Valve cover gasket
« on: April 01, 2023, 02:59:13 PM »
I’m pretty sure I know the answer to this but I’m going to ask and hope for magic, lol. Can the valve cover gasket be changed without pulling the motor? Thanks in advance!!

That’s what I suspected after staring at it for an hour or so. Thanks!

Normally gaskets are baked and glued in place from heat and age. You will never get the gasket surfaces clean enough and likely push old dried flaking gasket debris into the oil system. So you have a pooched and leaking engine instead. Now if you messed up a new gasket install then it will come off in one piece. Use your judgement cautiously here gentlemen.
