So glad I didn't use a stop leak! Leak test showed only 60% in all cylinders on the right bank so I pulled the heads. The mls gaskets were mutilated. Most of the coating was in chunks or bubbly with coolant. Had coolant all up in my valve ports and top of the pistons were flooded with coolant. ( wondered why the coolant wasn't draining fully) Totally amazed my oil pan wasn't full of it too.

I order a graphite composite gasket instead. Nooooo way, I'll use another mls.
