I have a 1995 Pontiac Grand Am with the Quad 4 motor. The car recently had the water pump go out on it and of course the coolant got into the oil and created quite the mess. The water pump, head gasket, ect. Has been replaced. The motor is now making a ruckus that appears to be coming from the valve train and some of the lifters appeared to be plugged up. It was suggested to me by a mechanic that the oil passages could still be plugged up and there wasn't any oil getting up to the valves. Is there anything I can put into the crankcase like GUNK to unplug the passages or do I have to take it all apart?
Thanks
