Default Re: Low oil pressure in ZL-1

Remove your oil filter and look at the block. There are 2 large (3/4"?) holes. 1 large hole should have a check valve in it or you will bleed pressure like crazy. The valve is availible thru Chevy Performance Parts-Scoggin Dickey knows what it is if you tell them its for ZL-1 block.
