I am trouble shooting some issues with oil pressure with a new motor and believe that I might possibly be missing some galley plugs. As far as I know there are three located in the front above the cam, three in the rear in the outer side of the block one in the main cap around the number 5 cylinder and i was told one more that is one more where the drive gear to the oil pump engages. i have been searching all over the internet tryin to locate a diagram showing thier placement with no luck. If one of these is missing would I experience no oil pressure? thanks to anyone able to help
