Mile high crankshaft in Denver has done a few for me. They do excellent work for a good price.

Thanks ,,the more info the better

why does the Buick crank need to be knurled? i don't think any other American engine built since the late 60's has had to have the knurl.

Factory came with a rear main rope seal..change to the wedge type is the reason I suspect

 

[SNOWBIRD]

After much research the knurling acts as a pump to pump away excess oil from seal ,but from looking at different cranks I have seen all kinds of knurling .....from fine lines that hardy lubricate seal .to deep grooves that the seal will ride on the tip of the lines to lub the seal which I believe is needed,,,know what is the proper way to set a knurl,should seal ride on lines
