Alright so i recently changed my rod bearing and coil pack to a used msd and replaced my valve cover gasket. i noticed I'm still leaking oil from the back of the seal I'm fixing that problem tmr,, but after getting it back on the road i noticed this weird sound coming from the front starting at about 2500 RPMS and gradually get louder as i accl this only happens in motion at a stand still i can hit 7000 RPMS and no sound at all ???? best way to say it sounds is if you blow up a balloon and let the air out while pulling the sides of the opening that wining sound is exactly what it sounds like... what is this ??? its very loud ,,,,,

Check your turbo for shaft play and check for boost leaks. Either you have a boost leak or your turbo is about to grenade, most likely.
The Talon I just bought had a shot turbo, and I was driving it a little bit while saving up to do a bunch of stuff at once, was fine to drive around at first, was just burning oil, but then I had to stop because the turbo started making some really unnerving noises and I didn't want to add engine rebuild to the list when it inevitably would have grenaded.

Also it was missing some pieces from the compressor blades, idk if that was causing the noise, or the bearing hating life was, but it was not a good sound...

I highly doubt it a turbo deal because it only makes the sound while moving,,,,

I promise you it's the turbo. It only does it while moving because that's when its actually spinning fast, has engine load, and is building boost. Either your turbo is about to grenade or you have a boost leak, I would bet my paycheck on it, what you are describing is exactly the characteristic of this type of issue. Turbo's don't do much at idle.
