My brother recently purchased a 2000 s4 with a blown timing belt. We have removed the heads and purchased new ones. Unfortunately, One valve broke and caused some scarring in one of the cylinders. I have considered using tig, filling, and grinding the pits, but I guess replacing the piston is the way to go...does anyone have a used piston for sale?

 

how much did he get the car for and how many miles were on it?
