I know the coolant in intake topic has been beat to a pulp. .. but with an egr delete, would a bad head gasket actually fill up the intake with the truck sitting for a few months? It hydrolocked and it got parked. Pulled the intake manifold off now and most of the intake holes into the head are clear full of coolant. Would it run back up into the intake or could i have another problem like a cracked intake manifold?
