On this V8 engine, timing chain problems are very common. Because the timing chain tensioners were made from plastic, they can fail prematurely and cause serious engine damage. A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may also be accompanied by a rough or uneven engine idle. Improved components are available to remedy this problem.

    Both of my top tensioners went the top fell off one of them and went through the timing chain which jumped the timing by a tooth. Luckily, no valve to piston damage! Now I need to figure out the easiest way to change the now streched timing chain. Looks like I need a whole bunch of special tools.

    Filled car to the maxium with suspreme gas. This has happened two times on two different motors. Drove about 1 mile,parked car went into grocery store came out tried to start car and only the starter turned over went into home came out, in few minutes car wouldn't start only starter turned over. Both times to the same shop to diagonsis it no compression on both sides. Had it towed about 100 miles to Jaguar dealer,they said I needed a motor and I told them I had only 47,000 miles on it, the timing chain are known to break, only thing they said another motor because mine might be bad on the inside. Now parked at foriegn car garage next month will be 1year says the same thing, I need a motor. Jaguar dealer charged $3,500 and I paid $2,700 for motot, garage want $2,000 for motor and $3,000 to install.I've had the car for 3 years and haven't drove it for a complete year and still paying for it and have tags and insurance.
