Vannin' Home Forums Thread Like Summary - Mopar 360 valve cover

Picked up a dodge in Seattle. On my way home to Minnesota. Long story.. but cracked my valve cover. It’s small, but it’s leaking. I’m in Helena MT, got it towed to the closest shop, and hoping to get back on road ASAP.

It’s Sunday, so nothing is open. Got a room for the night, and I’m going to start up on it tomorrow. Hopefully with sone guidance/help from the shop.

I’ve been looking into it a bit, and it sounds like a lot of ppl use JB weld as a temp fix until it can be replaced. Anyone have experience with this?

Not sure if the material is weld-able. Or if a welder in area would be able to do so.

Thought maybe I could get sone feedback/help from you all.
I appreciate your time!

Since the oil sloshing around inside the cover isnt under much pressure, you can certainly use some J B Weld to fill the crack, inside and outside to be sure. it will dry, not cure in a couple of hours. I have a valve cover if you cant find one,,,but they are common small blocks ( 318 340 360).

I wouldn't be too quick to guess high pressure, as that shouldn't be an issue. I bet the PCV is clogged and there is probably a little debris around the gasket, or a crack in the gasket causing it to leak there. The PCV gasket also might not be seating correctly in the aftermarket valve cover, if the gasket was meant for a stock steel valve cover, the slight difference in thickness between the two valve covers could cause issues.
