[urq] exhaust turbine hitting housing???

[Brandon Rogers]

Tough to say....The first thing I would do is a pressure test - pressurize
the intake system to find any leaks - maybe that is what you are
hearing....?

good luck

hey guys, Just got the gold goat (83 urq) out of storage since the 4
runner's slave cylinder went out and it ain't the best. The car runs and
drives fine until boost, at about 5 - 7 psi of boost I have a sound like a
heat shield on a driveshaft dragging or a samurai sword being removed from
its sheath. It really sounds like the cartridge bearings are wobbling and
the vanes are hitting the housing. Is this possible? the car ran great and
made no noise previously pulling through all the boost range strong, no oil
smoke before or now...I have not had time to inspect further. thanks boomer
