Need Help ASAP with STS
I have a 02 SS M6 stock bottom end with a T 67 STS 42 lb injectors 255 pump and meth.Put Predator STS tune in the car and went to the dyno today to have it tuned with HP tuner.When we turned the boost to 7 lbs the car started shooting white smoke from the exhaust and then the back of the engine bay around the intake.We shut it off and then looked to see if we could find a leak somewhere in the back of the motor and then the smoke disappeared.We started the car again and now the white smoke was coming out of the front of the intake passenger side and there was oil around the front of the intake manifold.We opened the oil filler cap and the white smoke was coming out of there as well.I have an oil return line going into the valve cover.The tuner said he thought the car broke a ring or knocked a hole in the piston.So he stopped the tuning and took it off the dyno.After letting the car cool down I drove the car home easy about a 100 miles with no problems as far as oil pressure or overheating or strange noises coming from the engine.Car felt like there was no decline in power levels.Car felt like there was an intermittent miss at idle only.What I am trying to figure out is if the engine had a bad ring or piston wouldn't it make noise or overheat or have low oil pressure.Anybody out there who is knowledgeable about STS turbos please give me what you think my problem is and if the STS turbo might have cause the problem and how I could go about step by step diagonising the problem.Could the problem be bad vaccum,bad plug or wires or bad crankcase ventilation solenoid valve.It seems like the crankcase pressure was to high and that is why the white smoke was coming out of the filler cap.Anyhow I am not a wrench and know nothing about cars and would like an opinion as to what you think my problem is.The tuner made it sound like I would have to get new pistons etc.Any help asap would be appreciated. Thanks.

Seen a STS car do that before when the transistor for the oil pump went out. The Oil pump to the turbo failed and that was the result... I would PM Bob with EPP or Billy (I think his screen name is TRTurbo)

Good Luck. I know that's no help but every problem I've attempted to attribute to the STS was just my car mechanical problems.
I'd follow Longrange's suggestions. I've never really talked to him but he seems like the STS champ around here.

Make sure the switch valve is hooked up right and not boosting the crank case.
Alot of times you can have a broken ring or ring land and the car will not make noise.
Check on cold start and see if there is any noise. If there is and there normally is'nt, then chances are it is a ring/ringland.
You can also check your plugs and see if there is any damage and check for oil on them.
Feel free to give me a call if you want.

Just to let you know FlexTech does allow small orders apparently......Thank you an extremely large amount for the time you spent a few days ago getting me those 2.75" to 3.5" couplers man, you've gone above and beyond for the orders I've placed.

When I cracked my ringland/ring it did almost the exact same thing, except it was only smoking from the oil filler cap when the cap was opened. And TRT is right, almost no noise at all and the car ran fine on my trip home and at idle.

The switch valve should be grounded to the eyelet in the water pump.
One hose from the dual outlet side closest to the metal body to the throttle body. Single side outlet to the opening in the valve cover. Last opening should be for the filter.

the sts pcv system solution pretty much doesn't work in most cases from what I have seen.
redo your pcv with a catch can per the many examples on this site and see if that fixes your issue. if not you may have toasted a ring or two.
