OK!
Brakes seem the same fine, on softness or loss of brake over time.
I might be crazy but it seems to come from the right side
replaced one bov a month+ ago, i will swap it with the other one and see if the noise changes.
the noise comes only under decent boost, im not sure the soap trick will work, but more so... are you saying suck the exhaust, plug one pipe and hose the bay down in 50 water/ 50 dish soap?
i'd love to do a smoke test. but i live in eugene where my dealership does not even know how a boost solenoid works, i may have to find a shop further out of town.
i had planned on solid hot pipes already because i think PLASTIC flexible parts that break down over time in a boosted vehicle are silly.
