Cracked Head?

[hodged]

I bought a 1993 GS 300 with 150K miles on it in February for $1500. Rode rough - but could tell the engine was strong. I put it straight in the shop. The replaced spark plugs, wires, rotar, distributer cap, air filter, and fuel filter. Ran smooth and strong afterwards. Drove to son's basketball game about 30 miles from home...car ran hot. Notice gurgling sound. Took to radiator shop. The said that they could not find no leaks...air pockets. They pumped air out of radiator...I replaced radiator cap with aftermarket from autozone. Car ran fine...never got hot again. Have put about 500 miles on car since then. Friday, driving and heard gurgling noise again. Open radiator to tap off with water...water came up like a volcano...but temp guage did not indicate it was hot. Water went everywhere. I replaced the cap and drove about 5 miles....car started to run rough like when I purchased it. I took off two spark plugs...noticed water in there, dryed and replaced. Ran a little better, but not much. Any ideals?

Probably the water around the spark plugs was from you opening the rad cap.

My idea would be to have the cooling system pressure tested - it sounds like a head gasket leak to me, and probably not the head itself.

Was there water around the base of the spark plug or was there water present (at one point) on that spark plug? Water on the tip of the spark plug would leave that plug clean and dry.
