Working on a friend's T-Bird - Rattling

Ok, so a friend of mine from work bought a T-bird a while back, he drove it once and it overheated.  Apparently the radiator blew on it.

He replaced the radiator and so on.. but it didn't fix the overheating.  I took a look and fixed the overheating problem which was a crushed heater pipe. 

But the car has a knock or a rattling sound coming from it.  It almost sounds like something rattling around in the engine bay like a pulley because sometimes it squeaks too. 

Anyway, here's the two videos I took, can anyone identify the sound of it?  I'm hoping not rod knock, but you never can tell.  This car does have 220,000 miles on it.

Also, it's a 92 3.8 obviously.  How do you pull the codes on this thing?  It comes up once in awhile.

Two videos here ---

http://www.cougarnuts.com/MVI_0589.AVI (3.70MB)

Both videos are very small, but I just took them for the sound.

Thanks for any help ahead of time.

That sounds EXACTLY like my probe gt when it spun a rod bearing.  Check with others though.  I'm about 80 percent positive.  Try to get information on how a thrown rod would sound as far as consistancy/repetiveness.  Do an oil change and look for shavings.

Take the belt off and run it to eliminate all the belt driven stuff.

Sounds like a rod. Valves would make more of a ticking sound. It's gotta be a rod. It's knocking like an SOB.

You, sounds like a rod.  Probably towards the back (those like to go first on 5.0's as well as 3.8's)

Well thanks everyone, but I'm done working on it.  He's looking for a different car right now.  Car isn't worth as much as how much it would cost to fix it.

Thanks all.
