I think I'll junk yard the truck or just the engine sooner than let Cat open it and fix it... 250ppm is actually manageable i think. the oil was already old. I don't know whats the RATE of coolant leak into oil or how the coolant sealers have/will affect coolant getting in oil. At 250ppm the oil looks exactly normal and smells normal. I know a guy who drove 7months with 950ppm of sodium in oil before fixing the engine (and the engine performed the whole time - never broke)...
coolant bubbling back into bottle

Did anyone suggest isolating (remove the air outlet hose, test for bubbles, hook 120psi shop air to the governor redo the bubble test,ie either of these solve the bubbles R&R the compressor) the air compressor from the system to make sure the the bubbles and coolant are not coming from the compressor head.

um, coolant sealant worked. I used all three Bars Leaks from head gasket sealant to radiator sealant to tablets (clay with something) in various amounts lol. 1500mi not a drop of coolant lost but still get bubbles in coolant. i'm just counting my blessings at this point lolLast edited: Oct 19, 2015
