Motor may be fried

Don't know what to say. Bummer...

That sucks Bobby. Keep us in the loop so we can advise you all the way through the process. LOL

That's odd.  Driving it a short distance with a broken belt shouldn't have done any real damage to it.  Did it over heat or was it over heated prior to the belt breaking?

Hopefully, it's not as serious as you think.  Hang in there. 

Do you have a screw in compression tester?  I'd do that first.  Just pull coil wire and do each spark plug and mark down cylinder and reading.  Then I'd remove the valve covers and look at push rods that popped loose or rockers that came loose.  You might see a valve stem that looks weird or doesn't move when you turn engine over with coil wire off.  Hopefully, just something needs tightening.  May the Force be with you.

4 hours waiting for the flat bed.  Got it home.  Drained the oil.  It looked pretty cloudy and dark.  I think I am going to drop the engine, transfer some stuff over to the old 1915 and put that back in so my wife will can at least drive it.  After that, I will start to tear it done and examine it closer.  

Slow down.  Deep breath. 

Compression test? Is the fan hitting something? What caused the belt failure? What do you mean it doesn't sound right? Slow down.

You have like 30 arm chair mechanics here to help.

Could the fan have partially come apart?  That would certainly cause some ominous noises without affecting the integrity of the engine.

Lane, good point.  Perhaps the fan belt was too tight and the alternator bearing(s) froze causing the belt to go.  New belt turns it but with noise/interference.  Could run sans belt and see if sound disappears.

Before I put he new belt on I spun the alternator.  It spun freely and there was no noise.  It seems fine.  The motor does fire up and runs.  It responds the throttle, but there is a definite clanking noise that was not present before.  Should I put some new oil in it and fire it put to record the sounds and post so you guys can hear it?  I am not sure what to do?

Ted, Lane, and Greg have a good point; take the belt off and spin the alternator. If that's good then reach around and check that the fan isn't loose- it's a long shot, considering the circumstances, but the center hole does sometimes wear (it works fine for stock applications, but for higher rpm's and the speeds we can make it accelerate and decelerate it could use a more solid connection).

Start with pulling the valve covers and inspecting the valve train. Good luck. Al

PS- Maybe go on Youtube and listen to a VW engine with a rod knocking and see if it's the same noise you heard?

Some information about the alternator could help to diagnose.

What brand of alternator? How many miles on the alternator?

With the belt removed, is there any play or wobble in the alternator shaft? Worn alternator bearings might cause these symptoms - and are more suspect since the problem started when the belt broke.

And while we're at it, what can you tell us about the engine - who built it, how many miles, is it gluten-free?

I was adjusting valves on VW engine one time and found one was way out of adjustment - turns out valve stem was stretching and about to have the valve head break off.  Often the stock rocker assembly breaks down and shifts too.  There are nice solid rocker shaft kits available.  Once removing the valve cover you could very well find a broken half of a wavy washer or a 13 mm nut sitting there.

So many possibilities.  Fan/alternator spins,check for play forward and back at the shaft.  Check your alternator pulley, many aftermarket ones crack at the hub. One should never drive it without a belt.  You can drive them without a oil cooler but they won't last very long with out a fan belt. 

Does the motor turn over ok by hand??

don't you just love all the we advice from all us back yard mechanics��

Ok Doctors:

Attached is a sound clip of the motor running.  Let me know what you think

I would disconnect the van belt and try spinning the alternator by hand because the question I have is why the belt parted ways unless of course the belt was old. You might find that with the belt off and the engine running (short duration of course) would the noise still be there.

Is it possible that the sound is the fan hitting the fan shroud?  If the alternator stand is broken that might cause the belt to break and the alternator to tip and the fan to hit the shroud (or something in that chain).  If you take off the belt, the alternator and cooling fan will not spin.  This would be a quick test.

I don't hear any obvious rod knock or weird valve train noise. Have you tried starting it up without the alternator belt on it? Only run it for a short time, and after it's cooled down for a while with the engine lid up.

Stethoscope.

Or a piece of 1/4" wooden dowel held fast in your teeth (molars on one side of the mouth) with the far end of the dowel touched against whatever you want to hear. You'll hear things by bone conduction.

Stethoscopes are rare and over-rated. Wooden dowels are ubiquitous. And they work. Try it! (No, it won't be too loud, and you'll hear so much that you'll have to concentrate

I would like to hear the engine run without a fan belt, too. You can run for a minute or two+ without one. I'm also wondering if the alternator pulley was put on slightly cocked (the pulley, not the installer guy....). If it was, it may not wobble, BUT being slightly cocked might make the fan belt ride up and down on the pulley and it will make a strange rumble/rattle sound.
