Did you replace with the one piece gasket? Or the strip gasket! The one peice is best your torque is not the issue ! All surfaces Must be clean and dri! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75232-mack-em6-300-valve-cover-bolt-torque/#findComment-570508 Share on other sites More sharing options...
Manwithaplan Posted 2 hours ago Author Share Posted 2 hours ago This is what it was replaced with, one piece but with the weird overlapping joint in it. Everything was wiped off before assembly, cleaned the groove out in the valve cover with brake cleaner and pushed a rag along the whole groove with a screwdriver. I guess I don't know why it's still leaking.
