Re: Spin on oil filter adapter gasket? SBC
Not strictly true, no single filter will pass enough oil, particulaly when cold, to supply an old style V8. Especially those small filters on stock Chevys, the PH30 type, at high revs some oil will go through the bypass even hot.
John, the disc valve tips sideways under the flow of oil when cold and sticks sideways on in the port, never seen it happen in a stock GM housing, only the aftermarket ones.
