The prima chain is actually the best indicator. It was only fitted to the engines with the newest tensioners from the factory.

The new ones don't last for ever either. But you get more than the life of the plastic ones. I already have changed a set which were 'dead'

Brandon, I wouldn't be concerned with your engine, it's an AJ27S with morse chains and Gen 3 chain/tensioner layout, it's a super slim chance of anything becoming an issue while you own it - I highly doubt you'll experience the dreaded tensioner issue earlier engines suffered from, your engine has Jaguar's remedies already fitted. Just sleep easy and enjoy.

Thanks for all the info, Daim! So since it has the newer chain, does that mean it still has the plastic primary tensioners? I would think that since the newer chain was put in, they would have changed the primary tensioners if they were plastic. But, you never know until you remove and see.

IIRC yours has the "newer" style primary guides, which are a plastic plate over a metal plate, you can kind of see it in dead center of the second pic where the primary chain goes down towards the crankshaft. Which I believe are the ones that are supposed to be used with your style chain.
