Catch Can problems

[Boosted Supra]

Recently the guys at E-Shift worked on my car, they installed a catch can, as you can see the valve covers vents are going to the catch can and at the bottom of the catch can, it's getting it's vacuum source from the intake pipe. I spoke to a bunch of Supra owners at the NE2K7 and they mentioned to me that it's hooked up wrong. With the vacuum source at the bottom, it's just sucking the oil right back in.

Before on my old setup (no catch can, just hooked up stock), I was not shooting any blue smoke on decel. Ever since the catch can has been installed, it's been shooting blue smoke. The guys at the supra meet mentioned that I should just disconnect the vacuum source and run the car like that, I did just that. Later today I went for a photo shoot, as I opened the engine bay, I saw oil on the catch can. After inspecting the catch can, the oil was around the catch can seal where the alan screws are holding it down.

My question is, what could've caused this? I passed all compression tests and leak down tests. Could it be a faulty catch can or install? Or is this a blow by problem? Let me know, thanks.

PS. Sorry for not showing my engine bay, don't want anyone to see it just yet.

Looks improperly hooked up. Pulling oil directly from the bottom of the tank into the intake. Looks like whoever installed it is an idiot (or has no idea how they work).

i do like ur car alot, i was the blue mkIII that was sorta next to you, yes it is hooked up wrong the bottom should be plugged and is used only to drain the can, correct me if i'm wrong anyone, but thats how mine is setup

hmmmm, didn't know your can was unbaffled.

easy fix- flip the can and add some baffling.

Thanks for the all info guys. I'm thinking of totally eliminating that catch can totally and using my filtered can from MVP. What do you think?

Adam - We were trying to flip it at the meet but the bracket was preventing us, so we just disconnected the vacuum source.

Viper92086 - thanks for the compliment, I was also checking out your car at the meet. Kinda sucks that I didn't meet ya, next time. Take care

If you flip the can, oil would collect in all the low points in the inlet hose.. not sure if that would make a seal, and not give ventilation.. may be make it horizontal? so, it works as a horizontal drum? still need a drain to drain oil out when half way or some..

Thats why we pay the shops the big bucks...

Update:

Installed MVP filtered catch can and no more blue smoke, problem fixed.
