I found a great deal on a billet aluminum catch can I think will fit our cars and only costs $31.01 (USD) delivered.
Here are the pictures of the item I received:
74698


74699

It is a well made piece and I know car parts. The 300 SRT on the magazine cover was my last show car build.
I have no affiliation with the manufacturer, I just like to save money and want to share what I find with the forum.
Yes, it comes from China and takes a month to get here.
Once I verify it fits you might save more than a few bucks by searching Ebay for a BMW 335 Catch can.

I can now confirm that this catch can works with our cars. It uses the exact same diameter hoses as stock.
I'll post pictures of my install in a bit.

Just search ebay for BMW 335i catch can. Its available in black and silver.
You do not need the kit with the hoses, just the catch can.
Do not buy the one with a breather vent either as it will throw a code.
To install you will need about 2 feet of 5/8th automotive hose and 4 worm clamps.

Hello TX_Bandit,
Would appreciate seeing photos of the installed catch can. Anyone know if installing this item could somehow void the car's warranty?
I'll try and post a picture. Been holding off as I'm waiting for some fancy braided hoses to arrive but I guess I can post one as-is.
As for the warranty, I used to be part of the DFW Chrysler LX club and EVERY car in the club ran an aftermarket catch can and no one ever got any flack from a dealer. Even if they did complain, reroute one hose and in 60 seconds you are back to stock.

As I have the V4 intake I used the old factory air box attachment point.

I installed this a few months ago. Got the hoses from Auto Zone and the reducer Dorman- Help 5/8in X 3/4in Plastic Heater Hose Connector
Had to get a piece of aluminum to create the mount and had to modify it after installing the Abarth strut brace. I painted it black.
Must be different models for sale as the catch can I purchased fit the original hoses with no problem. If it doesn't conflict with forum rules I'm happy to share the link of the eBay vendor.

Here is the listing for the catch can I purchased. The hoses are a direct fit and do not require reducers or adapters
Ebay Catch Can

And here is what mine looks like now that I have added a braided hose cover kit

@TX_Bandit the catch can arrived. I thought I ordered black but it arrived unfinished, which is actually OK as it looks pretty nice. Is the hose size 5/8" or 3/4"?
Its 5/8th. And just a hint, auto parts stores usually carry heater hoses. Its a little harder to find, but try to get PCV (Positive Crankcase Ventilation) hose. Its also sold as fuel line hose. Heater hose will work but its thicker and heavier than it needs to be. PCV hose is thinner and easier to route without kinking and has a nice glossy finish. Again, either will work.

Just got the same catch can..quality item for 30£. Seems to work fine.
I used 19mm (3/4) hose which fits fine with a clamp. The barbs on the can are 20mm according to my calipers. That was the oem hose ID so not sure the need for 5/8ths unless I have missed something?
If it fits - it fits! Not a component that needs exact tolerances

The outlet is the side with the baffle
75819


You can increase the efficiency of this catch can considerably by stuffing one of these into the can
75820


These are stainless steel scouring pads. You can get them on Amazon.
The idea is you give the oil vapor something to cling to as it passes through the catch can.

The EC thread indicates the INLET for the can is the side with diffuser. Which is how I set mine up.
It actually doesn't matter but can affect efficiency. Itll still work..
BUT the baffle is only secured by hex bolts, so you can swap it round anyway within thr can to suit :)
Based on what I could find, the majority of catch can documentation has the baffle as the exit. PO-tato PA-tato. I agree that it probably doesn't matter.
But I will reiterate that adding the mesh to this model catch can results in a huge improvement in its ability to 'catch' oil.

Is this the most helpful on intercooler pipe leak? My mechanic advised me to change out the gasket instead.
Sorry, but the catch can has nothing to do with leaks in the intercooler piping. It simply removes excess oil vapor from the air circulated by the positive crankcase ventilation system.

@TX_Bandit have you gotten on the AOS delete deal yet? As soon as I get my car back... eventually? I'm going to do the AOS delete and catch can install.
The AOS on the 124 tends to fill itself up way faster than the 500s do, not real clear on why though. Here is a few pics of a friend's setup on his 500, shoot holes in it:
So far he has zero consumption and no CEL/MIL, car runs smoother and it turns out this should have happened years ago.
Wasn't aware of this mod. I found this article on the Fiat 500 Forum. If you read all the way to the end, you'll see the majority of the members don't think much of the idea.
It may work but I'll take a pass on this mod.

Is this the article you refering to:

That is all I found searching for AOS delete.
If it is posted on Facebook, that's a hard pass for me. With my software security background, Mark Zuckerberg is the frikkin anti-christ as far as I'm concerned.

Thanks. I'll take a look at it.

EDIT: Guess not, another FB group.

Just something to ponder considering the oil consumption issues the 124s are well known to have ...really quite annoying. My 500 Abarth didn't have consumption issues, well not after a catch can it didn't. The first 2k miles it freaking caked my fmic hoses with oil 😑

Anyhow, I'm going to do my 124 since it's only got 600mi and already has oil in the intake everywhere....
Please post pics and/or a how to if you do it.
