Coolant in crankcase

cbaker425 · Jun 15, 2014

I have a 1520 gas engine that has started getting coolant in the engine oil. Pulled the head and pan and do not see any obvious leakage. Any suggestions on what to look for. thanks Chuck

Pull sleeves. If you had looked before removing the head you would have seen where it was coming from.

With the coolant in the engine you could have pulled the oil pan off and looked up at the bottom of each sleeve and if coolant is leaking into the crankcase. There are rubber o-rings on the sleeves that can leak also the sleeves and/or block can corrode where the o-rings are.
