If you lost engine compression do you need to replace the motor and where can you buy a good running motor in the Detroit area?

loosing compression does not mean you have to get a new motor it can just mean u have a blown head gasket if its an old car

If compression is lost on only a few cylinders, then check the head gaskets. If compression is lost on all cylinders, check for a worn or broken timing chain.
