Valve covers leaking after replacing

[Jaytee007]

Hello everyone!! I’m posting on this to see if anyone has ran into this before and to share this wonderful experience (sarcasm). I have a 2006 x5 4.4 the n62 engine with about 163000 miles. I replaced the valve cover gaskets at 160k because they were leaking real bad from the rear of the engine and on the sides. I noticed another oil leak the other day and behold it’s coming from the valve cover gaskets 😡 I didn’t use any sealant when I first replaced them just new gaskets . I probably didn’t tighten the bolts hard enough because I knew the valve covers are made up of plastic and I did not want them to crack. I did leave them pretty tight though but not super tight. I’m thinking about tightening down the bolts and cleaning up and seeing if that does the trick. Any input is greatly appreciated. I’ll also follow up on conclusion I reach
