NC IA | I agree with jedeka and pirlbeck. Those engines are notorious for sleeve cavitation/o-ring issues. But in defense of the oil cooler guys, I've seen a oil cooler bad enough to get coolant in the oil, once (on an IH 466.) But it had been pumping oil into the coolant also, for a long time prior. Pull the pan, and put 12 psi to the coolant system, I'll put a 90% chance you will see drips coming from a sleeve. | |
