I would. The engine should still run. A cylinder leakage test will identify why the compression is low, if it really is. Causes include leaking exhaust valve, leaking intake valve, leaking head gasket, and worn piston rings. None of those require a new engine or a total rebuild. The first two don't include very much more labor than replacing head gaskets, which is common on many brands of engines.
