how many hours are on the oil cooler, has it been ran in the salt and have you ever lost an engine that has been on the cooler.
I have no clue on the hours. One motor milked the oil (head gasket?) while on this cooler. I've pulled the two fittings into the oil chamber and it looks fairly clean. These coolers can be completely dis-assembled and cleaned out just by pulling the ends off. I don't see a gasket, so I'm sure the ends are o-ringed. Dave
