So I started the 87 yesterday and found a collapsed lifter. Let it warm up till the fans came on and shut it off. So I started it today and the lifter had pumped up(or came unstuck). but as I was listening I though I heard another sound so I thought I would share and see if it was a sound that was normal or not. I can tend to be a little paranoid. Thanks for listening.

Let the motor run without the accessory belts (power steering, air pump, AC compressor, alternator). Sounds like a bearing giving up...

I will go out now and disconnect all the belts or use my stethoscope first on each to see if I can pinpoint it.

Sorry guys that I didn't think about the stethoscope before, but it looks like it may be the rebuilt air pump I got from Mark last spring. Darn thing only has about 300 miles on it. Guess Ill take it out and check it. Also put the stethoscope on all the other stuff and all is a quiet hum. Thank you for the quick responses. I will post back when confirmed Ok took the belt off before posting this, and now it sounds like:
