Remove all the spark plugs. Blow some compressed air into a cylinder through the spark plug hole (set the valves to the closed position for each cylinder that you test). A rubber-tipped air blow gun that covers the entire spark plug hole works best for this test, or improvise.
If air comes out of the neighboring spark plug hole, there's a good chance that it's a blown head gasket (like what Tom said). If a lot of air comes out of the oil fill tube, then a hole in the piston is possible. If air rushes to the intake or exhaust manifolds, then its a burned or sticking valve.
If your son-in-law did cause this problem, and he is still of this Earth, then you sir are a much better man than I.

also remove the radiator cap - if water shoots out the headgasket is bad. Do this test FIRST before removing the head. Also make sure its in 3rd gear and parking brake fully set. And make sure engine is TDC on piston 3 and then 4 (or vice versa - as stated above you want both valves fully closed.)
