Default Blue Smoke @ First Time WOT ONLY

I noticed yesterday that I do for sure burn blue smoke when I go WOT. However, it is only during the first WOT in a drive. I can go WOT after that first time and it will not happen again. That is untill I turn the car off for a long period of time and start up again. I did not burn any oil at the dyno, no blue smoke whatsoever. This confuses me. Any thoughts?

Maybe it'* that when you get to your top and the car richens the mixture like hell right at the top? Or is it blowing blue smoke the whole time you're on WOT? Like from low RPM'* to high RPM'*?

At the dyno they tested it in 2nd gear. I nailed it @35 mph for a hard 1st gear downshift when I got blue smoke. Yes, my car runs very rich, the dyno proves it but when it redlined the smoke was black not blue.

Leaky valve seals can slowly leak oil into the cylinders so that it is only noticable after the car has been sitting for a while, then it is gone till next time.

By long I mean long enough for the engine to cool down. Sorry, I drive a lot. 12 hours is a long time for me not to be driving. Tell me more about the throttle body gasket.
