Ah, yes, I did mean steel scrubby! I have a bunch under the sink.

So it turns out that most of the amazon catch cans have in/out ports that are M16x1.5.
Finding nozzles with barb fittings with IDs >12mm shouldn't be too difficult.

Might have to step up or down a few times getting hoses to match, but this all feels eminently achievable.

I picked up a provent 200 knockoff on amazon.
It's definitely overkill, but I paid about $15 as a warehouse deal.

I'm thinking of mounting it directly to the air filter assembly, in the triangle region between the assembly, the valve cover and the A/C line. The thing I'm concerned about is the heat coming off of the exhaust manifold.
The provent is some sort of plastic.



There's no turbo below so I imagine it's considerably less heat than say a 617a. Any ideas what temperatures I might expect in that area under full load? Need I be concerned?

Another thing. The provent has 1" ID inlet/outlet nipples. I need to find a way to step down to something like 1/2" to match the stock breather pipe going into both the valve cover and the manifold. I assume I should be using brass barb reducers, but that's based on my assumption that the blowby gasses are hot and oil might erode plastic. On that note... should I be using fuel hose for this application or is oil heater hose or other, okay?

What year model is your 240D ? .

My '82 has a oil mist separator I I don't see on your underhood picture .

Maybe that's why you're needing a catch can but I doubt it .

Early morning Nate?
The one in my signature -1981

And that is exactly why I need one.
They only shipped on 82 and 83 models. Hence the retro-fit part of the post title.

Yeah I didn’t quite get that a few posts back. My 82 240d had the separator bolted to some bosses on the intake. It also had a drain to the sump.

Mine got cracked and leaked. The bosses were a convenient mount point for other accessories.

All done.











In the end, it was a pretty light unit and didn't require too much in the way of mounting.
I took the opportunity to degrease my intake manifold, replace the original gasket (shredded) and replace the breather elbow.




Guess we'll see how it goes over the next few months, but I suspect it will be doing its job. Will keep this thread updated with observations.

Nice work Shern. Very clean looking installation.

That reducer is an useful looking part. Where do you get those?

Thank you kindly.

Those reducers are actually dishwasher connectors I bought at homedepot.

I bought 1/2" ID fuel hose that fit just about snugly into the 1" ID inlet/outlet ports on the canister. I was able to twist the fuel hose into the narrow end of the connector and then about a 1/2" past the wide end and then into the plastic port of the canister.
Not sure what kind of rubber the dishwasher connectors are made from, but the the way I'm using them, they're likely not seeing any vapor at all.

On the valve cover/manifold end, I found an extra breather pipe at the JY and hacksawed 2" inch sections to use as joiners. Shoved them in there pretty good, they're mostly invisible.

Well done Shern ! .

I guessing you'll drain the clear plastic hose every oil change ? .

Exactly. Routed the drain valve near the sump plug for that very reason

I hope they'll last but Diesel contaminated oil tears or anything rubber quickly .
