Pulling down a combine power unit 262 gas for use in a loader. Drained the coolant and there had to have been close to a quart of oil in it. There’s no oil cooler for it to bypass and I would think bad o rings in the cylinders would result in coolant in the oil, exact opposite of what I have. Anyone ran across this before?

Never seen that in the 262 family. I had a 7020 one time that had oil in the radiator AND coolant in the engine oil and it was just the usual sleeve Orings. I did have a One-Eighty one time (and only one) that I bought to flip, knowing it had oil in the radiator, according to the owner. I didn't investigate, but bought it anyway, figuring it was just sleeve Orings. Well, it turned out to be the main oil galley down the right side of the block had a flaw in the casting and it was bleeding engine oil right into the sleeve Oring area thru that flaw in the cast. Never seen another one like that.
