See this link. All I did was a simple Google search to find this. Head gasket is the most common problem on the m series engine. You can send a sample of yoir oil to a company and they will tell u exactly what is in there. Very well could be antifreeze thining your oil causing low pressure. there is a block test you can do to tell u if you have a leaking head gasket. Is there any sign of oil in your antifreeze or any dissapearing coolant? How old is your oil?

I will check the oil today it seemed ok about a week ago when I checked it. It was not runny and color was good. but today is the first day I have driven it I had this overheating problem about two years ago. I parked the car and am now trouble shooting.

After reading other threads this is starting to look like a bad head gasket
in its infant stage.

Another thread said to look at the number six cylinder would this be the back cylinder away from the front of the car.

BTW, your oil pressure is normal. These cars run a low pressure oil system, and on cold start up it should be over 40psi, at operating temp it can be as low as 3psi
