Hey guys just finished putting my OEM rebuilt motor back in today. Everything went very well, started up first try instantly.

However there was a rather large oil leak coming from the side of the block right in front of the CTS. There's a picture of the seal it's leaking from below.

What is behind this seal, because I can't for the life of my remember, also couldn't find it through searching and the FSM doesn't give it any name. Thanks for your help.

that's a timing chain tensioner, a new gasket is like 11-13 bucks. and you should've replaced it instead of reusing the old one. The one linked is a dual layer gasket. I've never gotten a leak on my engine again after upgrading to this one.

Yea I did change it which is why I was really really surprised that It was leaking. Now that you mentioned what it was I feel like an idiot for not being able to remember.

Thanks a bunch man.
