I have my valve covers off to replace the gaskets and install new spark plugs. I don;t have a record of the secondary tensioners being replaced so I took a few pictures of them hoping that some sharp eye can identify which generation they may be. 1997 XK8 Convertible 104k miles

Any knowledgeable observations?

Thank you in advance.

 

It LOOKs to me like your tensioners have definitely been upgraded as the whole body looks aluminum and only the shoe is plastic... but don't take my word alone, let's have everyone else chime in as well...

 

They are gen 3 (Metal).

 

Thank you for your replies! I have been worried about those damn tensioners for a long time. It's nice to know they are the latest and the greatest. One less worry thanks to you guys! Rplaced the gaskets and spark plugs. They were pooling in oil and the plugs all look fouled. New plugs and gaskets and the car runs like a dream!
