I know that any coolant in the oil is bad. I posted a UOA in the Diesel section but it looks like not too many visit that forum. I have 11ppm Potasium and 29ppm sodium. This does not sound like alot to me. Or is it? I bought the truck and believe it had been sitting 8+ yrs. Hopefully it only leaked that amount in the whole 8 yrs? I changed the oil that had the coolant and have sent another sample out. I will rebuild it but right now I don't have $8K to do it. Will it hurt anything to let it sit in the pan and ocasionally drive the truck across the yard where I can work on it? [ February 15, 2006, 11:35 PM: Message edited by: Chris142 ]
Any coolant in the oil is bad. Coolant destroys the coating on the rod/main bearings, thus causing them to wear faster. If you are going to rebuild it, why worry about it.
