Newb Oil Filter Question

You asked, it's an extra sealing surface. Without the 90° adaptor assembly the gasket under the threaded adaptor for the sandwich plate is also covered by the other 2 gaskets.

What else matters? If the filter isn't adding longevity to the life of the engine, who cares? That's literally the only reason the oil filter is there. I have no issues at all making more oil pressure than I even need.

Was your pressure drop comparison a long filter on a 90° adapter vs a short filter directly attached? Or was it short vs long both with the 90° adapter? Because that factory bolt and the additional distance in the 90° adaptor have to make a difference too.

Both were done with the 90. Even a short filter won't fit on one set of dyno headers I have out there. And I'm pretty sure I can't get a shorty on with my headers either, but I'm not 100% sure of that ATM.

When I put my clunker on the dyno I will check to see if I can fit a short filter with my headers.

Unless I'm missing something, I can't think of a way to check the pressure drop across the filter without using the adapter. There is a port on the adapter I can use that shows pressure off the pump. So between that port and the oil pressure gauge port we can see the pressure drop across the filter.

I know I checked this probably in 1984, but it was on the car and there was no way to data log it back then. Plus I have totally spaced off the results due to the passing of time. And some jerk *** stole that note book.
