Yes, I saw the picture- - - -that's why I asked. The original canister-type bypass filter has a 1/16" hole in the return tube that restricts the oil flow through the filter element before it returns directly to the oil pan. If a regular spin-on filter is substituted for the cansiter without restricting the flow, far too much oil gets bled away from the main and rod bearings, and the oil pressure will be extremely low. A spin-on filter is convenient, but unless one with a very tight-weave element is used, its filter media will be way too open to provide good bypass filtering.
