O.K. guys I need some help here. I put a set of GT40P's on my car back in Sept. I noticed that the car started to have some cooling issues after that. I have a autogauge Temp gauge that is mechanical and the needle would go all the way up to 220 or so and then go right back down to 140 or so. This would happen right after I start the car and drive for only a couple miles if even that far. And it seemed the harder I drove the car right after starting it the more it would do this. One day I drove the car about 1 mile after it sat all day and I turned it off to get gas. As soon as I started it , the guage shot straight up to like 240 and no matter what I did I couldn't get it to come down. The pressure in the radiator was ungodly. So I noticed that the radiator smells like exhaust. And I have a steeda air filter on ther to catch oil from my pcv valve and every once in a while after you drive the car, that has some oil in it along with milky stuff. Not ever alot of it but a little here and there. So I have kept driving the car, racing it until OCT. and I even had it dynoed. I have sprayed the car on the dyno and about 6 passes back in Oct. I am still driving the car today. I still have the exhaust smell in my cooling system. Whats this sound like. A head issue or a block issue. I have pulled the heads once already and had them milled just to rule out any warpage issues. I did that back in early Oct. I have changed the oil and it looks fine. Oil on the dipstick is fine. It makes no sense to me.
