Updated chain tensioner - IMS to Crank

[jaykay]

Okay here we go again

Just went pick up the most up to date chain tensioner for the IMS to crank chain. It's the one with the external spring. I was told that this spring type is not compatible with my early 2000 986S engine (dual row IMS bearing) as I have a roller chain type IMS drive and not the newer tooth drive chain.

These changes ( tooth chain ) were instituted for engine numbers M96.21 67 1 02086 onward. Apparently they could tell from my VIN that mine was an earlier engine (not sure I trust vin based engine component listings where is the engine number again?). I believe this is covered in a bulletin 8/00 1551.

So I belive some of you have put the newer style tensioner in irrespective of engine series and earlier chain type . Is it okay? Any issues? Did it help to chain rattle on startup?
