What to do if your 1998 XJ8 Rattle?
My 1998 XJ8 3.2 had this rattle. The best way to hear the rattle is to open the bonnet, and get someone else to start the car while you listen at the front of the engine. Make sure you have left the car overnight (really overnight) so that the tensioners have lost all their pressure.
Is there a blow by test on a Jaguar XJ8?
Jaguar dealers can perform a test to check for premature engine wear due to nikasil issues. It’s called a blow-by test. If you buy an early car from a dealer, make sure this test is gets done. Just because you have nikasil does not mean you have a bad engine. Without exposure to high sulphur fuel it will probably be OK.
When to buy an XJ8 / xjr8 1997-2003?
Buy an XJ8/XJR8 that was registered after 1st January 2000. By purchasing a car registered after that date you bypass the 3 biggest issues. Your car has avoided high sulphur fuel, you have the upgraded (2nd generation timing tensioners), and your car won t stall on motorways (upgraded throttle body).
Why does my Jeep stall when I start the engine?
If it starts, the fuel pump is the problem. If not, the engine should be checked for spark. It could be a sensor or computer-related problem. To be absolutely sure, raise and support the back of the Jeep on jack stands, unless the height allows you to crawl under the back without raising it.

Why is my XJ8 engine making a noise?
Research has shown that a noise can originate at the chain tensioners to cause a resonance in another part of the engine. A revised, spring assisted, secondary timing chain tensioner has been introduced to eliminate this concern, commencing at engine No. 98102106XX. Introductory VINs are not yet available.

What happens if a tensioner fails on an XJ8?
XJR8s are also susceptible but possibly to a lesser degree because they use a simpler timing mechanism. The tensioner’s job is to keep the timing chain tight. If a tensioner fails, the timing chain becomes loose and the chain can jump one or more teeth on the cogs in the engine. Apparently one jumped tooth results in rough running.
Can a car stall with a bad throttle position sensor?
The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.
