In case anyone is interested in a catch can setup...

[430hps4]

I've been working on a setup for my 4.2 FSI Touareg for a couple weeks now. No real hurry on my part. Just a lil project I'm working on. If any of you V8 S5 owners have been considering something, and don't want to fork out $600!!! to BFI for their back ordered kit... here's something you can play around with...

Had ordered the BFI one and waited for it for about 6 months before I gave up, and then got an email saying they were discontinuing it. Had also made arrangements with them to just get the fittings, but they stopped emailing about those too. So, more or less did the same thing with the OEM hose. Mine had cracked, so I needed to do something anyway. I used a Mishimoto compact catch can, -8AN hose, -8AN fittings and some plastic couplers I found at Home Depot. Ground down one side of the coupler so that it was smooth and then epoxied the fittings into the ends the old hose. No leaks. Car runs noticeably different when there is a leak, as I found out. Thought I had pictures in my Flickr or my phone, but I guess I took them down. Car is in at the dealer right now, I will post some pics when I get it back.

Yeah, when I had contacted BFI about getting JUST the fittings... they gave me some crazy price. It was like $200 or something.

I get there isn't much demand. But how about creating a product at a fair price to get people interested? When you price things out so high... of course they aren't going to fly off the shelves!

So when you get the car back... post of some photos of what you put together. I'd be curious how your setup sits in the S5 vs the Touareg.

Ok, this is my setup.

Mishimoto Compact Catch Can, there's probably better. I had held one and looked at this in person, so for what I was going for I felt it would work.

-8AN Hose I opted for re-inforced, but it's not necessary. I just liked it for the extra stiffness it would provide.

-8AN 90 degree bend fitting and -8AN straight along with 2 -8AN to NPT fittings to hook up to the catch can

For the breather tube I used these http://www.sharkbite.com/product/reducing-couplings-3/ found at Home Depot.
I used 3/4" to 1/2" reducer, I believe. It has been a while since I did this. I ground down the barbs on the 3/4" side and then used epoxy to hold them in to the old breather fittings. It doesn't look the best, but it works and there are no leaks. If there is a leak, you will notice your car idling rougher than normal.

I used an inch wide piece of aluminum also found at Home Depot, used a bolt and washer already present and measure my catch can either 10" or 12" from that hole. I can't remember how far up I put it. But I didn't want the catch can to be lower than the valve cover opening. It's pretty close to even right now.









Feel free to ask me any questions.

I like it. The picky part of me would have gotten the 3-port can, plugged the incoming port that would be on the left (if facing the engine bay), that way your incoming line would be on the right, and the outgoing line would be in the middle. It would prevent the crossing over of the lines, and make them run side-by-side, making them look like they flow better.

But, that's just me being picky.

Where did you find the black/red fittings from?

And I'm confused about the Sharkbite fittings. Did you put the OEM Norma "male" fitting inside the ID of the Sharkbite? Then epoxied that??

Wasn't too concerned about where the lines were running, really. Just function. Fittings came from Jegs, can't remember if they were Jegs, Earl's or Russel at the moment.

Sharkbite coupler I ground down the barbs on the ¾" side and stuffed that inside the norma fitting. A little epoxy inside, to seal it up and then obviously some on the outside. Been like that for a few months now and it's held perfect. Line was already split in half so I figured I would give it a shot and it worked out in my favor.

what is the exact purpose of a catch can, i believe it has something to do with oil spray but unsure. and what benefits would come out of getting one? new to modding, well engine modding at least lol

If you search, you will find an endless list of threads related to catch cans and the FSI motors.

The FSI motor is prone to carbon build-up on the valves. In order to try and limit the amount of build-up, people install catch cans that help trap moisture and oil vapors, before they get recycled into the intake tract.

right but I've seen endless contradictions also so hence why I ask

Oh how time flys when you aren't focused on a project!

So had a tough time finding the right size metal fittings to go from the catch can to the braided lines. I finally found some coolant pipe barbs on Rockauto that were a perfect match! So I tossed some thread tape on the lil bastards and got to work.

I mounted the can to the core support. The mounting bracket wants you to screw in from underneath, going to the side of something. I imagine to have a "floating" look to it. I found that if I were to do that, the can would be sitting to low and cause the lines to bend too much at that angle. So I bent the bracket flat and mounted it that way...




Once I got the can sitting right, I started routing the hoses and trimming just the right amount to fit the bends right...






I'll probably find some kind of line management system (aka zip ties) to try and group the 3 lines together in a more cleaner fashion. Right now, they kinda look like an octopus or squid is trapped under the hood...




The next step is to actually pull the intake manifold for another cleaning of the valves. And then retest a year from then to see if the can helped.

Anyway... project complete!

Keep an eye on the Mishimoto catch can, ended up having mine get clogged.

[430hps4]

From the micron filter part?

What do you think caused it?

[Hippiekiller]

I believe so, haven't taken it apart yet. But that's my guess. Honestly, not sure. It didn't get much oil in it, but had some. I emptied it and went on a trip out to L.A., started burning oil like crazy. It clogged up and wasn't letting air go to the Oil Separator. Not much air was coming out the outlet when I tried blowing through it and that's what was causing all my problems.

[430hps4]

Let me know how it looks when you dig in there. I'm guessing that if it is indeed clogged, unscrewing the filter and shooting some brake cleaner in there will do the trick. But if not, I have no hesitation in just chucking the damn thing in the garbage and doing something different.

[430hps4]

So it's been a couple weeks, and I decided to open up the can and see what all I had accumulated. Keep in my, the Touareg is not my daily driver, so I've put MAYBE 1000 miles on?

The can was about 1/3 full, and it was mostly oil. No sludgy milkshake like you sometimes see in other posts.

I would have taken a photo, but clumsy me spilled the damn thing all over the floor!

[430hps4]

So another couple weeks, a lil over a month really. Maybe 2k miles? Here's what I am catching...




So it's definitely evolved from just being oil to the more traditional milkshake like color. It was also quite "sludgy" at the bottom of the can. Kind of like a really runny pudding like consistency, that you can see coagulating at the bottom of that cup.

Now, I don't know if its because the can was more full this time? Maybe excess air agitation?? Or maybe the fact that its colder out??? I don't know.


Either way... its that much LESS crap making its way into the OEM PCV system and intake tract.

Can this 4.2L application be massaged to work on the 3.2L A5?

[430hps4]

I don't see why not. Give it a shot!

[jschrauwen]

I don't see why not. Give it a shot!

I prefer not to try a "hit and miss and hope it works" approach.
I was hoping there would be someone who would know the similarities/differences between both engines wherein slight massaging could make it feasible to apply to the 3.2L.

You are over thinking the process. If you copy the steps that I took by collecting your parts... catch can, hoses, clamps, etc and utilize your OEM Norma fittings that connect to your valve covers, you are done.

You can do this on ANY motor with all PCV setups. You just have to understand the point of the system is to still allow excess pressures to escape. In doing so, you are reducing the oil/moisture vapors from making their way back into the intake track. It's just far more apparent of the FSI motors that this process is important.

If you are getting stuck, or are unsure of where to start... post some pictures of your engine bay. Make sure you get a wide shot, some closer shots of where your current PCV system is, and the connections to the valve covers. I'll help you set your system up.

You're right in me over-thinking this. And I'm quite comfortable to do the work myself if I just had the knowledge beforehand of what parts I would need to acquire.
I'll take some pics and post them up. Thank You!!

My original post of the Touareg forum lays it all out pretty good, step by step. Just gotta free up your OEM Norma fittings, choose your hose/line type, find a mounting spot for your can, cut lines to fit, clamp everything down.
