    Antifreeze coming out the overflow. There is no sign of antifreeze in the oil and there is no white steam escapeing the exhaust when the vehicle is cold What can be causing the builbup

    Intake gasket, or else a cracked head/ bad head gasket.

    No way it could be the intake gasket....... The water crossovers are separate from the intakes on the 6.2/6.5L's........ Cracked head or head gasket are almost certainly the problem though..
