Question about Cadillac DeVille
After car sets overnight, when you first start it does it run rough and or does white smoke come out of the exhaust pipes? If not the check the oil for coolant in the oil. To best determine if the head gaaskets are the problem have your technician use the equipment to check for exhaust gases in the coolant.

These motors are famous for the intake manifolds leaking coolant.Have a pressure test put on the coolant system and look for a leak around the intake manifold corners.Check all four corners i've fixed many of these.
