Default Oil leak 95 12 valve

Recently had tappet cover replaced due to major oil leak. The valve cover gasket are leaking oil now. Is this due to the crank case not being able to vent through the old leak location anymore. Am i getting more pressure being built up under the valve covers. I removed the covers and the gasket looks fine. I do not seee any leaks under idle. Any thought?

I had the same trouble too! I added some valve breathers on mine and it seems to help out! If you wanna see a pic, i can upload a pic or too for you.

Did you check the vent on the tappet cover and see if its clogged?

The reason #5 is alot dirtier, its a different filter because the orange steel mess ones were discontinue and i bought the rest that they had. So the next best choice was that one!
