I have replaced the head gasket twice, exhaust riser, and checked compression (110, 115, 120 120). Still have water in oil. What do I do now to find the solution? The engine , which is probably a '62, runs real nice. No other problems.

i have had this same problem before. it turned out to be a crack in the cylinder sleeve.

did you have the head worked while you had it off?
