Catch Can Setup Quick Help

Its not fitted in the car atm. It was fitted on my old car venting to atmo with the two lines from the intake and exhaust side going to the can and the other outlets blocked off. I want to run it recirculated here. The blue line replaces the filter and plumbs back into the intake pipe.

Will this work? My main concern is the suction side is too close to the two input breather lines so alot of oil might just go back up into the intake. I could jam something into the bottom of it to push all the mesh shit up. Should I just run atmo and be done with it? Maybe flip the can upside down, put a nipple in the drain hole and cut off and thread a bolt into the old nipple?

The picture is to scale and a little technical.

Lol @ the picture is to scale.

Its hard to avoid getting oil back into the intake. Even oil mist will build up on the pipework over time.

Are u trying to run it to the pcv valve on the inlet manifold?

Try to mount the can lower then where it breaths into the inlet. And run the hose up hill to the intake. This will stop any liquid oil running into the inlet.

It's been covered before - not more than 2 months ago, complete with pics.

1. Remove the hose between the left (passenger) rocker cover and the turbo inlet.

2. Run a hose from the left rocker cover to the catch can.

3. Run another hose from the catch can to the turbo inlet.

How simple is that?

To reduce the risk of oil fumes being carriewd over to the turbo - the general purpose of the catch can - fill the can with steel wool. This provides a surface to assist with getting the oil out of the air.

I'm leavin the pcv alone and just trying to do basically as above has posted but I don't get it. I think I need to flip my can as the points in the can are too close. This is the closest to stock setup but at least it will remove some of that gunk. Gonna be fun cleaning the oil out of the cooler setup.

I just want to ask, if I run the setup the way described above, is this for a sealed catch can? Ive got a catch can with a breather filter ontop and I have a feeling this will draw in unmetered air while connected back to the intake.

I can do the following:

Connect it with the filter in tact, intercepting the pipes as you've stated and see if it breaths in uncounted air

Block the filter with a blanker piece and connect it as advised above.

Connect intake side to one inlet on the can, exhaust side to the other then block the return on the exhaust side and plumb it back into the standard intake infront of the turbo.

Any suggestions?

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
