Default What kind of oil do you have in there?

When you say siren noise...you mean the turbos? It kinda sounds like it might be something else, if it subsides immediately.

I've had the same thing ever since I got the car. Nothing to do with turbos, check your pcv valve

Default not more then a week ago i had the car in cause white smoke was billowing out the back

they replaced a valve cover seal, cam tensioner seal, prop shaft seal... and this stopped the smoking? It makes no sense to me.. the smoke was coming out of the exhaust not smoking off the engine block. So im wondering wtf is going on now... Never once did a drop of oil hit the ground before all of this or i would have noticed in the garage. The car had where i left it when the tow truck picked it up. No place else...

should i have them pressure test? im not noticing any power issues... sigh

Default whatever the dealer put in it after the seal leaks... the sound is nothing more then a high pitch

siren noise.. i couldnt really hear it in the car.. my buddy on lunch walks up and hes like whats that noise? im like what noise i crack the window and i hear a constant high pitch sound that goes away less then a minute later. I've heard this sound once before the white billowing smoke.. but no more then twice now, this being the 2nd time today on lunch.

Default I had same issue. Went away after I replaced Hyperboost valves with 710Ns, tightened clamps and..

popped the air filter housing out to make sure that my K&N panel filter was seated correctly. The whistling noise went away after the tinkering.

The noise I was hearing was a subtle whistling sound from the passenger side of the car. This occured during startup and between 2500-3000 rmps in 1-2-3rd gears. I don't think it's turbo related, but then again, I don't really know much. I'm just weekend mechanic wanna-be. Hope this helps.
