Still in the process of checking the gauge wiring. While driving the oil light illuminates green.
You're scaring me. low oil pressure is consistent to severe overheating. Oil pressure light not on or flickering at idle when started cold?
Need to limit driving and engine overheating until you can figure out what is happening. Do you have an oil pressure gauge in your car or just the light? The light comes on only at ridiculously low pressure (something like 7psi). Way too low for a running engine at driving speed. Don't keep driving it with that light illuminated.
I forgot, but if I recall you car has cooling flaps still in place correct? Flaps are necessary to direct air over the oil cooler. Flaps move freely and not bound? Fail safe of the stock thermostat and flaps is for the flaps to go to the full hot position that directs max airflow over the oil cooler.
Post picture of the flap position both cold and hot. I just dropped all my shrouds off for powder coat or I'd take a picture to demonstrate what is inside and what you're looking for.
Per previous post, you need a means to look inside engine tin though the spark plug holes to make sure you don't have a mouse house like this.
