Its best if you dont use it as there is a high chance of further damage, but it all depends how bad it is gone. Slight gasket blows can leave car drivable for a while. If, when running it doesnt need topped up to often, i.e at least half hour, before it is reaching bottom of expansion tank, a compression test says only a slight drop in problem cylinder/cylinders, and it defo aint getting into the oil, you could probably risk it, but its a gamble, dont whatever you do let it run dry, or you will definetly be skimming your head or looking for a new one. Why dont you hire a towing dolly, and move it like that instead of risking it
