Heavy Heavy Smoke, checked everything I could think of....Please Help!!

[TurboDreamzGST]

So i got a 98 GST Spyder completely stock when this problem started happening...At idle i noticed some white smoke from the exhaust and as i drove it, the smoke started pouring out of the exhaust....the more throttle i gave it the more smoke poured out and i really didnt want to push it to boost because I was afraid of what might happen...so i ran a compression test and came up with 155 across all cylinders...so after checking out as much as I could i came to the conclusion that the turbo seal must be blown...so I went ahead and replaced the T-25 with a new Evo III 16G...well i JUST finished the job and low and behold the problem still persists....looks like a very very thick white smoke from the exhaust with not much blueish color honestly which leads me to believe that it is antifreeze that i'm burning but I noticed something very strange...my temperature gauge is just a hair higher than what it normally runs at and my overflow bottle is just continously filling up to the point where its almost about to overflow....any ideas on what in the world could be causing me all these headaches? This is my daily driver while I'm working and going to school so money is a little tight and time is of the essence on fixing this problem....please help guys!!

Also forgot to mention that my oil is not milky at all so it doesnt seem like theres any antifreeze in the oil

It sounds like you may be pushing coolant. While the car is cold pull the cover for your coolant then turn the car on and let it run for a bit. If there are any bubbles coming through then you probably need a new headgasket.

Otherwise thick smoke comes from a blocked or kinked turbo oil drain tube

You don't always get coolant and oil mixing when you blow the head gasket. This sounds like your problem.

Well since i just got done installing the new turbo about an hour ago, i know its not a kinked oil line and I had a feeling it was going to be a head gasket....any other tests i could do just to confirm that it is the head gasket? I mean i just dont want to go through everything to replace the head gasket to only find out that it wasnt a head gasket....kinda like what happened after i replaced the turbo

If your getting clouds of white smoke, coolant has to be entering the combustion chamber. The only way for that to happen is either a cracked head, or a blown head gasket. I'd lean more towards the head gasket being bad.

The only reason I'm unsure if it's a head gasket is because the smoke doesn't smell sweet like coolant does when it's being burned and because my compression was pretty high at 155 all the way across..what do u guys think?

Had a similar problem with mine. It happened more at idle. At idle there would be tons of white smoke; it would clear up a little as I was driving it. I replaced my valve stem seals and haven't seen white smoke since then. That was a year and a half ago.

Start off by pulling all the spark plugs. If any of them are extremely white on the electrode then that would be the suspect cylinder. If you want to be completely sure you can go to an auto parts store and buy a cylinder leak-down tester. You can actually measure how much each cylinder is leaking on its compression stroke and you can just go around to the intake, exhaust, oil fill on the valve cover, and the coolant fill and listen for air leaking to find where your leak is coming from. I imagine it is probably your head gasket as well as everyone else it seems like. So try that and let us know, good luck man.

Also the easiest and cheapest check would be to disconnect all your crankcase ventilation hoses and see if it goes away. Also remove the check valve from the back of the valvo cover. If the smoke goes away then you have excessive crankcase pressure from either blowby or from a lack of ventilation.
