bailey dump valve

[nottsgreent5]

evening all bit of a strange one but im getting ruff tick over when ive come off the gas and onto the brakes prob makes it worse being a auto preasure tested turbo and pipes only very slight leak i could find was the dump valve bubbling slightly from the seal and under high boost ie. around 1.2 bar it screaches very loud is this the sign of a poorly valve lol

Im running a forge one. I had a bailey one on but was doing similar to what you describe so swopped them over and had no bother with the forge one.
