Heavy Duty Diesel engine 101 Episode 1: how the Oil Crankcase Breather works. 

My brother called me this morning with same problem I sent him your video, thank you amigo.

You really make all this so simple to understand and learn.

I did not know what this did or was for. I just needed to change it.....this helps me understand why I had oil come out when replacing it.

Thank for the great video on how it works and how to service.

Thanks for your videos and quick reply, I replaced mine by myself again much thanks

Thankyou, your making a difference for this owner operator by sharing your knowledge. Not only with repair but with prevention knowledge as well. Thank you and God Bless.

Thank you for the video!

Thank you so much for this video. This is the only video on RU-vid that explains everything and the option to change just the upper part. Volvo is very reluctant to sell just the repair kit.. My breather is dripping oil.from it's exhaust pipe. Ofc if it is not spinning the oil is getting dumped outside through the exhaust pipe. I will.order the repair kit online it's around 230 vs 1600 from volvo.

Thanks for the advice!!!!!!

Thanks you explain it really good 👍🏼

Thank you for sharingand explaining it.

Thank you good job. 👍👍

Thanks for info here to stay sir.

You know that’s pretty cool, I kind of like to get myself prepped up a little bit so when I do have a problem I have a little bit of knowledge so I can fix it, I bought the kid They sell for that and I have that saved up just in case brakes on me I can take it I’ll clean it and put them back together, thank you friend, 👋👌👍

Thank you Alex appreciate it

Just bought my second rig after totaling my other inw I had after 7 years. Prior I had no experience on DD15 engines as I had an ISX. Very thankful for your videos.

Es todo hermano me encanta este video.

Decent video 👍👍👍🇨🇦🇨🇦🇨🇦

Muchas gracias Por la explicación, en mi caso el dd15 y esta leaking oil... Thanks again

Thank you sir

Hi ! Thanks for explaing this. Mechanic has had my car for a week..ordered and received the part 2 days ago. Now he says..3 more days to pick it up. Now i realize its not a big job. He just put me on the bottom of his list. I will change my mechanic after this. Im a 71 yr old woman..guess he thinks i wouldnt know how long it takes. You explained this very clearly. Thanks

I never would imagine that the blow off vapors could cause sludge. interesting. I cleaned mine last year and it was sludge free. It spins fast after I turn my truck off. At least I feel better about changing my oil often. I use full synthetic. Expensive, but, my truck runs like a champ. Thanks for this video.

Seen a lot of Mercedes/freighliner engines with oil leaking from the spinner breather, you can just the spinner kit now from Febi. Great video

Hi, thank you for your helpful information. Is it ok for a new one to have some leak?

Looks like the breather hose that comes out of the side of the CVV on my 2016 Volvo 670 has cracked in half. There was a little smoke coming from there and I think oil as well.

Can you show video of removing and cleaning then installation

Could this cause a higher oil pressure reading if it is faulty I do have oil seeping from the sides of the breather and exhaust port

On D13 I have Leakey gasket , which is between engine and separator connected .

Good sir nice explain please make more video regarding Freightliner cascadia

Good explanation ! How do you get rid of sludge ? Or is that the death sign for engines.

hi how did you opened?? i try to take out filter not comming out any help ? thanks

Hello Alex, I have Volvo D13 engine, want to work on oil separator, can you please give me instructions, I can do it myself

Hey man question. I just had mine replaced on d13 engine. But the new one now makes a noise for like 3 seconds after i shut the engine. Is that normal or its supposed to not sound at all?

Can i keep the hose or do i need to buy a new one also where can i get the gaskets from?

What did you said if the oil is being leaking we should check first?

Hi, if code came up for cranck case fault, we have no leaks, can we drive 3000 miles to get back home then fix it? Thank you

I have DD15. I change the crankcase breather but smoke come out from breather ? Is it normal. The truck have 715000 miles Any opinion

Hello master. I have dd15. From crankcase breather smoke come out ? Is it normal?

Buena esplicasion oy me tocó que canbiar el del camión

My mack Volvo dealer won't sell the kit do you have a part number

y haciendo un bypass del aceite que retorne al carter?

I have the same issue with my 2015 frirghtlinner DD15 and thinking about changing it myself but do I need to drain oil out or not?

Thanks bro nice explanation I have Volvo d13 808500 miles my crank case make noise abt 3 min aft stop engine little bit oil leaking from block n crank case so I have to replace whole part or only gasket please reply

Got very little fume/smoke coming from oil cap. 2015 Volvo d13, 390k miles. Breather never replaced. Any idea whether it's bad Breather or engine problem? Thanks

My truck turned off while I was running. No lights on dash came on at all,No gauges were low,Everything was perfect,I eas checking my gauges during the whole trip,Then I made a left on a stop sign and as soon as I straightened the truck to take that street my truck turned off. Then I tried to turn it back on a few minutes later and a lot of smoke came out from that part that you are showing us right now. The dash started showing low voltage and then my truck didnt want to start again. I checked the bateries and the said the batteries were good. A lot of smoke came out of that part,My truck is a freightliner century. What do you think would be the problem? Please help me with this. I really hope you can write back soon because I have 5 cars on my trailer that need to be delivered these following days. Thank you so much for your time and your videos. God bless you.

