early Lincoln LS V8, is timing chain tensioners an issue?

[JaguarXJR02]

I have read about how pretty much every jaguar with the 4.0 8cyl engine with a build date before sometime in 2001 is usually equipped with plastic timing chain tensioners which are prone to failure. The 3.9 8cyl in the Lincoln LS is the same engine pretty much. My car's build date is august 2000, I am wondering if this plastic timing chain is an issue for the Lincoln LS version of the engine. On the Jaguar forums timing chain tensioners is the big concern for everyone with a pre-2002 XJ, is it the same for the LS?

Yessir.. If you search you can find some info

To join the chorus here, I bet it would have been easier to do a search than it was to write the paragraph asking the question.

Also, you can use the jag metal tensioners instead of the plastic ones.

not to steal a thread, but are the jag tensioners expensive, and is it a hard job putting them in

Chain guides

I have only a little less than 150K miles on my '02 and everything's fine so far. We don't hear too much about the plastic chain guides (proper terminology) here, but a failure in this area usually creates a piston/valve crash so the failure is catastrophic.

The AJ engines used for road racing have specially-made guides because this is a known trouble area. The latest design from the factory is much superior to the older stuff. It's possible to work on the area with the engine in the car, but it might be simpler in the long run to simply pull it out first.

Search, dudes! There's whole threads on it.
Took me about 60 hours of work, with a friend (60 hours each, I should say). Lots of cussing. don't want to do it again.

yeah I didn't have much luck with the search, I suppose I need to try additional different types of combinations of search phrases. Thanks for the input!

Well crap, I guess this answers my question...My wife's LS has Almost exactly 150,000 miles on it now and today when I drove it I noticed a loud knock/slap/something noise coming from the front of the motor.

This is gonna suck.

that's unfortunate, I only have a little under 120,000 currently but I feel like the car is a bomb with a short fuse at this point
