Head gasket options for high boost OM603
Head gasket options for high boost OM603
I've heard of people using 606 MLS but assumed it involved machining the head and block to a much smoother finish than what the factory leaves for composite gasket (quite a rough finish).
I guess at this point what have I got to lose? Another head gasket? LOL. This will be #4 if I include the OEM leaking one the car came with at 255k when I bought it.

I also don't have the tools to pull the pre-chambers currently so I was sort of trying to avoid that... it's always failed in a different spot too and at varying/increasing power levels so I didn't suspect one part of the head to be a particular issue.
