Im not sure why I have oil in the plenum ? The breathers go off to atmosphere I have only done a 1000 miles where would it be coming from or is it not a problem ? Many thanks
Old stale contaminated fuel residue from the cams overlap mixed with spent ex gases etc, when off cam you have all kinds of weirdness going on in that plenum, it's evidence of single plenums don't like lumpy cams too
That sounds about right I have a really lumpy cam too so that would explain it, I thought it was a problem like stem seals ......... I will put it back and leave it ! Many thanks
