I have a problem that has me stumped. Just swapped a lower mile engine into my truck because my other motor cracked a piston. Well since the swap it has been one problem after another. First it was an oil cooler leak, so I rebuilt it, next I had diesel in my coolant so I replaced all of my injector sleeves and now as of yesterday I had oil in my coolant. I read that it is most likely the oil cooler so I swapped one that had been rebuilt from another engine I had sitting here. Flushed the oil out of the coolant and changed the oil and went for a drive. In a 5 mile drive I pushed almost half of my oil into the coolant. There is very small traces of coolant in the oil so where is the problem? Head gasket? Cracked head or block? Im at a loss. Sorry for the grammar, I'm on my phone.
