[DeTomaso] Fw: Bad head gasket question ?

[Will Demelo]

Your rad is not cooling the fluid enough. I think it's running too hot at 
230f with a 160 stat. The rad should be extremely hot to the touch. At least 
230 degrees if your gauge is reading 230.
I would also check that swirl tank cap again. The pressure is is exceeding 
the cap rating and allowing steam? out. There shouldn't be air or steam in 
the system.
