Whites smoke = blown head gasket?
Hey, If you see white smoke under the oil cap, and white smoke coming out of the exhaust with a bitter smell, is that a blown head gasket? Oils is leaking from around the oil cap, but I havn't seen a blueish tint to the smoke that the car is blowing out... any thoughts on the subject would be greatly apreciated..

White smoke usually means a blown headgasket. It is usually followed by a rough idle, and a diffulcty or inability to start because of a lack of compression.

If the white smoke is very thin and dissapears from the exhaust tip rapidly them is mostlikely a blown head gasket and the smoke is coming from the antifreeze/water.
If the smoke is also white but much thicker followed by oil residue on the exhaust mostlikely could be bad turbo seals.

The most common symtom of a blown head gasket on a 4G63 is for the coolant to be pushed out of the engine and the engine overheating. It sounds like you have excessive pressure in the crankcase. This will push oil out through any path it can find.
This could be due to a plugged PCV valve, plugged vent line or broken rings.

Has anyone detailed all of the likely causes of blowing a headgasket on a 4g63? I know retarded timing can cause it. Any others?

I dont know if I have that problem. I dont get any white smoke from the engine or the exhaust, but my car does overheat when I am idling for too long and I have to refill the coolant every few weeks. When the fan kicks in, I can smell the coolant. I've replaced the coolant pipes as well as the water pump, but I still loose coolant every couple of weeks. My car has been idling kind of rough these couple of days. I got a check engine light code P0335 and p0340. The meaning of those codes are the crankshaft positon sensor failed and misfiring.
If its really a blown gasket, would that be covered under the engine warranty? I am over the mileage for the bumper and bumper warranty. Anyone know how much it would cost for reparing a blown gasket.

It shouldn't be all that much to replace a head gasket on these cars, its the same amount of work as head studs, and those are done for pretty cheap.
Have you been running high boost? If your still pretty much stock you might be able to get it warranty.
