Well, short story. Had to replace the oil pump, so went high volume. Plentum gasket, I don't know what they were thinking, had to be replaced. So why not give the Hughes Racing motor a nice gasket, seal, hose, fluids and cleaned it up. Took a couple of days but has been worth it. Installed a PCR chip under the hood as well. Can really notice a difference. Especially the fuel mileage. This upcoming February in with the hughes intake manifold and out with the plentum.
