I'm new to Jags, so please guys, take a look at my XJR's secondary chain tensioner! Is this what you call iron or plastic tensioner? I don't know it is related or not, but my engine is the iron cyl. liners yet, instead of the nikasil one. My car was built in 2000 Aug, but the engine number is higher than the last nikasil V8's number. Is it possible, that it's left the factory with iron tensioners?

 

No, your car has had a replacement engine, probably by the dealer.

Yes, nothing to see here, all quiet on the western front - you can sleep easy. From what I can see, you've got the latest tensioners and guides. No worries!

 

Good news! Replacement engine! That could be the answer to that my engine number is 00082123--, and the last nikasiled engine's number that was built almost at the same time with my car is 0008181043. Thanks again Sean! One more pics.

 

He also has the intake cam damper - Is that on all AJ27 SC cars? Neither of my AJ26 SC engines has that, although I have seen it in the parts list.
