Had a similar complaint on a M20 (E30). Head ended up being cracked thru the coolant passage & #5 exhaust valve seat. Although in my case it would blow white smoke and the cooling sys. had a ton of pressure. The coolant & oil were ok, but after approx. 1/2 hr the temp gauge would start to move towards the red. I also was unable to get any hydrocarbons to show up in the coolong sys. If it has higher mileage, I would recommend pullin the head for inspection and replacing the head gasket. Hopefully just the gasket has worn out & started to leak. It's a straight foward job. Good luck.
