Never heard of this one. Doubt I'd even consider trying it too!

Have you ever proven that you are actually getting to much oil to the top? If so.. How? Did you run the motor with the valve covers off?

Or are you assuming that because the motor "burns" some oil and leaks some oil on the valve cover that you're pumping to much? I vaguely remember you've been chasing this for awhile. Is that correct?

If you're convinced that you're pushing to much oil to the top, swap the 2 bolts (1 on each side) that are specially tapered/narrowed to allow the oil to the rocker shaft. Use a standard bolt, grade 8, with the same measurements but without the narrowed area, go for a quick ride and see if the problems persist. Don't keep these in there permanently, unless you pull the valve covers and ensure there is oil flow.

I wouldn't be comfortable dropping metal parts to float per se... that just "feels wrong"... HTH
