Just finished rebuilding my 1978 SC 911 3.0 L engine. Installed it and everything is fine except that the engine starts to overheat over a shrot period of time.

Checked the timing - set ok although I havn't checked the advancment at 6000 rpm's. The fan shroud is sealed properly, the belt is tight. Have good air flow from under the engine. Temperature continues to climb at idle or higher rpm. Checked the pressures on the fuel system its ok and adjusted the airflow/fuel mixture both lean and rich - no change.

The engine probably takes a good half hour or longer to hear up. While investigating, I did notice that the oil going to the oil cooler under the right front fender does not get warm until the engine temperature indicator is just below the red zone on the gauge. I did notice that when I am driving, the temperature falls a little, not much - still over to the 3/4 way mark. It is possible that this could be causing the problem? Any suggestions.
