Looking at an older boat with twin 454's. I see slightly milky looking oil noted on starboard engine dip stip. Possible causes?
Manifolds, Cracked block, head gasket? Compression check shows all cylinders between 130-140.
I think winter moisture from sitting but have doubts as port engine has normal looking oil.
