Thank you everyone for the answers. Someone asked what the compression numbers are. Sadly, they are 15 lbs for each piston. It’s been sitting for a long time. My husband sprayed penetrating oil in there and it has been sitting overnight in hopes that if something is stuck it will free up. We are going to check again today (I will keep you all posted). We will then take it apart and check the head gasket. We know 15 lbs is not good but if all was well what compression number would be good?
