#46 of 53 00 XJ8--Starter or Motor?
Sep 23, 2010 (6:41 am)
I have an oppurtunity to buy a 2000 XJ8 for a possible steal. Owner was told the motor was locked but it turns over fine by hand. Try to jump it and it just gives you a hard click at the starter. On any other car, I would buy it, put a starter in, and cross my fingers. Problem is, I know nothing about the Jags and any other potential explanations??? Any advice would be appreciated.

If it were hydro-locked (bent rods) it might turn part of the cycle through the compression or exhaust stroke.
I would only buy it on the presumption that the locked motor diagnosis is correct, and pay accordingly---in other words, pay the junk price for it. That's the only rational way to approach it.
A 2000 XJ8 is not a valuable car. If you really want one, just go buy a running one for not a lot of money.
Basically, this car, with a bad engine, is totalled. And even if the engine weren't bad, you still can't check out all the other functions (AC, trans, suspension, brakes, electronics), so it could end up running and *still* be a loss to you.
I'd say "pass" or buy it for what you can sell it to a wrecker for.

Thanks Mr. Shiftright. Always good to get the voice of good reason behind you.

Well you could get lucky, but place a small bet in this case, since the house is stacked against you.
#50 of 53 Compression on engine
Jan 24, 2011 (11:17 am)
I had the valve cover gaskets replaced to repair a leak and after 6-8 months the leak had reappeared, this time causing smoke upon going up a steep hill as oil from the oil pan was full of hot oil and would get thrown across the engine parts at very hot temps therefore causing smoke. The shop was going to redo their work on the valve cover gaskets as I could point to the oil in the oil pan and show leakage appearing on the valve cover that covers the ignition coils. By the time the parts came in two weeks later, the car starter would engage but the engine was not sparking at all. My feeling was this was oil leak damage to the ignition coils where you can see oil spots on the valve cover. But the shop said it was a compression problem with the engine that had to be towed to the dealer. Do oil changes affect engine compression? That's the only thing I had done just prior to getting the shop to agree to redo the valve cover gaskets.

Oil change will not affect engine compression, but over fill of oil can do damage
in going up a steep hill should the oil flow back in the oil pan and the crankshaft and piston rod ends hit the oil. This would build pressure in the oil pan and valve covers making for oil leakage and a engine mess.
Also if the valve cover gaskets were very bad or the covers loose this could have made you problem. Replace the valve covers is not a big deal, and maybe a good pressure wash and hot air dry will take care of you problem.
Let me know!

when I try to start the car with the main key it does the system check and shows nothing wrong, but want start the car when turn all the way, there is no sound at all.The key will unlock doors and trunk. The green Valet key will start car and work doors, But the Owner Manual it tells not to use for normal driving. If anyone can help with this problem I would appreciated.
#53 of 53 Jaguar XJ has too many problems

It seems as though the XJ8 from 1998 to 2000 all of them experience transmission failures or engine failures or both, and many cases multiple recurrences.
So if I buyt a $2000 XJ8 from those years now, I probably expect to get about 10000 miles of trouble free driving and after that it would be $10000+ in repair to fix problems, rebuilding transmission and rebuilding engine must be accounted for.
