There is white smoke from my exhaust, even at idle. I have replaced the headgasket, but the smoke is still there! What could it be?

 

and there wern't any signs of a crack on the head or block? if not, does the tail pipe smell of burnt coolent? is there any moisture coming out exhaust? and is your resevoir empty, if there isn't any coolent missing from your rad. or res. and oil is in it's place it sounds like it might be a fuel issue, does it smell rich?

 

lots of people mistake light blue smoke for white. Are you sure?
Are you losing coolant? If its not the gasket and you are losing coolant then you must have a crack that is letting water into the combustion chamber. The crack could be in the block or the intake side of the head. Fuel problems cause black smoke and is rarely mistaken for white water smoke.

 

when you did your headgasket, did you have your head milled and pressure checked?

 

check your plugs to see if they are all gunked up... if they are give em a good cleaning or replace them. Oil getting into the plugs could either be a cracked head, or crapped out rings. Unless you maybe put to much oil in, that could cause an overflow, and in turn bugger things up.

 

Synthetic oil will burn white.

 

if you replaced the head gasket did you get the block and head checked for warpage? if thats not the case i would start looking for a new block/head cause you probably got a crack somewhere

 

If it doesn't go away, then rings/ringlands
