Do You Guys/Gals no What this might be??
I'd look long and hard for a leak before blaming the engine, especially with the symptoms you describe. All it would take is a tiny leak in the radiator or a seeping hose. Also, try replacing the pressure cap. I found that mine wouldn't hold pressure at 30K.
If the head gasket is leaking into a cylinder then this is probably occurring when the engine is off but while there is still pressure in the cooling system. A mechanic with a bore scope should be able to see the deposits left by the evaporated antifreeze on top of a piston. I’ve never heard of a 4G63 that used antifreeze this way but there is always a first time for everything.
