Hi Everyone,
I posted this topic over on the RennTech site but as of yet to responders - so I was hoping someone has the a chain tensioner with part number listed below on a shelf some place that could compare my pics with the shelf item to see if they are the same tensioners.

1999, 996 C2 Cabrio

I am hoping some of the guys can help me. I am changing my chain tensioners and the 1-3 new tensioner does not look like the old one (the IMSto crank tensioner looked identical old vs new). The new part number for the 1-3 is 996 105 186 02. The new part has a much thicker head and does not have the 2 rings on the body like the old one does. The tops are not identical but with a little squinting the new part number does look a little like it has 2 rings on top. Has anyone run into tensioners looking like this old vs new or does it look like I got an incorrect part?

Thanks
(P.S. Charles Navarro from LN was kind enough to reply to say that it looks like the new head has the 2 rings)

Looks right to me

I am under the impression that chain rattle due to failing tentioners is a result of dry starts. Does anyone know what fuse to pull to delay ignition after long storage. Or has anyone added a ignition kill switch to their 996 and can describe the process ?

Thanks for the quick response! This site is the greatest.

Need to pull the fuel pump fuses. The chain tensioners that usually make the rattling noise on start up are located between the camshafts.
