Grinding Oil Return Channels

I started cleaning the rust out, and got carried away. I didn't want to do as extensive of a cleanup job as I did on the GSX, but still wanted to make improvements because of the kinds of oil-related problems it experienced. There's a method to this madness. It will make more sense once I get around to bolting the oil pan back on. The techniques in this video are things I had to do right now if I was going to do them at all. Some of them really needed to be done anyway. You really don't see people do these tricks on imports. Just because you don't see it, it doesn't mean it can't help. I hope you enjoyed the motor oil drag races in the middle of the video. They speak for the science behind this mod... without having to get all scientific. Those results speak clearly for themselves, and there's plenty of chances to get scientific as the Glyptal treatment of the GSX is completed. In this video... I used steel wire cup brushes for both an air DIY grinder, and a Dremel to remove the rust. I used a cone-shaped carbide double-cut burr to smooth the crankcase. I polished the crankcase with coarse and medium sanding rolls for both an air DIY grinder and a Dremel. I used a 1/4" ball carbide double-cut burr to grind the channel. I used a pack of Harbor Freight #95947 10-Piece Tube Brush Kit. http://www.harborfreight.com/10-piece...
