Someone's been busy!
Here's what the engine looked like when I last saw it...

Nice clean-up there, as PorKen shows from the before shot!
That gear looks very worn but oddly in that it is shiny all over but without visible dishing or edge sharpening of the teeth. I sure can't see any. From what I have seen the dishing/sharpening appears before all the anodization is gone. It's almost like it was hand polished. There may be dishing on the tooth above the main reflection. I'll have to see if I kept a really bad one and shoot a photo.
Interestingly, someone was selling polished cam gears on eBay which on the face of it is a dumb idea.

Bill,
No dishing or sharp edges on the gear. Maybe this is what a 'normally' worn cam gear looks like at 72K ? The old belt was right in the middle of the Kempf Tool before I removed it.
How much were they getting for those 'modified' gears on e bay?

Wow, I don't remember it looking that bad. Maybe I should wear a respirator while cleaning...

Yes, I suppose the wear patterns I have seen have all been from overtensioning. The wear is central and deeper as opposed to the general loss of annodization you have with no deep wear. The driver side gear, nearest the tensioner, is the one that wears most. Don't recall what the polished gears sold for. Pretty stupid if someone bought them.
Let us know when the car goes VOOOM again.
