Finally some information that is relevant and makes senseThe 226H oil canister is a whole different animal. it attaches to the side of the block. The restrictor is built into the bottom of the canister and passes through to the mounting bracket by means of a ball bearing.
Most likely the end of the hole that the bearing sits in is peened to a smaller diameter.Ok,so I know one hole is inlet,the other drains to pan,how would this ball bearing be held in place without falling into block where it bolts to?
