DIY: Cheap oil vapor catch "can"

There is no way Oil is getting tru. The Oil drops to the bottom of the Chamber, where there is a drain plug.

Just make sure that this filter is not to dense. You could build up to much pressure in the crankcase and maybe blow a seal. Just a thought.

System is made for an air compressor. and the Filter has a ratting, (5um) it looks like you can get diff. filters for more or less air. I was also able to blow air into the input and felt it on the output. so it's not that restrictive.

This could blow the whole catch can industry wide open!

I'm not big on trying to re-invent the wheel, but props to you if it serves it's purpose.

Not trying to re-invent anything. Improvising in the name of saving money

Found some right angle fittings. Didn't even think to look in the sink/faucet section! I'd much rather the fittings be metal but they're holding up to the heat so far. Curious how long they'll hold up...hopefully until I stop being lazy and find a place that sells metal right angle fittings.

Also put some Ts in place to have the "clean" side run into the filter inlet as well. The outlet is also T'd to the existing port that was installed in the silicone elbow of the ADM intake.

can you make a list of the items you bought and the sizes for nuts etc?

... pretty cool idea

you could always just let the outlet hang out in the engine bay, cap off the PCV inlet, and remove ALL oil from entering the intake.

had this on my 2003 SRT4. I got a real one this time.. why? Just didn't want to put a air compressor filter on my 35K+ car... with mods.. more like 50+

I thought about that after throwing away all of the packaging lol!

What's not real about this? The fact that it isn't a metal container? That metal can you bought does the same thing and might do it better but it also looks better. This filter is mostly hidden under the engine cover and I'm perfectly fine spending around $25 versus $100+. This isn't a life saving device where the quality (internally and externally) is extremely important. It separates oil vapor before making it to the intake.

You want function and good looks. I'm happy with it being hidden and functional. Price of the vehicle doesn't change that for me. Different strokes for different folks

That is what we started with back 12-14 years ago as we were running into detonation on the FI builds. We saw them catch oil right away so figured they worked, but still had the detonation. Then took the tb off and saw the IM full of oil again, added a second one in series and it caught oil as well.....it took a while to realize it is designed for such tiny amounts any car PCV system was over powering them...even with 3 inline, oil still pulled right through but they DID reduce the amount being ingested, so it is better than nothing.

Try what we did to see for yourself. No flaming, at least your on the right track!

Lowe's Speed Shop Kobalt catch cans.
We love 'em!

Here's the results caught in the RED can after the initial 1708 miles on the 2014 1LT Camaro. Yick!
