Been chasing some milky oil... Pulled the driver side head. I pour water in the holes between 5-7 and both head bolt holes fills up with water... not normal correct? perhaps i found where the oil and water is getting in when the head is on water pushing up into the head... just a thought. be easy on me i'm a newbie... smile best way to fix or what would you do? picture coming soon

Usual cause is the deck or head is little warped and the intake bolts are over tightened - it will lift the head up off the head gasket just enough - intake bolts are only 48 inch/lbs for the two outer and 78 inch/lbs on the four inner using a sequence to tighten. Use some sealer on your head gaskets around the water holes - just a light smear is all you need

A manufacturer of after market blocks I had drilled the head deck holes right into the water jacket...They have to be checked before assembly...

Indian head shellac on the block side stud, or bolt threads, and it won't leak.
