Here's the toasted thrust bearing surface:

Here's the opposite thrust bearing surface. Notice how it's flat?

Here's the end of the crank after I smoothed it out:

Notice the oval shaped holes and the heat marks on the center of the pressure plate:

This plate sits in the pressure plate with a spring clip (not shown) and is pushed by a rod inside of the input shaft:

Rod inside the input shaft (I need to clean the bellhousing, the rear main was spewing oil because of the floppy clutch assembly):

Damage on the back of that thrust plate. It was pressing against the bolts that were backed out so every time I pushed the clutch pedal I was smashing the crank straight into the thrust bearing.

You have bad luck with cars, your always fixing stuff!
Tough break man, looks like you got it covered! Rule 1 of 3/S cruises: something always breaks.
Trans is in. Axles aren't bolted up. I'm debating just using my 6 month old timing belt so I can have the rest of the belts and intake put together, but knowing my luck it would fail and bend valves lol.
Shiny new pressure plate:

Dirty transmission:

looks like a good time to clean up under there.
It's a bit cleaner now. The trans really isn't as horrible as it looks since this end is exposed and gets road grime on it.
So this is why you flush an engine after spinning a bearing... No idea how much longer this would have lasted. Notice the oil holes aren't round anymore. These are from rod #3, the bearing that spun last time.

In other news... My car is on the ground, no leaks and it sounds a LOT smoother with the new crank and the clutch stuff taken care of.

Rod bearings are all at ~.06mm clearance (.12mm is the wear limit)
Main bearings are all between .05 and .06mm (.03-.08mm is ok for new parts)
Unfortunately I have no good way to verify the crankshaft end play, but the rods all tightened up to well under the axial wear limit. The block wasn't damaged in a way that affects how the thrust bearings sit, and the new crank's thrust surfaces looked good.
Now to break in the clutch :)
Pretty sure I had a leak from the oil pan into the bellhousing, so I pulled that and the rubber gasket was wet on both sides from oil. Awesome. RTV'd it up and letting it cure for a while before I dump the oil back in. I got a bit more metal crap flushed out into the pan from the thrust bearing crap. woo... :rolleyes:
Here's a video my brother took of the clutch assembly. The noise this was making was unbelievably bad. Some of the 3SPA members can attest, and it only got worse since they heard it.

doc, don't you wish the scirocco was available in the US? ;)
