Im having a bit o a head scratcher!
Once apon a time. . . .There was oil getting onto the manifold and making a smell. I changed the rocker gasket and thought that was it. Now it looks like its coming from the filler cap? I checked the O ring on the cap, it looks ok, but for good measure i ran some PTFE tape in the gap before replacing the O ring. But still the same! Could the breather hoses be choked making back pressure and forcing oil out of the cap.
Sorry about the long thread. just trying to cover everything. Oh the cars just over 65k.
Any advice apreachiated.
