Just replaced the upper oil pan O-rings on a 2018 Subaru crosstreck for a little bit of oil in the coolant, ran it trying to bleed the air out of the system for about 15-20 minutes and then all of a sudden a ton of white smoke, when I removed the intake there was a bunch of oil in there, apparently coming from the PCV, any thoughts? Did it blow the head gasket? I bought it recently and know it did over heat due to a blown upper radiator hose (caused by the oil) but not sure how bad. Looking for advice on what could cause the excess oil in the intake sucking into the cylinders. Blown head gasket now pressurizing the crank case is my best guess?
