Could someone confirm which way around the (OA) adaptor for oil pressure gauge goes into the block? The threads are very similar (1/8" NPT vs BSP?)
And would you use a copper crush washer between the adaptor and the block and a fibre washer for the face of the pipe nut to push up against the adaptor and against the gauge end?
Cheers, image attached of the adaptor. Is it best to also vent out all the air in the tube so it is filled with oil (Clear nylon pipe).
Just got the new build running but oil pressure gauge didn't seem to get higher than 20psi there was also a concerning oil leak near the timing cover that's either a half moon or maybe head gasket. Definitely not coming from the new oil core/gallery plugs. So I need to check the oil leak and see where it's coming from, check the oil gauge pipe connections, and check the new shuttle oil pressure relief valve I put in (probably put back in my old one that I knew worked).
