crap, checked out the oil in the heads, was all milky, getting water in. Suspect it coming from the riser elbow gasket, was kinda old looking in an old wrinkled cover when I got it online. drained the oil from the pan, tried to clean and flush the engine with the diesel fuel. the oil in the pan was not too milky and we checked out the compression, every cylinder was at 150psi, so looks like we dodged the bullet. Question is, what can I use to clean up the engine from the remaining watered oil? We are planning to let the diesel all drain till tomorrow, fill the engine with the new oil, put a bew filter, unplug the water hoses from the manifold, keep the water only to the intake and let it run a little to see if there is any water leak left. if there is, then we will look for the intake gaskets and possible head cracks. also the head cracks are unlikely, since one was checked at the shop and the other was replaced at the same shop. if there is no water, than it means the riser elbow gasket was bad and we will flush the oil, use the engine flush and seafood, change the gaskets and put the engine back together.
