Rb25 no oil pressure

Postby Eragon240 » Mon Oct 11, 2021 6:13 pm

Made the mistake of buying someone else’s project. Trying to get oil pressure on an rb25 and I’m not getting any. The engine had been sitting for 2-3 years so I shot oil into the oil filter inlet and then cranked it for 15sec and saw nothing, want to make sure there is nothing else I should check before replacing the oil pump
