So after continuing to find loads of oil in my IC and throttle body everytime I pulled the car apart I finally bit the bullet and put a catch can on.

I bought my unit from Autobarn for about $70. It is stainless. Nothing too fancy. There are cheaper and better ones on ebay but I had the car apart and didn't want to wait.
First step was to find a spot for it. There's no space in the B4 engine bay! I finally managed to squeeze it in next to the IC and master cylinder behind secondary turbo and above the secondary dump pipe. There is less than a cm of clearance either side. This spot was perfect though as it is close to the crank case breather.

I managed to rework the mounting bracket to make use of the bolt along the top of the firewall (see picture). It is positioned on an angle so that it wouldn't knock on the IC or master cylinder.

Next step is working out how to run the lines. I elected to run a single line from the crankcase to the catch can. From the catch can I tee out to the PCV and intake pipe. Subsequent to my install I was told that it is just as effective to tee from the crankcase to the PCV and catch can, then from the catch can to the intake pipe. Check out the attached diagram for an example of the alternative (Thanks Jimbo).

The pipes run down from the catch can to the crankcase and tees under the intercooler off to the PCV and intake pipe. Because the hoses run so close to the secondary dump I decided to make a heat shield. I used a long bolt down from the IC mount to hold it in place.

The hoses are clear so I could see what oil was getting through. The catch can didn't come with any material or filter to block the oil getting past. I used steel wool as that's what I had. Seems to block most of it but I can see some starting to get through after prolonged use. Thinking I might try other materials.

So far it appears to be working. I haven't removed the intercooler since but it has already caught a decent amount of crap.
Also pictured is the little fuel filters I put between my BBoD and any source of possible contamination. This was an idea of my own and they were blocking oil getting into the BBoD before I put the catch can on and there hasn't been any side affects.
