I know air pumps naturally make some noise, but it sounds like a bearing in mine is turning totally dry (description of the noise, not sure the problem if there is one). Are these serviceable at all? I know it says no oiling, but would it help to?

You can take them apart,but really it is a pain in the ***.Stupid internal design.
Just get another one from somebody that eliminated their pump from the engine..they are dirt cheap!

Who's to say theirs would be any quieter?

You haven't seen the inside of one,have ya???..lol!
The thing has 3 vanes that actuated by centrifugal force.
The vanes are most likely rubbing corrosion on the inside of the Pump..hence the noise.
Really IF the pump has been operational,then it should be clean inside and run half decently.

It runs just fine, just noisy. Not a huge deal. If it's that complex I'll just forget about it, as it's 100% operational.

Take it off, wire the ports open. Then it's nice and quiet.

He has a TII, so the air pump plays no roll there. Plus, wiring auxiliary ports open kills low end torque anyway.

If TII, remove the pump and get a double alt. pulley/yoohoo belt.

OR

Go trade in your air pump for a reman. These things don't last forever. I had one spit its seals out into the ACV, which made it 1) useless 2) noisy as hell.

I still nee the pump to pass emissions and what not.

Who needs torque when these engines rev to the sky???????

Also OP get a corvette air pump.

Because wiring the ports open is for hacks. Fix the system properly or sell the car. There are too many jacked up FCs in circulation because the idiot owner starting ripping things off the engine without bothering to find out why they are there.

Wire them open if need be temporarily, but fix the source of the problem. And people who want to get moving from a stop without revving the engine and dumping the clutch appreciate torque.

Ok don't wire it open, take off the pump and get the pineapple sleeves, now you get your torque back!

crazy, i see them with over 200k miles regularly still working away without any issues. yet to see one fail.

RotaryRocket88

I think a bad check valve between the ACV and LIM (port air path) was allowing hot exhaust gases to get in, which led to its eventual demise. I replaced it at the same time.

or it was run without a filter for a period of time, that would wear the vanes relatively quickly. just like apex seals, once they wear to a point the seals fall out of the slots and get spit out the exhaust.

Only if it was done sometime before 2002, when I bought the car. This was in 2006.
