Re: B20v
Low oil pressure could be caused by a few things. Being that you had the motor assembled recently you might want to check your bearings to make sure clearances are correct. Also if you put the head on, not sure if you noticed but there's a o-ring that goes on the deck of the block that is used for oil pressure. One time a friend and I rebuilt a motor, forgot the o-ring or it fell out and we had low oil pressure issues during a tune. We realized once we took the head off that the o-ring was missing.
