Does that fitting run to a cooler, then back into the oil pan? If you shimmed the oil pan valve to have the higher psi, could you do that? Just trying to take a guess here, not really well educated on how to tie the two together....
I always forget, on the back of the engine, does the oil come out of the center outlet in the back, or the one right beside it.
Randy, could your spin on adapter be modified like this? Is there room on the side to tap and put a fitting like that on?
