need help: my sc smokes dont know why.
I blew my engine about 6 months a go and i replaced it with a japanese 2jzge. But now when the car is cool and you turn it on it smokes a mixture of gas and coolant for about 2 min till the engine warms up and then its fine. I took it to a mechanic and performed a radiator compression test and cylinder compression test and every thing was perfect. they told me it could be from intake gaskets and i replaced all the intake gaskets and it still does the same thing.
if anyone has a solution to this problem i would appreciate your help.

gas and coolant?
leakdown tell you more than a compression i just learned, but they're more expensive, and if all the compressions were good, i'd say u're fine there anyways. . .
if you mean oil instead of coolant, on startup it's valve seals.
something taking a while till heat up sounds more like a cat problem or some expanding seal(but all the stuff will expand with increased heat).
wait, you do mean smoke out of the exhaust, right?

How are you determining that the smoke is gas and coolant? What color is the smoke? What are your specs? It will help us help you if we get a better idea of your setup.
It does sound like valve stem seals if it goes away after the car warms up. Its a common problem with 2jz's.

White smoke is usually a blown head gasket, black smoke is burning oil and usually bad rings, yellow and or pink smoke and your really screwed? 
Could be tuning and or bad ECU reads. Maybe something else. tough too say...Good luck......
