Oil smoke out exhaust after decel in gear
Anyone dealt with this?
When you run the car and leave the car in gear and let it decal in gear, when you crack the gas open it lets a good puff of blue smoke out of the exhaust.
Car has dual catch cans on it.
It has no engine issues, doesn't really use oil. Car runs hard, made 399 rwhp with headers, catless X pipe, intake and tune...car is strong.
It's pulling in oil from somewhere on decal, my Camaro also did this on track, just not near as bad.
Any thoughts?

Sounds like intake valve seals or intake guides. Not saying that's the cause, but typically with the throttle closed on decel you'd see a puff of blue smoke when you open the throttle again. What engine?

Not a lot of miles to expect guides to be worn...don't know how many of them are on the track. IMHO, not a big issue if it puffs a little smoke when you get back on the power AS LONG AS it's not consuming a large amount of oil.
Valve seals are pretty easy and cheap to change. Before I started tracking my C5Z, I changed the valve springs and valve seals. Might want to consider the same service depending on how much time are on the valve springs.
I added some info to this post...part numbers and pics.
