I'm parting out a r53 and it had a clutch with 20k on it. Is it worth anything? Is there anything else of value on this block?

 

You could sell it, although imo 20k miles on a clutch is all relative depending on how the car was driven prior. Quite honestly though, I don't think you'd get much out of it personally, and unless someone was really strapped for cash, they would likely just buy a brand new clutch kit and be done with it.

As far as the rest of the block in terms of value, you might be able to turn the block into a coffee table with a glass top if you're feeling creative. If that is not an option, you could sell just the block itself, and get some money out of it. I'm sure someone somewhere has a blown motor, and may want a used block they could use.

 

Probably not the clutch, they are a wear item and they aren't that expensive relative to the labor to put them in.

On the other hand, the flywheel is probably worth selling / buying. If it's the original dual mass flywheel, and it was new when the clutch was previously replaced, and it hasn't sat around rusting, it is probably still in perfect shape. If it looked good and smooth, and only had 20k miles, I wouldn't hesitate to reuse that again. That's a few hundred bucks new. I actually did that when a mechanic screwed up my previous clutch job (they put the clutch master cylinder on the wrong side of the mounting bracket, so the clutch wore out in about 15k miles, because it only had a fraction of the travel it should have had). So I got a new clutch disk, took the whole thing apart, made sure the flywheel was still in good shape (it was, the mistake meant the rivets couldn't get anywhere near the flywheel), and reused it.

So if you took off the bolts, flywheel, clutch, and spring plate, put bubble wrap around the flywheel, and threw it all in a box for somebody doing a clutch replacement, that would probably be worth $75 shipped to somebody doing their own clutch replacement. They could use the flywheel, and have spares for the bolts if any are stripped or in bad shape.

If they reused the flywheel on the previous clutch job (a bad idea given the labor

 

Depending on how the clutch, pressure plate, and flywheel look... you MIGHT get $100 for all three. But, it depends on how much you wanna deal with cheap people -- who would be your primary customer base for used clutch parts.
