Hey guys, So I'm going with a mate tomorrow to go look at an EP and the seller says that it's using water but it's driving fine. What could be the potential causes and the cost of repair? I'm guessing there may be a split rad pipe or a leaky rad but these would be obvious to spot? Maybe head gasket or a crack in the head around the exhaust mani studs? Somebody has also mentioned it may have something to do with the thermostat? I don't believe the car has been compression tested.. Thanks Amjad
