Yes, a blown head gasket can cause water to come out of your exhaust pipe. This occurs because the gasket failure allows coolant to leak into the combustion chamber, where it is then expelled through the exhaust system. You may also notice white smoke from the exhaust as the coolant is burned along with the fuel. It's important to address a blown head gasket promptly to prevent further engine damage.
