PRESSURE WASH ENG THEN INSTALL SOME LEAK DYE IN CRANKACASE. AFTER YOU HAVE DRIVEN IT FOR ABOUT A WEEK SEEK A MECH WITH A DYE LIGHT AND ASK THEM TO DIAG SOUCE OF LEAK
Leak dye is a wonderful thing! Lol!
Probably either the head gasket or the valve gaskets leaking into the spark plugs. Need to have diag. and find out which.
