found the leak it was on the passenger side. not sure if it was a leak or not. these headers had holes where the air pump injectors were and i ground down the driverside awhile back.well yesterday i finally ground down the one one the passenger side and now it quit making the noise. BTW i had to grind down the inside of the tube where the plugs are.it sounds good now
