Oil Pressure

[BrianJ]

I need some help with an oil pressure problem. After installing a new sleeve, piston, and valve train, the TO20 started right away. After my initial excitement, I noticed the Oil Pressure guage was reading 0. No oil pressure I have cleaned the pump, inlet tube, oil relief valve, and checked the oil pressure port on the side of the block. The guage moves when I pushed air into the guage tubing, so I know the guage is okay. Any thoughts on why I don't have any oil pressure? Clogged oil galley, maybe? How do I clean the oil galley? Is there a way to prime the oil pump? Thanks!

the pump should be restored to like new.

also the main bearings can be in upside down

Prime an oil pump by filling it with vaseline during assembly. Perhaps the oil line rubber fittings are sucking air. Should be available from your local Hyd cylinder supply/rebuild shop.
