So about two weeks ago I removed the POS OEM plastic valve cover and replaced it with a brand new aluminum that I had powdercoated red. Yesterday I noticed an odor coming from the engine and when I went to check there was a small oil leak in the upper right hand side near the BOV. When I checked the bolts they were loose...all of them! The nearest the exhaust manifold (tubular from MAP) seemed to be more loose than the others, but they were all loose to some extent. I haven't heard of this happening to anyone else before but if anyone could give me some insight I would greatly appreciate it. It seems like it might have something to do with heat expansion but I don't know. Could I just use some blue lock-tight and call it a day? Any inputs would be greatly appreciated.

 

yes you could just use some blue loctite or if you dont wanna use loctite you can use a flat and lock washer to keep the bolt's tight.
