A Weird Upgrade Every Sprinter Owner Needs 

Another solution which would be 100 times better. Is a sealed system catch can. Where you can capture the oil and drain it out at regular intervals, and you wouldn't get the smell, or oil spraying off that filter when it gets soaked. Catch can kit is about $50 for a Chinese brand, they work as intended.

The PCV delete/bypass (using a simple breather port like that) will fail an emissions test if you're in a region where that's relevant and the tester notices the modification, but otherwise this will work fine. So obviously for off-road or otherwise not road legal vehicles this would be a no brainer. An actual design solution that would avoid this and maintain PCV function would've been to connect the crankcase breather downstream of the turbo's compressor outlet, so between the turbo and the intake manifold. You'd reduce turbo efficiency just slightly and likely increase crankcase pressure somewhat as well (due to turbo-compressed air pushing back against the flow through the PCV tube), but that should be such a minor issue as to be ignored in most cases, especially compared to what they actually did. The only case you couldn't use that solution would be in a gasoline engine using a carburetor or single point fuel injection upstream of the turbo (or supercharger) in a draw-through configuration as you'd have fuel vapor + droplets in the compressed charge in that case which would thus contaminate the crankcase and oil. (but that's a nonexistent problem for modern commercial engines ... I suppose water injection upstream of the compressor intake would create a similar problem, with water vapor/droplets being pushed back into the crankcase, but also not a common feature)

😮 same setup on citroen dispatch 2.0hdi the rubber pcv valve is usless changed 3 in a year going to give it a try thanks

But , of course , a Catch Can is superior , and still EPA compliant . Those Fumes going directly to atmosphere is Illegal . I don't disagree with what you're saying , but Legislators have made it more difficult . Like EGR systems that are ENGINEERED to create Engine problems .

After a week of breathing that in you will look for another solution in form of Mann Provent oil catch can. I did this exact mod before the catch can on my om642 ML and you could see fumes coming out of the hood and grill. Not to mention that “blow by” was calculated in to the ecu with mass airflow sensor and adequate amount of extra fuel was ordered.

You must wash the tiny filter inside the crankcase breather first that will release the pressure inside the engine there in no point fitting and after market filter as the original is blocked there is to much oil going to the new aftermarket breather it a breather not an oil separator you will have a mess of oil everywhere and smell off burned oil in the cab in time I like your idea off blocking the fume pipe I have done that to with great success

Awesome. 🎉thanks for doing the video. Nice of you to pass this gem along to the sprinter community.

I'm goingnto try this on my 2010 ML350. That thing is burning through oil aomething crazy. Had Mercedes do an oil consumption test and they said its normal.

This may be a dumb question but why no mention of the engine's oil separator in this scenario> Doesn't it play a part in all this?

The link to this part said no longer available! Is there somewhere else I can get one?

2011 Sprinter every year a new oil leak or 2. Even under Warranty. From diff, manifold, oil sump, pressure sensor, shock absorbers. You think it’s fixed and another comes. It’s never not had a leak fixed without causing another one every time. 😢

DON´T do it, your PCV not only bring Oil through the PCV, also fumes that smells like exhaust fumes when you let the PCV goes directly to the filter, it always get the fumes in the engine bay, and also inside of the vehicle and you will breath it in... BETTER: install a catch can, it separates the oil, and bring the fumes back to the intake

Hi, just seen you video and Im wondering if it will be the same case on Mercedes Viano/ Vito 2013, 2.2CDI ? Is it the same set up?

Are there specific directions to installing this breather? Total noob at this and want to get my head around how to do it right.

2019 Mercedes sprinter 2500 v6 turbo diesel. I occasionally notice a small blotch of oil on the garage floor. I do not believe it is a general oil leak, I feel that I notice this after we have used the van to tow a trailer and side by side. You mentioned this may occur when the turbo is put under load. Would it be possible that what you are describing would throw a small, individual splatter of oil on the cement floor, the engine bay seems clean and free of oil, is this bad for the engine? I have brought it to the dealership to "fix it once, maybe twice now" they have put a new clip on it under warranty. But i don't believe the dealership is worth a hoot. I wonder if I should try your method.

just found your channel 😊! Ive a 2004 t1n 2.2 l . i have this issue on mine its leaking and oiling everything 🙄 , why does this happen in the first place , is something worn or broken ?

How do you do it in the picture of the old sprinter?

this breather upgrade kit is not showing available through Amazon. Any other options?

1960s called and they want their mod back. 🤣

I have a sprinter 2012 with 2143cc OM651 Do you recommand to instal this kit preventive ? Thanks for your videos!

Will this work on a 2004 sprinter??

It says no longer available:(

Hi, I am new to your work, I had a 2007 LWB Sprinter , In 2019 was travelling up a steep hill behind a long queue of lorries And they were all slowly slowing down so I decided to overtake drop-down gear into fourth exhilarated also there’s a big gosh oil blew out of my dipstick holder and the engine went into limp mode, I had the vehicle recovered and I was told I needed a new engine so for the time being I just drive around very slowly ended up ditching the van never found out exactly what was wrong with it do you have any idea what was wrong. Phil

Thank you. I did not see the link did I miss it?

I am getting limp mode P0299 and have oil in the turbo hose..etc Would like to get the fix (Crankcase Breather for PVC) but it isn't on Amazon anymore. I have a 2004 Sprinter 2500 2.7L. Any help with either how to get the Breather for PVC or PVC part would be greatly appreciated!

Hi you are dead right , what size is the filter connection and or hose will go purchase on and a reticulation block off fitting

it's not available on amazon anymore. what company makes this?

If you sevice the engine correctly this would not happen. There is a breather filter shich should bd cleaned or replaced. Just as cheap.

In the hose i have a sensor its called the elephant hose , what are you suppose to do with that?

What’s the part to replace the valve

I think the main reason you are not going to see too many mechanics recommending this is because blow by gases get re-burned for a reason, they are horrible for the environment. You're basically just pumping oil vapor and raw fuel into the air. The customer is going to smell it, and defeating emissions equipment is a crime so its definitely a risk for a business to do this.

Bro sprinters supposed to have oil passing thru the turbo and intercooler, wtf u talking about

What is the cap with the rubber valve called?

Your way seem fine but illegal in a lot of places, I have installed a proven 200 catch can and capture the fumes & oil!

what is the name of the plug that is failing to create this issue. I'm seeing lots of oil in my coolant system now. Looked for the products and the amazon listing is gone.

Smog legal?

Does this apply to 2008 2500dodge sprinter van?

Kit says no longer available???

ive a 2005 2.7L sprinter and im getting crazy amounts of black smoke when under load/ setting off. engine is very tapety as well. i take it i may have injector issues as well as this?

😊 engine does run cleaner by the turbo does not spool as efficiently that back pressure that's building up in the cylinder head and actually helps spool the turbo

No, this would not work. The engine bay will be covered with film of oil in no time. Catch can could be the next solution.

Use a catch can bruh

This is just lazy, replace it with the proper parts, it will create more issues, it's not that simple.

catch can!

I have a OM642 2013 3500 now with over 300K Will that work for mine?
