Reverse compression I have never heard of. It might not have any compression because either the vavles are damaged or the rings are really worn or the valve stem seals are bad. This would allow some fuel into the oil, but if you actually see a visible amount of fuel, that is a big problem. I am attaching a diagnostic explaining what to look for when fuel systems go bad. If the exhaust smokes, this is probably going to help you. Just follow the link below;
