Finally got around to getting into the Olds after blowing milky oil out the valve cover breather.
I checked the oil knowing it was going to be milky. Yep it sure was!!!
Popped the valve covers off... yep milky oil there too.
Pulled the intake and that is when it got real ugly! Milky, frothy oil all over the underside of the intake. Milky oils sitting in the lifter valley. And what appears to be surface rust and oily water near the left bank around the #3 cylinder where the head meets the block. Intake gaskes looked good especially around the water passages.
Is this a head gasket failure around the #3 cylinder???? When it started blowing milky oil out the breather the water temp was right around 150-160. The engine showed no signs of over heating.
Water pressure is suppose to be around 18-20# (need to get a guage) with my PRV on the inlet water.
Header water is coming in a bit early (1500-1700ish) need to rebuild the Bassett header t-valve.
