Dear All,
On behalf of a friend of mine I have some questions. His Norton leaks oil from the cilinderhead.
What is the best cylinderheadgasket to use in this case?
What are the torqs to set for the cylinderhead?
(he has an old workshop manual wich states the torqs in degrees and perhaps because of that he tightened it up too strong. He also says that he does not dare to tighten it up too strong again otherwise the pushrod busses/tubes will tear/maybe the pushrod bus/tube distance is not accurate anymore because of leveling the cylinderhead after distortion in the mating surfaces.)
ive read on the nortonownersclub uk that leakage is also possible via the crushwashers on the stud's I was wondering if this is also the case for this model(model50 n13)?
Many thanks in advance,
Kind regards,
