Rebuilding another 3.4 M 96. This engine came in with the coolant & oil intermix. This was the classic cylinder head crack. I’m not sure who worked on this before we got to it, but there was about 5 pounds of silicone wrapped around the engine, including a piece of cardboard to stop the leaks around the front main seal.
We’ve cleaned it up and completely rebuilt, the engine with new valves, piston rings, rod bearings, main bearings, chains, tensioners,etc.
It should be a good strong leak free engine when we’re done!
