Catch can kits for Mk5 GTI?

[maltbbe]

What are the options for catch can kits (with PCV adaptor plates, hoses and mounts) for Australian Mk5 GTI owners? Almost all the kits on US websites mount onto our passenger side engine mount, but on Euro/Australian GTIs that space is filled with a carbon canister. I'm aware of the Forge kit (Oil Catch Tank System for 2.0 Litre FSi | FMMK5CTC | Forge Motorsport) and I think 42DD make a system that can be mounted in a few different places in the engine bay (Mk5 FSI Ultimate Oil Catch Can Solution - 42 Draft Designs), but the Forge kit is crazy expensive and I'd like something a bit more stealth than the 42DD. I'm keeping the factory engine cover, which I think might limit options for pipe routing.

If anyone's put together a catch can setup/mount from different kits, or fabricated their own, please feel free to share! Open to all options. I've been keen on the kit idea since I'll need to get an adaptor plate anyway, but if there's a cheaper and/or higher quality option I'd go for it.

Sounds like you need the 42DD Stealth catch can....too bad i just sold mine about 2 weeks ago.

See some photos below of the custom locations that i had mine mounted on my Golf R. Problem you will have with the standard engine cover and intake is the lack of room to mount the catch can as it is quite big.

I have the 42DD ultimate catch can installed where the carbon canister sits. I managed to relocate the carbon canister to where the front bumper crash bar sits. But i also have a K&N intake which makes the fitment work but limits areas where i can place a catch can.

This is neat! I wondered if that mounting point next to the battery would work. Are you using the hoses that came with the kit? And I'm guessing those are both custom-fabricated mounts?

I'm using one of APR's old Carbonio intakes, so that probably takes away even more space, but I'll go measure a few things now. That engine bay looks wild

@kdog how did you relocate the carbon canister? I've read a few threads on that but it sounds like a big job - the hoses running to it are welded plastic right?

[Lucas_R]

The bracket was nothing special - just a piece of flat bar mild steel i got from the hardware store that i bent to shape and drilled a few holes in etc to mount it. Then i painted it black to blend in.

If you have the old APR Carbonio intake then you should (from memory as i used to have that same intake about 5 years ago) be able to fit the catch can in the same/similar location as i did in my pics (using the vacant mounting post near the battery). I just used the rubber hoses that were provided when i purchased my catch can kit. They are nothing special - just 19mm ID rubber hose from Supercheap/Repco etc.

And as another member mentioned above, another option is to move the charcoal canister to down under the front bumper area and then mount the catch can where the charcoal canister used to be.

Great - thanks heaps for the advice. Looks like one of these kits is going on my shopping list. I like the idea of mounting it behind the passenger side headlight too, if clearance isn't too big an issue.

look on AliExpress for a forge "imitation"

[maltbbe]

Had a look, but they're only selling kits for TSI engines - probably not worth it if I have to get an adaptor plate anyway. I've seen a few people suggest this - is there a big difference in quality?

I'm not sure where the pipework goes on an EA113 but you should be able to cobble something together with all/some of these parts.

PCV delete (Afrika) plate? ~$25

Forge forgery $50

Full kit for an EA888 but maybe all the bits except for the plate are applicable? This kit includes the relocate for the washer bottle filler. $175

Thanks for this! I think those PCV delete plates don't have ports for a catch can, but otherwise this could work well. Hanging out for something used to turn up on the forums...

If it's like the TSI then the OEM has one hose to the inlet manifold and another to the pipe just before the turbo. The delete plate has a single hose that goes to the catch can and then to the inlet pipe before the turbo. The inlet manifold connection is blocked off with the supplied bung.

not really, hardest job is finding where to mount the bloodying thing.

they are but if you cut it very very carefully with a sharp razor or even get a hose thats wide enough to go over the top just do that.

i can provide photos if you want how ive done it.

@brad I think FSI engines work a bit differently - the outlet and inlet for the OEM PCV valve are next to one another, so catch can adaptor plates end up looking like this: Mk5/Mk6 2.0T FSI Catch Can Conversion Plate (1/2" NPT) - 42 Draft Designs. Seems like pretty average design to me (not that I really understand how it all works lol) but I'm gonna assume it was improved on TSI engines so that the PCV valves stopped failing all the time... The single outlet left on FSI PCV delete plates clips on to the OEM breather pipe.
@kdog photos would be rad if you can! PM me if you can't upload them here

For anyone curious to know how I solved this...

I ended up getting a catch can adaptor plate and boost cap from 034Motorsport (through urotuning.com), and had 1/4inch BSP fittings tapped into the inlet and outlet bungs. I bought a Mishimoto compact catch can off Gumtree, and used some 5/8ths heater hose and fittings from Pirtek to connect the two. The whole setup cost about $350, which is way less than it would've cost to import or locally buy a complete kit (most seem to go for about $650).



Inevitably, the problem was finding somewhere to mount the thing... my plan was to mount it to a hole on the engine cover (see second photo below), but the hose was too thick to flex without kinking. Right now, it's zip-tied to the carbon canister; it's secure, but it looks real sketchy. I think I'll eventually replace all this piping with AN fittings and braided hose, and mount the can to the bolt securing the top half of the washer bottle (underneath the plug connected to the coolant overflow tank).





If anyone's looking at doing something like this, VAGparts.com.au has at least one 034Motorsport FSI adaptor plate in stock. They sell two models of these plates, one with barbed bungs and one with AN fittings; I'd 100% recommend going for the one with AN fittings, since (for some reason) it's cheaper anyway and you can spend what you save on better-quality hose. The Mishimoto can is a good option just because it's so small, and it seems to be one of the cheaper name-brand options out there.
