That is the question. I saw one being used in a car and after around 500 miles, some gunk had already collected inside the can. Is it worth installing or does that bit of oil not matter all that much in the long run?

Never used one. One of my mopars had 250,000+ miles on it. A buddy's got one with over half a mill now. No catch can in it, either. Some guys swear by them.

Results vary between engine to engine. But it never hurts to have one to reduce the blowby that'll go back into the intake manifold and "potentially" foul some stuff up

I've got one I put on mine. First one I've ever had. I'd rather dump the trash than have it go back into my engine... Caught some trash in it already after 10k miles so I'd say it's worth it.

Do you have any pictures of it ?? Which brand ? Sorry I'm so inquisitive lol

Feel like catch cans aren't really a necessity unless the engine is a direct injection turbocharged engine, this includes EcoBoost too.

my durango catch can gets maybe a tablespoon of oil in it every few months.

As long as you can afford it, really no downside. Is it absolutely required on N/A motor? No. But it definitely only helps. Plan on installing one on mine soon.

Perfect explanation ^^ And you can find ones that vary in price range, from a basic universal to something cool with filters sticking out lol

Great link indeed and the great thing about being on forums like this is when trying to get even wilder with creating a catch can setup, often some knowledgeable people will give their input and help direct the development, or just tell you what they did:

If you want to go even wilder and have the skills to do so when making your catch can, you can fabricate multiple internal baffles as well. These are used for serious racing applications where oil in the can may slosh around due to high g-forces and cornering loads and speeds, and are designed to prevent any oil from escaping. In these high performance applications, it may also be beneficial to run a line directly back to the oil pan in place of where a drain bolt may be.

Personally I was using one on my 13 Sport with the Hemi and every 4,000km, it was near full. I uninstalled it when I traded it in for the Rebel and installed in on the Rebel right from the get go. I'm gonna wait to get to 3,000km to see how much I filled it up hehe. Here are some pics of the can installed and when it was ready to be emptied on my 13.

That's actually quite a considerable amount in that time span.. Just for a better judgement, how much (mL) was in there ?

I know right, that's why I think it's totally worth it. Imagine if all of this would be recirculated in the engine.

The one that is more of a caramel color was during winter months so it includes condensation that turned into water so this is why it was even closer to being full.

In terms of quantity, i'll try to look it up but it's a considerable amount. Has to be close to 5oz or almost 150ml...

Well there you have it, 800km in and this what I've gotten so far... Not even one time was it at full throttle...
