Default smoke coming out of the breather, piston rings? ***video***

So i went tot the track with my cam/heads/intake firehawk a couple months ago and oil blew out of the rear main all over the back of the motor and smoke was pouring out of the breather and the exhaust. It was my second pass of the day and I thought my car was on fire after i got off of the track, there was smoke coming inside the car from all of the oil burning off. The car always smoked a little out the breather, but the track just made it get a lot worse. Do you guys have any suggestions on what this could be besides the piston rings, thats what I think it is but I wanted to see if there was anything else it could possibly be. thanks

Piston rings blow-by is the only thing that come to mind. Have a compression check done on all the cylinders, that'll tell where the problem is.

Puffing is no good, I would guess rings going bad in one or two cylinders.

Do a leak down test to confirm it

Do a leak down, something is broken. Maybe you broke a ring or ring land.

Compression test is very easy. Rent the tool from autozone, it doesn't take long at all.

Your looking at a rebuild. Your puffing smoke pretty hard from the oil fill spout. You probably have a good 3-4 rings beat. I went, and am going through the same thing still trying piece everything together.

I would NOT drive your car around anymore as your doing more damage to the cylinder walls which may not be recoverable (unless your just going straight to a ls3 block).

I was very lucky myself where I shut the car down and only had a small scratch on the side wall of 2 cylinders. Wiped out my cam and lifter though with scoring.

a leak down test is better .it will let you more then a compression test.
