OM606 Experts - I need you! :)
The rubber O-ring in the photo, I'm all but certain seals the metal coolant return at the rear, left side of the block (as you sit in the drivers seat). The aluminum seal however, I cannot find...
Anyone know where it goes?
I don't recall removing the aluminum seal during disassembly and I have yet to see a gasket manufacturer tell you what all you're getting.
it looks like the timing chain tensioner
