Hi guys i have a query about the allen bolt to the left of the head which people have used for oil feed in the past. Is this a constant pressure area or does it increase with revs. Also is it 1/8 fitting?
people have talked about using it, not sure if anyone has done yet though. i tried undoing one on a spare head and it was siezed in solid, it'd need drilling out and re-tapping. but if you can get yours out, measure the thread and stick a pressure guage in it.
