I have replaced the radiator, thermostat, and hoses. I have to fill the radiator with water every week. I have a closed deck JG bottom end.

Do you think it's the water pump or thermostat temprature switch?

 

did you bleed for air pockets?

 

So you're burning coolant? Are you sure the headgasket is sealing?

 

maybe a head gasket problem anyone else have a suggestion?

 

well what have you tried so far? Check compression. It probobly your headgasket. Remove the oil cap and look under it. If you see milk under it or white smoke from the exhaust, its the HG.

Check the head for warpage with a straight edge and feeler gauges.

 

What if it smokes from the oil breather? Had this problem on a friend's car, white smoke. I think he overboosted his car because I've found the tube from the wastegate to the turbo ripped. Could that be the head gasket too? I've checked for creamy oil, but none was found. Any help would be helpful.

Thanks,
Jay

 

Someone has to correct me if im wrong, but it could be the cracked valve guide? I think thats what its called. or even your pcv.

 

If your loosing coolant, and there are no leaks, there's only one place it goes- combustion chamber. Your head gasket is not sealing.

Been there, done that.
