Default Smoke on the race track

Hi Everyone,

I am currently running an open PCV system. Breathers on both PCV valves and high temp silicone plugs on the ports of the valve cover and intake tube. Now the issue:

When I near 5k+ RPM in 4th and 5th gear on the race track, I start to smoke a good amount. This only happens in gears 4 & 5 as I near redline.

Anyone have any input to what is going on here? I do overfill a bit since I have a larger oil pan, but this happens even as my oil levels drop a bit. The flaggers black flag me once in a while which can throw off the flow of my session

Hard to tell exactly, but I am fairly certain it is the engine bay since I get the smoke in my cabin.

The PCV hose out the back of my valve cover with the breather on it is routed right over my headers.

More profound during high speed corner load (>100mph like turn 7 & 8 and Willow Springs International).

It wasn't smoking to much this past weekend and is dripping oil down my driver side, where I have the rear PCV valve hose with breather routed to.
