OEM oil pump issue

[97gst_spyder]

Well for what it is worth this is how I solved my oil pump failures after destoying 4 pumps. Since I fabricate corian counter tops and some tops calls for a high gloss finish I decided to use this technique on my oil pump and oil pump gears to kind of smooth the surface finish. So far so good. I also swithched to amsoil high zinc 10w40 high performance oil. I had two oil pumps sitting in my shop one with helical gears and the other straight cut gears. I polished both pumps and both set of gears front and back face as well as shaft to a mirror finish and ended up installing the straight cut one into the car No more issues no oil leaks anywhere The place where I dynoed my car said that my dsm was the first that he has seen that has no oil residue anywhere on the engine. here are some pics of the polished product.

do you know if he is using the straight cut gears or helical gears?

I have the straight cut gears in my oem pump, but had the Helical gears in the Topline pump!
