Just got my rebuilt engine running and I pulled the valve covers off to check lash and noticed water oil milk shake around the drivers upper rear head stud. (First pic) I torqued the heads again and drove probably 20 miles and just checked after sitting for two weeks and came across this.(2nd pic) These are pre 2002 e heads. New felpro 1016 gaskets. Could my head bolt hole actually go into the water jacket?
