Hello All,
I own a '96 Contour SE with 52,000 miles. It's experiencing a massive build up of pressure in the cooling system. As soon as I start it the coolant level in the expansion tank rises about an inch, and the hoses get really hard. They feel as if they are going to expolde. I performed a compression test and five cylinders had 150psi. One cylinder had 125psi. No coolant was leaking out of that cylinder. Also no coolant was evident out of the exhaust. The car will overheat in about twenty minutes while in neutral. No heat also.
I removed the spark plug out of the weak cylinder and still had a pressure build-up. Besides a damaged head gasket, what could be the problem???
Thanks, Jay
