Blue smoke, backfiring, rough idle

Oh hi everyone, taking bets here on what happened!

Blue smoke, probably burning/leaking oil pretty badly and randomly.

Almost got to work today and noticed my car idling really bad and stalled at a light. then noticed when i started it back up I smelled burning chemicals, noticed white/blue smoke everywhere. limped that last mile to work like a dumbass cause its 0 degrees out... SHIT! LOL. Oil level seems fine, coolant level seems fine, no codes, temp seems fine, i wasn't beating the car for the last few days; i drove it like a baby (maybe thats the problem??)

sooo fun!

a while back i DID find some milk at the bottom of my dipstick, which many chalk up to be some magic VW mystery due to cold weather, and i have been losing some oil lately, around 1/2 qt to a quart per ~2000 miles maybe?

Mods in link below, basically K04+Bolt ons, 50000 miles.
New tensioner 5000 ago
no signs of any issues prior to this morning, car is a champ that I drive responsibly.

^ yep!

Buddy gave me a reality check that my catch can was probably full and frozen causing a blockage of crankcase pressure! NOT GOOD!

Drained it, it was chock full up to the lines. Reinstalled it, will run the car for a while and see how it goes... hopefully didn't blow out my rear main.

Get rid of the CC, and just change out the PCV and do a valve cleaning (you'll still have to do it) every 50k miles.

+1 here if you have a Catch Can. I have heard this happening to folks.

Another CON to having a Catch Can. I would definitely pass on one.

I wouldn’t run a CC either unless it was a track car only! I would fit the newest revision PCV.

If the lines are thick and you empty it more regularly when its cold. There should not be an issue.

Why? If you keep poping PCV's then something is a miss and its not the PCV. Lots of folks here running Big Turbo's and BIG HP and dont have this problem.
