Thank you

You need to check the engine manufacture date to be sure. The last plastic tensioner engine was supposed to be 010813xxxx, but I believe there were reports of a few engines from later that year with plastic.

 

Your engine should have the 2nd gen plastic bodied tensioners. The 1st gen and 2nd gen tensioners both had plastic bodies, the 2nd gen had design improvements in how the plastic was formed to try to prevent stress cracks from starting at the usual trouble spots (along with the addition of a spring to prevent rattling noises when a plastic slipper was lost). The 3rd gen tensioners are the metal bodied design that is regarded as the only really bulletproof design.

I recently replaced the 2nd gen tensioners in my engine (2001+ replacement engine in a 1998 car). Thanks to the added spring, no noise was apparent even though one tensioner was severely cracked and had lost a slipper.

 

Samil: how do you know? Have you access to engine number from his VIN?

You might have metal tensioners: check the engine date. Later than August 13, 2001.

But why take the chance, pull the cam covers and confirm.

 

Thank you
The car is located in another state. the Jag dealer here in Los Angeles is not very friendly and did not want to give me the engine number !

So I am in a tough spot! Not sure who to call

 

Any dealer can convert the VIN to a 'build' sheet with the engine serial number. No guarantees but if you manufacturer date is December '01 it is very likely that you have metal tensioners.

 

I just found out that the engine number is
0111070832

so I should be good .. correct?

 

Yes. Nov 7 at 8:32 in the morning is later than August 13th. But, just to be sure . . .

How did you find the number?

 

Another member told me to call the dealer ,and to give him the VIN number Using that number the dealer was able to tell me when the engine was manufactured .

Interestingly enough the sticker on the door jam said 12/01
not November...

 

Engines were usually built several weeks ahead of the car assembly.

 

Thank you guys ..
