Massive smoke-986S

2003 S with 130K miles.... smokes like blown AOS only when accelerating hard going up hill. AOS is new and checks OK with manometer. I suspect failed scavenger pump and would love to hear thoughts from the gang. There are no strange noises and the car runs great with normally expected power and does not smoke except as noted above. Is it likely that the scavenger pump is just worn out? Do they in fact actually wear out? Any other ideas?

When the problem is the AOS, the intake gets coated with oil. Clean the intake, run it and see if the intake is coated. It's possible that your new AOS is bad. That's not common but it's easy to test.
