Brian. True, the vacuum pump in and of itself would not be the root cause of the lifter noise. HOWEVER, the vacuum pump places SIGNIFICANT additional load on the shaft thus causing faster wear. Of the three or four vacuum pump units i have witnessed the vacuum pump is rather ill fitting. The ill fitment contributes and even greater additional load on the shaft.
