Question about Jaguar X-Type

1 Answer

We recently had the timing chain jump on an Xtype Jaguar 2.0 diesel. We changed the timing chain and tensioner and fitted reconditioned delphi injectors, the car now has a very loud knocking sound coming from the engine which gets alot quieter when the car is warm but it i still there, Timing has been rechecked and is ok, head has been off car and checked and is ok,fuel tank has been drained and new diesel added, egr valve has been blanked off, catalitic convertor has been bypassed, nothing improves the noise. this noise was not in the car before it jumped the timing chain.

Make sure you have proper sealing washers under injectors,and you have only one washer in place ,ihave seen it happen before 2 washers will cause a loud knock if not that get injectors calibrated good luck

Why does it jump time?


It sounds like you may need a timing chain tensioner.
I looked on e-bay and found a kit which includes an "upgraded" tensioner, and includes all the pieces, for only 60 dollars.
God bless your efforts.

I have a 2001 jaguar s type v8 that jumped timing i fixed it but its still making noise and running rough. I checked the compression and its at 135 on all cylinders, what do I do now?


i guess your engine had jumped valve timing due to broken plastic chain tensioners/slipper pads, common problem. are you sure you have got the valve timing right? not easy to do without the special tools. the compressions are to low they should be 165 psi minimum. you could have valve damage. if your engine had the old plastic tensioners then it is more than likeley to be one of engines with nicosil coated cylinder bores which wear out quickley. which will give low compression readings, recheck your valve timing first. you need a crankshaft timing tool which fits in place of the crankshaft position sensor on the flywheel housing and 2 camshaft locking bars to fit over the 2 camshafts on each bank.it is critical to get it right, hope this helps.

I just recently changed the Timing chain, Tensioner, chain guide, and top crank. When i start the truck the chain still clatters. I took off the Valve cover checked the guide, turned the pulley 360 deg....


i have had this problem with a ford scorpio 2.0 engine (euroepon model) and no matter what i done the adjuster would not come out and the timing kept jumping as the chain went slack ,so i improvised and made a spring to fit on the adjuster and the other end to the top of the cam shaft housing ,fitted rocker cover started engine and after a couple of minutes of running the oil pressure had built up in the adjuster mechanism .removed the spring and its been running ever since over 2 yrs now .Iam wondering how they do it in the factory on the assemble line perhaps the adjusters are pre filled with oil who knows

I have a Mitsubishi Pajero NM 2002 3.2lt diesel timing chain


I checked out the pajero forum, they don't mention the bottom tensioner as being the noise maker here but rather a sloppy chain, stretched beyond the tensioner and riding on the guides. The noise sounds like it comes from the fan area as a metallic chattering. They sell a chain that has a master link in it, and you don't have to tear down the entire engine again to get to it, just the top cover,, Cut the old chain, and use it to pull the new one through. Also, if your chain did jump its gear, it would only be a matter of 8 - 10 miles before the cam breaks. Hope this helps.

I have a 54 plate jag xtype and the nsf headlight bulb keeps blowing, the most recent one lasted just 3 days, the one before lasted only 4 months. is it a wiring problem or a jag problem?


my best guess on this would be that there is some undue vibration on that light assembly or some moisture getting in ... do you change both bulbs at the same time? you may want to change the other bulb at the same time as this one just to see if this solves your probelm. That should be standard practice on all cars and not just jags ... I have a passion for Jags.

Jaguar X-Type cam belt


These are chain driven. The only issue I have seen with these are the chain tensioners breaking. Generaly with chain driven engines, the chain will last the life of the vehicle, unless something like the tensioner or guide brakes. If it does break repairs can be fairly expensive.

Ford tdci 2.4 diesel engine as fitted to 1994 LTI TX2 taxi. Constantly replacing timing chain and tensioner. Five replacement chains and tensioners in 140,000 miles. Engine is serviced every 6000 miles....


cant help the only ford 2.4 engine diesel i know of is the york engine and that has a timing belt not a chain.Sounds like you could be a bit fastidious because all timing chains show wear on the tensioner,causing a bit of a rattle but unlike a belt it will not break just get a bit noisey,answer to that is to turn the radio up a bit
