I know they recommend a non detergent oil for water pump bearing lube because of persistent water intrusion.
So on an engine that has the same issue of persistent small amounts of coolant intrusion, what if anything can I do.
Non detergent oil apparently has no wear additives either. Is this correct?
Does zddp react with coolant? If not, I could use ND oil and add zddp to make my own custom formula.
I'm wondering about a marine oil as well but don't want to spend a lot.
I don't care about detergents as the engine is clean as a whistle.
