Chain Tensioner Parts

[PhrogPhlyer]

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 IMS to 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

I did my chain tensioners about a year ago, so I don't remember if the new ones looked any different than the originals. I'd think that as long as the overall length is the same and the o-ring is in the same place and the diameter is the same it should be ok (in other words if those things are the same, the rest of "the look" doesn't matter)...good luck
