I have the engine out (87 300D) and head off (blown head gasket and cracked head). I see a little surface rust in a couple spots in 2 different cylinders. I think I can clean it up with scotchbrite pads and then superfine (1200-1500 grit) aluminum oxide paper. It ran well except the head problem so I don't suspect any bottom end problems. I am considering pulling the pistons to hone the cylinders as an alternate to the local spot cleanup. I was wanting to get peoples experiences with both approaches. I did search the forum and got several hits, but was not able to discern views on these approaches.

Thanks,
Lee
