$300 Cadillac Eldorado, quick head gasket check

Something to check out when buying a $300 Cadillac. A quick way to check for a blown head gasket. Anything is possible on a $300 car, but this one turned out to be ok. It even passed emissions and inspection after replacing the lower A frame and wheel. What a buy, but I didnt need it and I sold if for a good profit. I like old cars.
