There is a plug (looks like 1/4", but I'm sure it is not as it is metric) at about the 2:00 position as you look directly at the water pump. It is directly below where the DIS would be and behind the alternator. I'd like to try hooking an oil pressure sender to that port. Anyone know the size and pitch of it? Do you think my odds are slim to none of finding an adapter that goes from metric to 1/8" NPT?
