Wow, what did I do?

I had a crack in my valve cover and I took it off and used some JB weld on it. I put the valve cover back on, did a boost leak test and all seemed good. Took the car around the block and came back and had oil all over the engine, not to mention vacuum at 10 in/hg. It's coming from the side of my valve cover on the passenger side. Apparently I didn't put the gasket back on correctly, and there is about a half inch gap between the head and the valve cover? The valve cover is obviously on correct, but is there more than one way to put the gasket in?

There's a half moon that needs to go back on, but it sounds like you have a double up of the spark plug gaskets to me. Take the valve cover off(that jb weld will melt anyway), and clean the head completely of oil/gasket crap. Then make sure you have everywhere covered with a gasket that needs it, and add a little in the corners of the mating surfaces.

Sounds like the gasket didn't seal right and with a gap in between the cover and head there's no wonder. I would suggest finding another valve cover and depending on how old the gasket is, a new one of those also. It doesn't hurt to put a little dab of silicone on the corners of the gasket to ensure it gets held in place and a good seal.

Well it was that half moon looking thing that I didn't realize was there. I put that back in. And what do you mean the JB weld will melt? People on here tell me they use it on everything.

People use it to seal the plug on the BSE kit, so if it doesn't melt on the block, I'm sure it wont melt on the VC.
