Leaky spark plug gasket need answers

[nube90]

My spark plug gaskets are leaking dumping oil into one of my spark plug holes ive redone it 3 times already the first time the one on the drivers side was leaking so, I took the valve cover off and put RTV on it put it back now it was the one on the passengers side, so i bought a new gasket set and put RTV on it now the middle one on the passenger side is leaking any suggestions!

Test your pcv valve, if its not functioning right it can blow back oil into your spark plug wells.

Don't use RTV, they weren't designed to use any type of sealer. The only seal on the whole engine that gets RTV is the half moon cam seal.

To test your pcv valve first make sure its hooked up, After you confirm that see if you can blow through it, if you can its good and if you can't you need a new one.
