I'm trying to understand how would the soot/grime get into the thermostat per pics attached. Could it be the manifold has a crack sipping water in mixed with exhaust gas when operating? The engine is raw sea water cooled.
Any thoughts or ideas? |
Do you know the compression in the cylinders? Milky oil and moisture could mean a ruptured head gasket between those two cylinders with issues. That could also account for the dirty thermostat. You can get an inexpensive compression tester online, or borrow one from an auto parts store. It's an easy test to do.
I recommend you start a new thread on this issue.
