I bought a B7100HST awhile back and the guy i bought it from told me it was pushing water out of the radiator. I said ok, maybe just a head gasket . I started working on it today to see if it would crank. It will turn over but won't start. I decided to do a compression test on it. I took the intake manifold off to get the adapter in(I used the glow plug hole). When I cranked it over it shot water out where the intake was. Is that a head gasket or worse?
