Hi

The reason I was asking was because the engine had been sitting for a while and wen i started it the oil pump had lost its prime so therefor fuxxed the shells , but now its re built and i fitted a gauge and a heavier spring in the pump  i am getting about 42lb when turning it over on the key. so it should be ok at that.

thanks for the reply

cheers
