You're pulling too much vacuum on the crankcase and its actually drawing air into the engine through the crank seal. That is the squeal you hear. Remove all of your catch cans and PCV system back to stock.

Don't put catch cans on STOCK cars.
Thank you for the much needed advice. Originally i put the cans on to limit the amount of oil i was finding on the MAF and in the Turbo inlet. Unfortunately I guess I learned the hard way. I put the stock tubing on and removed the cans. so far so good.

again, I appreciate everyone's help, and time responding back.
