She was purring like the cat she is, a 2000 XJ8 and then just stalled. Trying to restart her didn't work and it had an unusual sound while cranking.
I had been worried about the timing chain tensioners and thought I would take a peek and so removed the cam covers to reveal tensioners that were breaking up. So I gathered all the tools and all the recommended parts,
[thanks again to blackonyx of this forum], and went about replacing chains and tensioners, water pump etc.
Have not been able to get her started yet. Thought about bore wash and tried a couple of times to add a teaspoon of oil to the cylinders and was rewarded with a more familiar sound as well as some firing as if it at least wanted to start. I went ahead and tested fuel pressure and got 38lbs.
Today I performed a compression test and these are my results:


Passenger side back to front- dry80 wet135 dry75 wet135 dry60 wet120
and dry80 wet150


Drivers side back to front- dry50 wet125 dry60 wet80 dry90 wet125
and dry60 wet95


I'm thinking of doing a leak down test next but it already seems likely I may have valve issues on drivers bank.
This all began as the post " Closing after surgery " so its been a while.
Haven't lost my mind just yet but would welcome a steady hand.

 

When the car stalled originally did you have any codes? You might have had other problems besides the tensioners. I think even with the compression readings you have it should start. I made the mistake on my rebuild by putting left side cams on the right side head. I had zero compression on that entire bank. It did start but of course it ran like Crap until I undid my mistake.
