Do my own IMS?

Jake,

Most of the retro fits I have seen have no seals on the bearing. Suspect you could make the case that it is easier to get dirt into it by using oil supplied by the pump but bearings that are open are also at risk as they are partially immersed in unfiltered oil. Correct?

I'm sure not Jake, but I agree with you. The worst of the trash in the oil likely sinks to the bottom near the pickup or outside the baffles. The pickup sucks up the oil, it passes through the pump and into the filter.

So my take on stealing oil -

From the pump, great from an overall oil pressure standpoint, not so good from a clean oil standpoint.

From an unused port on the head - great from a clean oil standpoint, steals oil pressure from that head though.

From an adapter at the oil filter- great from a clean oil standpoint, great from an overall oil pressure standpoint

From a splash oil standpoint - great from an oil pressure standpoint, so so from a clean oil standpoint.

My 2 cents.
