This problem has came up here many times over the years . This method has worked for me .

guys I appreciate the help! I just could not see how oil could be coming up, around this stud. if it was on the outside on the exhaust side I might believe what I am seeing, but not in the center row of bolts! I am going to retorque the head & I guess we will see what happens. thanks, will post the results later this spring
