it should last between 150,000 and 200,000 miles... mine just went out at 155,000... the implications... depends on what happened... if it seizes... then you will create no boost... and you'll have excess back pressure... if the oil bushing goes out... it'll slip to an angle... and machine the inside of the housing... or it'll just disintigrate... best thing you can do to prevent this... is just use synthetic blend oil... unless its been brought up on full synthetic... I know it costs more... but its worth it... and don't go more than 3000 miles before an oil change... don't go with the dealer recommended 5000...
