Heeelllllppppp? Service center isn't much help

K so i brought my car in like 3 weeks ago because i thought i had a blown diverter valve. They repalced it but the car still whistles/screams at high rpm's. So i brought the car back in today and i was told they did a pressure test and that there were no leaks. They told me that because my car has increased pressure that the diverter valve may not be able to handle it and its always gonna do that. I have a REVO chip and my service rep knows it and is cool about that part. But my car never whistled prior to about a month ago and i have ahd the chip for almost a year and a half. I said maybe the new diverter valve is defective so they are trying another one. Any suggestions?

An aftermarket diverter valve that doesn't have a rubber diaphragm.

Sounds like it might be your PCV valve. Is there oil on the top of your engine?

[lak2881]

No but there was like 2 months ago. They told me one of the valve cpas or some crap like that cracked. SOme plastice piece.

Well they just replaced both valves apprently there are 2 of them and the car is still doing it. Maybe i gotta try an aftermarket one. Like the forge.
