Default *** Valve Cover Leak after Gasket replacement.... - 05-14-2017, 06:55 AM

The valve cover was thoroughly cleaned clearing all the passages and also replaced with RB PCV. Car has 176k miles.

I saw couple nicks/hair line scratches on the mating surface, either they were there or I did it while cleaning the surface on the engine. Now I have a leak that collect on the silver Shield near the vacuum lines. I used Permatex Black Ultra on the new gasket. Thin bead only at the bottom length wise.

The bolts were torqued three times starting in the center in cross pattern. Fist two were done using fingers. As I didn't have a torque wrench that went that low. I gently snugged them as I had done on my 2003 e46.

After searching few forums people have suggested driving around and the gasket will cure and stop leak and some have found loose VC bolt after driving for a bit.

Update - When I took it for a drive I saw oil on chrome drip cover at the bottom circled YELLOW next to the vacuum lines and was smelling like burned oil. I did run the car again next day for a bit and went on a longer drive. Did not see as much oil on the drip cover.


Here's what going on I think.....
The drip cover was covered with oil before I replaced vcg and I think when I wiped the old oil it made it into the edge seam of the chrome drip cover circled in RED which is folded over along the edge and I think when the engine gets hot and it loosening the old oil. I checked the valve cover multiple times and not seeing any leaks from it.

Also I have smoke coming from the rear turbo which is what I think I was smelling...

Not sure what is going on with the pics..... PITA. Tried Mac NG. PC worked. Wish the site had a compressor to size it..

Are you positive that your problem wasn't a crack in the valve cover itself and not the valve cover gasket? I'm pretty sure that's what I'm dealing with in my E60 at the moment...

Are you dealing with similar issue? If it was a cracked valve cover. You'd see some sort of oil trace on the valve cover. Mine seems bone dry. Checked few times.

I had this happen to me when doing the valve cover on my car. It turned out it was just old oil that made its way as you said between that shield and the head. It will take a long time to burn off. I ended up using a foaming engine cleaner on that area then rinsing it off. make sure to cover all the electrical components. I used a garden chemical sprayer to apply the water rinse as I didn't want to spray a garden hose around under the hood. Then I blew it dry with compressed air. Hope this helps.

Lots of times the valve cover gasket rolls during install. Smoke test the valve cover for visual diagnosis.

Smoke Test is a good idea. Will be looking into that.
Thanks
