Like yours, a puff of blue smoke when first getting on it after sitting for a few days.

Being that it is a '90, I was aware of the fact there was no primary valve guide seal on the primary valve. But, Marc Haibeck machined the primary guide to accept those seals (done when I had the heads off for porting - 91+ models came with seals on both valves).

Anywayz... new gaskets (Jerrys Gaskets) and some BLUE LOCTITE thread adhesive applied to the IH bolts (AND the same treatment for the windage cover too) stopped the oil seepage/smoke issue.

Thanks, Paul!
