Is it possible to have a blown head gasket without having any water in the oil........Its blowing water out of the overflow and I've changed the thermostat, water pump and the radiator......and I've tried bleeding the air off and i get nothing but hot air....done that about 20 times........any other ideas?

 

Yes it is possible to have a bad head gasket without having water in the oil. Have you tried doing a compression test or leakdown??

 

Thats what happened to mine... part of the head gasket between the cylinder and a coolant passage gave. When I would get on it the overflow shot out coolant and white smoke out the exhaust.
