I Was Doing My Normal 4.0 Engine Refresh, But This Engine Fought Back!

Rather than stacking this core up with all my other Engines, I decided to just stop what I was doing and turn this back into a good engine. It went pretty well but the oil pressure was not to my liking at all. But taking this negative to my advantage, I will use this engine to answer the age old question of where the oil pressure is actually going!! Thank you!!
