I just finished my engine install--1275cc--and found that there is no oil pressure. I did find a reference to an "oil prime plug" but no information on priming the pump if that's what needs to be done. I don't want to pull the engine if I don't have to. Any thoughts? When I put the oil pump in I thought I had all the parts in the right places but maybe not. Hope there's an easier fix than extract and replace. Thanks for any info. JSM
