Its better tat you get your car checked by a good mechanic.he'll be the right person to tell you what's wrong and would solve it.

 

You should pressure test the cooling system to make sure it's sealed up too. White smoke usually means coolant in the cylinders. If the pressure test shows you have a leak but there are no drips you could have a head gasket problem.

 

I am a decent mechanic and am confident enough to check over my own motor. I'm just stumped right now, the headgasket is new, coolant levels are fine, no signs of oil in coolant resivoir. Motor did amazing on the dyno strong pulls.

 

Anyone?

 

Cracked head leaking coolant into the intake or exhaust valves? Valve stem seals took a ****? Have you used a block checker on the motor yet to see if there is contaminants in the oil such as coolant or water? Sounds like a head issue, if you have good compression its probably not a head gasket, sounds like you might have a ****ed water jacket my friend, use a block tester and that should help you check out this problem.

Also do a leak down test on each cylinder, that might help you identify your problem.

Does the motor puff white when its cold and hot or just hot?

 

mainly when its hot. but it doesnt do it as much after i got it tuned. it still does it here and there.

 

Is there any head work done to the motor? It really sounds like you might have a crack in a water jacket on your exhaust side.

 

Saw this on a car at work the other day, the head gaskets toward the exhaust side of the heads were bad and the car would puff white smoke and ran kind of funny and stumbly, just like it sounds yours is doing now, my suggestion, replace head gasket and see if its better =] well a water pump and timing belt while you are in there.
