covers for warpage. Some is ok and can be solved with proper sealants (RTV, etc.). Never pull your covers while the engine is warm this can cause warpage. Always fallow torque specs. Also be sure to keep your open engine covered so debris doesn't get in. Once again the manual is your best friend. Just make sure it is for your year, make and model. Best of luck.

@@weekendwarriorgarage4402 Thanks! As I started to take the air intake off I ran my finger inside the ends of the breather tube and there was oil. What does this mean?

@@ambrosemartos6408 how did you sort the oil in intake? i have that too and it dirtied maf sensor and needed to clean it. i think i have leaky valve cover gaskets likewiseb

Holding great. But do change the seals if they are old. They can start splitting and the silicon will be useless there.

K will give it a try, I did end up changing the seals and was still getting oil. thank you 😊 🙏

Sorry for the delay. I used the TRQ brand from Amazon. They came in a set of 8 coils and rubber plug connector PN: ‎ICA61610. They where about $150.00 for the set. I have had them in over two years and no issues. They also have a Life Time Warranty part only.

Possibly not sure how well they would hold up after absorbing the oil or how cost effective they are.

No, it's what was on the car when I got it. Waiting on Moss or some one else will start making replacements.

@@weekendwarriorgarage4402 Some on mine are cracked too, will need to fix or replace some how.

Not sure there the only difference I found was a few have a threaded end on top as well for mounting other items in place (hose retainer ect.) Possibly different year different setup? Thanks for info. Something to watch for.

Mine is a 2001

I have a hard time recommending any specific car I have not checked over myself. But I do have to say on a general point the XK8 is a good car overall if you are willing and able to do some repairs. DIY most defiantly the cheaper way but do expect to work on it from time to time. My suggestion like many others is educate your self as it looks you are and be thorough when checking the car over. If it is running ruff be super careful due to the possible Nikasil cylinder linings could be damaged. This is worse than the timing chain needing replacement. The engine block would have to be replaced or re-sleeved at a machine shop if this is present. Hope not to scare you and do enjoy if you pick it up they are great road trip cars. As for price I suggest NADA web site for reference.

buy it

Agreed. I got that info after this and found the pattern I used was slightly different but it is holding still. Jag fallowed a center out pattern as well but a bit more of a top to bottom movement compared to the cross pattern I used.

These are my personal cars. I only work on a few family and friends cars out side my own.

I have done it on the red coupe but no video yet. I hope to do it on the black convertible this winter.

The plugs where gaped when I replaced them about a year ago (3000 miles), so no need at this time. I use RTV due to it being recommended by many auto manufactures. RTV is also quite easy on the wallet. I do agree there are options to sealing and you should use what you are comfortable with. I worked and trained as a BMW service tech through the 90's and early 2000's.

@@weekendwarriorgarage4402 No, 'side gapped'. Read my XK8 Bible.

@@weekendwarriorgarage4402 I work on aircraft and Hylomar M is the gold standard. I wouldn't bring RTV anywhere near my car. Maybe a bathtub.

I have no need for side gaping. This is usually for trying to squeeze as much power out of the car as possible. I am not trying to build performance just make it reliable. This also shortens the life of the plug and I do drive my car regularly. I would rather not have to re-gap or replace plugs more often. The one good thing you do gain from this is possibly a small boost in fuel mileage.

Aircraft have a much higher standard to maintenance do to the fall out of the air factor. I worked on many types of cars at a factory service center and many part kits came with RTV. It holds quite well. I will say having to clean up after it is a chore. Especially if it is poorly ( excessively ) applied. I also look at the cost. I don't need a $20.00 part when a $5.00 part will do the job. That being said I don't skimp on safety parts like brakes.
