Same here. Ive started to smoke test the covers to avoid having to keep cleaning up oil. I got one side smoke free and actually builds up some back pressure which is good. Now on to the LH side which is the trouble one due to the AC lines.....
The RH side isolved with extra sealant in the areas that were leaking. Suspect those may be just slightly warped enough to cause small leaks since my gaskets are new,
