Hey guys, I've been running a 034 vortex catch can on my BT setup for awhile and I've noticed that when the car heats up so does the piping for it and it tends to collapse under vacuum causing a bit of smoke occasionally at idle

Yes it's not my engine, its rebuilt. Possible its turbo but i doubt it.

So what do you guys reccomend for piping?
The can is a 1" inlet. So i can't really run threaded piping unless they make some sort of adapter.

I was considering just making a custom aluminum pipe to the crank from the catch can.

 

That would be pretty cool. Where do you have the plumbing routed? I'm running the same can with 1" parts store radiator hose and it works fine. Saw a guy on the zine who built his out of -an fittings and braided nylon hose, looks pretty ****

 

Well I have the stock j pipe off my 058 block, and it turn towards the front bumper, kind wraps around the throttle body piping and into my catch can.

It's one of the straightest routes i have unfortunately because of the pipe on the crank.

 

Nothin wrong with that, I was just making sure the plumbing wasn't laying on top of the compressor housing or something lol. You could switch to nylon/stainless braided line to keep it from collapsing, but at that diameter its not cheap...

 

Yeah that's what i'm thinking of doing.
And possibly buying this Block Breather Adapter, Audi/VW 1.8T - 034 MOTORSPORT

So i can remove that j pipe and have a straight run from the block to the catch can.

 

Ok so here's my setup, i bought nylon/ braided steel piping down at lowes and kind ghetto rigged it with some piping i had laying around but so far it hasn't collapsed and i doubt it will.
Maybe its just the placebo affect but my car feels tremendously better at idle especially and it feels happy with me now.
