Default cant figure it out

I have a smoking problem,the car smoke a white/blue smoke only at idle. Never any other time, at WOT it doesnt smoke and hard deceltraion useing the gears, it donest smoke. I cant figure it out. The only thing that backs me think it a head gasket or a warped head is the loss in coolant and that the exhaust smells sweet. The car never over heat, It smoke and smoke and at idle only. Does this sound like a head gasket and a warped head??? I have never had this kinda of trouble before is it new to me. Input would be helpful thanxs

Sounds like a head gasket yes, but why do you think it's warped? The smoke at idle sounds like valve seals.

Don't know about that. I don't claim to be an expert by any means. However, are you sure there's smoke coming from the tailpipes and not steam? I had a friend that kept saying he had smoke coming out of this exhaust. So I went over there and he fired it up and by golly it wasn't smoke! It was steam and told him he needed a head gasket. How's oil consumption?

I just went through the same thing on mine it was both heasd gasket and warped heads however the head gasket is what was causing to smoke/steam.

yeah i just spent $2300 on my car for head gasket, head work, valve work, etc. I had the entire engine overhauled and reworked so that I don't run into the same problem at least for a while
