A replacement head gasket is pretty cheap, however the engine has to be taken apart to fit it so there's a lot of labour involved.
Sorry to be the bearer of ill tidings
Before you get too carried away the cap would only blow off if it wasn't fitted properly but if you mean it is blowing out coolant then that's different. Also don't confuse normal exhaust condensation with a leaking head gasket. Check out the simply things first and have a pressure test before whipping the head off.
Thank you guys for the information, I have been out, checked, there is no water in the oil, there is no oil in the coolent, the coolent is blue colour, water coming out of exhaust is clear. Could it be the gasket has broken through wear and tear, or could it be something else? Coz I don't want to strip down the engine to find gasket is ok! Yet, water is getting into exhaust, don't want to run car in case of severe problem.
