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.

What happens when there is too much compression in a motor?

You will eventually blow a gasket or worse destroy a major seal. Also you can make the engine knock if you don't put high enough octane in, the higher the compression usually means the higher the octane you need, unless you have high compression from a supercharger or turbo, then it is not as necessary. But if you have knocking it means the gasoline engine is running like a diesel, which can destroy an engine if it happens for long enough. In a circumstance like that major components break, and not just seals and gaskets, you would likely have to replace the whole engine. If you decide to run high compression you must put heavier duty components in an engine. Good luck.
