Yeah.. I cleaned my radiator, replaced the radiator head and replaced the water pump few months back. But the issue is still there. after about 100km drive, the water level in the res tank drops in about 2 inches. My cap presure is 0.9. First I suspect it was the gasket, but my mech checked and told the gasket is fine. May be I must get a 1.1 bar cap. Also I am running on water since because of this, can that do some extra damage to the engine?
Cheers..
