I'm new to the forum-I have a restored 65 GT that I have been papmering and driving hard for the last 15 years! I need some help though... I have a 1967 289 that I rebuilt 10 years ago-it's overheating and I have replaced all the pertinant parts-IE-Radiator, waterpump, thermostat, bi-passed the heatercore... I'm not having any coolant in the oil... Am I getting exhaust into the coolant... Any advise would be great!!
