Oil in throttle body

I was doing some pulls in my car and i checked my intake amd it was full of oil. I noticed that it happens in track mode when i redline it. Mods are aed tune and jlt intake. Any suggestions what it can be?

1/2 a quart???? THAT is a lot of oil! Is the car smoking at all out the back?

No, no smoke at all and runs good. And it only happens with the removed rev limiter with the tune. When stock no oil comes out.

There is no PCV check valve in the drivers side line because that is the "fresh air" line. Sounds like at high RPM there is too much crankcase pressure and vapors are back flowing through the fresh air line and into the intake.

You can get a PCV catch-can for both sides of the system (passenger and driver's side hoses).

Also make sure your oil level isn't over full.
