Decided to take my wastegate off my car since after so many years of work it got stuck open one day! Tought i give it some testing with a regulated compressed air. Connected the hose to the bottom nipple and as opened the air to around 10psi air strarted to leak right round the valve , out the exhuast chamber. As i continued to increase to 20psi air was getting out more and more. May i ask is it normal? Tought that a wastegate cannot leak from nowhere. Thanks
