That's exactly what I was suggesting. The PH 8 has a very open-weave filter element so enough oil can flow through it to supply the volume an engine needs to lubricate everything without excessive pressure loss. That means you'll get the same extremely inefficient filtering as every other engine with a full flow filter gets, as opposed to the close-mesh element the GM engineers specified with their canister filter. There are spin-on filters that we used for various types of hydraulic units in an industrial environment that would provide much better filtering while still offering the convenience of a disposable filter can. Research Baldwin or WIX for a filter that fits your spin-on base and provides as small a micron size as possible. All the PH 8 will do is look like a filter when compared to an original-equipment canister filter.
