My smog pump is making a loud whinny noise, can this be the signs of it staring to go bad??????
Please let me know so I can go buy a new one. Thank you for any of your views on this in advance!

Yes

It sounds like a nother dead smog pump. They will whine and wheez when they are dying. It is only a matter of time before it seizes up. Did you dissconnect the AIR from it without removing the pump? If so that is the cause. No big deal really.
