Look At What Came Out Of My Catch Can

[Silverado4x4]

I don't think it would be a bad thing either on the Mercedes but dumping what's in a catch can back into the motor due to catch cans sweat and have condensation making water a big no no.

Verify your application, J&L Catch Can

While there are others out there, many cheaper, this is a stupid easy plug and play installation. No cutting, maybe a few 10 MM sockets, propery snap connections, hoses are the proper them and it seems to work well and is good quality. Maybe a 15 minute installation if you have the tools at hand and a step stool.

Wait... don't install a catch can. I heard thats the only way oil is getting up there on some of these DFM engines

Can someone please give me a make and model number of one of these catch cans.. thank you

Are you asking about one of the stock ones from an early 80's Mercedes? You did quote a message that was talking about an early 80's Mercedes oil separator that returned the oil to the crankcase.

That'd be WAY more time, effort and money to install one of those vice just buying one of the MANY commercially available catch cans meant for a new Tahoe, but if you really want to go down that silly rabbit hole, then look up any Mercedes with a OM 617 (like a 81-85 300TD for example). All of them will have a factory oil separator built into the center of the air cleaner assembly (see pic below). Personally, I'd just buy one of the several that are out there meant/ marketed for the Tahoe before trying to adapt something that's 40 years old, but have fun I suppose.

If you were actually asking about an oil catch can meant for a new Tahoe (which is what I hope you were asking about), then see link below

For those who think it's easier to annoy you than to Google '2024 tahoe oil catch can' themselves.

The chemical difference between crankcase motor oil and what's in the catch can
is the reason why catch cans exist.
Otherwise, why not just pour what's in the catch can back into the crankcase?

DON'T DO THAT.

Why would you want to return that off-white stuff in this pic to the crankcase?

Don't forget to click on the pic to get a good look at the mung under the 'soy sauce'.

I can't see a reason why it would necessarily be a bad thing to return the oil to the crankcase
(assuming all the lines were cleaned / flushed after assembly of course).

I don't think it would be a bad thing either on the Mercedes, but -
dumping what's in a catch can back into the motor due to catch can's sweat / condensation making water?
A big no no.

There's a reason why Mercedes stopped doing it - probably heat cycling.

Makes me wonder where the catch can actually belongs,
but definitely convinces me that catch cans should be de rigeur.

Google JL Oil Seperator....Once one the site you can find for your model. It takes about 15 mins to install, very easy install. The connections with the JL are just the same as the factory ones.

Mercedes still has them, they are called Oil vapor sepearators, and on my 20' S class, they sit behind ALOT of crap that has to be removed to access....
THe Benz ones has little half circles inside to keep the oil flowing in a downward direction. They do drain back into the case. I changed mine out when I did some major work recently and it was probably a waste of time as there was nothing in there. That is a twin turbo 583HP motor and it was dry, which is not bad....

I went to J&L's website, and they don't even list Cadillac, so I'm thinking that I'm missing some information. If y'all would educate me, I'd appreciate it. I have an '07 Escalade with the 6.2 liter L92. Thanks.

Assume the application would be the same as the 2007 6.2l GMC Yukon. But you may want to contact them and check for sure.

Thanks. I tried that in their search, and only got shown a 6L option for '07 and '08 Yukon. The '09 shows a 6.2, but I still don't know what is, or isn't, the same between the two trucks.

So here I am.
