That will still cause issues. The intake is often running at 24-26 inches of mercury, while the AOS is running at 5 inches of water vacuum. With one inch of mercury running at about 14 inches of water, the intake vacuum is many, many times the vacuum the that the AOS supplies, and just as too much pressure can blow out oil seals, too much vacuum can suck them in.
