The ground crew suggests the
oil galley pipe plug going to the first lifter galley on the drivers side is missing and
oil pressure on that side is going to the wrong place.....remove distributor and install the plug from the front of the block...make sure it's deep enough so the distributor goes back into place correctly....if this isn't the problem it's of course possible the head gasket was installed in the reverse position and is blocking the small
oil hole connecting the block galley hole to the heads oil galley hole....although it would heat up soon with the gasket on in reverse position.....
Do we have to dig deeper???
