Original ulster engine rebuild
#17
Surprising that the pressure fed engine retains the oil baffles. Maybe a mousepower to be gained by reducing pumping loss? it is interesting that get low oil consumption with slipper pistons; books used to emphasise influence of piston skirt edge on oil consumption.
Do you happen to know whht the current valves are made of? XB and inferior steels, which many aftermarket were, are magnetic. Up until late 1950s when XB was phased out for exhs near all makes needed occasional valve replacement/grind
