So I was riding down the road today not pulling hard just driving. All of a sudden the car start running weak and would not go over 3k rpms. I pulled over real quick and looked down at the oil pressure gauge, no pressure. Pulled the dip stick plenty of oil, not leaking anything, and no knocking from the engine. Engine will start right up but no oil pressure. Time belt is still intact, AEM cam gears did not slip. What are you guys thinking? Its a b16 block out of a 2000 civic si with a b18 head out of a 1996 gsr. Any info would be great!
