Check everything again, water pump , hoses, header tank etc when engine up to heat. If from head gasket in to bore when system up to pressure rather than oilway water will go from piston to exhaust without oil in water or vice versa. Check for steamy exhaust or misfire and plugs to see if any discoloured. Bad leak in to bore will damage the engine as water not compressible. Heater matrix only other area water will be circulating. Can try varouse brands of leak stopper which you put in rad but normally a short tem fix that will gum up the works.

Yes, just me by the replies assuming you are talking 93-97 2.2
