weird turbo sound?
#11
well I checked the wastegate and I am able to move it with a good pull on the shaft(I assum from pretension) doesn't seem to be binding and other ideas maybe I missed a boost leak on the small hose from turbo to actuator ? I dunno im just throwing ideas out there does anyone know how truck would act with a bad mass airflow sensor?

hey guys anymore input on this issue any help would be great like I said earlier I hear the weird vaccum cleaner sound from exhaust seems to be underpowered when it happens I don't notice any smoke waste gate moves by hand ,no codes relating to a boost issue, didn't notice any big boost leaks when I checked turbo shaft play ok could it be a sensor of some sort or should I see codes with that

Other than checking the boots for leaks (tightening hose clamps), maybe for a rupture in one of the boots, as in "popped" or rupture in an area where it cant be seen. Possibly something rubbed/ rubbing on a boot causing a/ the possibe rupture. Also a possible boost leak, from compromised gasket, at the plenum cover (what your heater grid and intake elbow is bolted to). Turbo gasket leak Clogged Catalytic converter (if equipped), or somehow failed/ collapsed mufller, bent or damaged exhaust pipe causing excessive back pressure. im running out of ideas...........
just tossing them out there.
