Well your smoking might have stopped because of what you did..but whats causing the smoking??? sounds like a band-aid to a bigger problem..

I'm getting absolutely no smoking anymore at this point, but I suspect the air cleaner hat I'm using to get more hood clearance may be causing an air flow restriction at high rpm, which is causing higher than normal vacuum. This combined with too small of a baffle under the PCV valve may be the underlying issue.