Hey bro, I have d13 engine 2014 freightliner cascadia. I had my truck sit for 4 months due to covid and then i took it out for a spin the other day and got this MIL light/check engine light on and when i checkeed the codes..it said spn5444 fmi1 . It reads that oil breather too low. So i changed the breather, speed sensor and check the wiring but the problem still exist. Please advise..

Is it possible that the motor can damage the crank case filter because I put one in april 2020 because it was leaking oil and a code came on so I replaced it and problem solved 7 months later while I was driving I heard a pop noise on the driver side I stop and noticed that I was spilling oil I thought that it was my crank case so I replaced turn on the truck it seems everything normal 15 or 20 min later I heard the same pop noise what could it be

I like your video I'm having problems with my International and I just bought that piece since I'm an old mechanic I like to take things off and fix them is there any way that you can clean this and put it back on.

I got the code for cvv but want to ask, if i have oil leaking on both side of truck and all the way back to fifth wheel part of frame, could this still be the issue?

Trying to find the crankcase filter speed sensor but it’s not on the filter itself. What other location is that thing at?

Hello Bro , I want to illuminate the crank case spinner . Could I remove the filter plates? Or would oil come out blow by ? Thanks

Hi what will hapen Continue to drive Bad oil separator

Hi my 2009 Volvo D16 is using a lot of oil, gallon a day and Volvo said maybe the separator stopped spinning or a valve in the separater unit is not working, my blow by tube is dry it’s expensive to replace, $2000 they recommend a lot of expensive repairs, what are your thoughts?

Hello boss can this cause my truck to shut off? Code is showing some kind of crankcase pressure sensor fault ..

Hi do you have to worry about oil dripping when you take the breather apart since it should sit at the top of the engine?

We need links to parts.

Hello sir. I got a code that says crankcase ventilation system disconnected, i don’t see anything wrong with hoses,but it seems like there is some rumbling noise coming from crankcase filter when the truck is on, when I turn it off, there is no noise, so I’m little bit confused. Do you think the crankcase filter is bad,or clogged or something else? 🤔 Thank you

What can happen if u drive like a week with a bad crankcase breather filter (leeks oil) ? Can blow up a cylinder or cause some other big damage on my cascadia?

Hey. Question.. my is leaking coolant!!🤯 any idea!?? Thanks.

When I turn off engine on my Volvo d13, this part makes loud spinning noise. It's that normal?

How do you change the crankcase filter on a Volvo D13

Hi Sir, great video!!. my question is on my volvo it is making a "whistling sound" do you think the crankcase breather is bad?. thank you

Do i have to reolace the crankcase breather or could it be cleaned?

My crank case separator only leak at square gasket , at engine valve, my separated or filter can be cleaned with diesel or brake cleaner , let me know please,

Alex when i remove the breather on the Volvo ( the 3 screws) does the whole top half of the unit come out together, i took one off today but the bottom half stayed on, do i gently tap on it to remove it, or is this a sign that this part is no good I'm needing to replace the seals on mine.Any reply would be great and thanks for all of the helpful videos.

Hola una pregunta un bad crankcase breather puede causar humo blanco? O smoke from the oil dipstick, tengo una international maxxforce7 😭 corre bien prende bien pero habienta execivo humo blanco cuando manejas y tambien m di cuenta q sale como vapor del oil dipstick si lo saco,? Sabes q podria ser? Ya replace el turbo, egr, y water pump, creo q el crankcase breather podria estar mal pero 😐 ya estoy perdiendo la fe y dinero con esta troka el humo blanco no para d salir, ojala y m puedas ayudar 🙏

I changed it but I still have the code Engine Crankcase Breather Oil Separator Speed SPN 5444 FMI 1 what I have to do?

Does a 1994 international school bus DT466 have a crank case breather?

Whats the new update one wich ls open type to avoid oil going to charge cooler??

Do I have to empty the oil off my engine before changing crankcases breather

Thanks for sharing My 2014 d13 had a Stop engine warning and the code.. SA 16 DTC P113500 which says online crankcase pressure too high you think replacing the breather should fix it or it's a crankcase or oil pressure sensors.? Thank you

You can clean old one I went to buy new $500 mechanic told me just clean it no need to buy new

puede trabajar eliminando ese respiradero y dejando el tubo por fuera ?

I do my PM every 16K.

I wonder if his oil pressure went up

Does the Detroit 60 series have it?

A mi Cascadia dd15 sele cambió el crankcase por otro nuevo por que estaba tirando el oil y quedó igual alguien más que le allá pasado lo mismo? Solo tira el oil cuando está andando no lo tira cuando está parado y encendido

My Freightliner dd15 it's leaking a Lot of oil from the Crank case i chance for another used one and same thing leaking a Lot of oil whats wrong???

900000 miles on my dd15 and just asked for it pm every 20k

Who knows how often should I change my crankcase breather(filter) ???

Hey Alex where are you located?

Took it off like older models i ratter have more oil pressure to my bearings than to this waste

estoy fuera de los Estados Unidos

It would have a problem for the engine

LOL You have to maintenance every 200,000 miles this one too LOL Nothing has to do the oil with that

Can you just remove this, take it apart and clean it? I have a dd15 engine. I don't see any broken parts. Seems like you could just clean it up a little..

Jesus! Why do you keep playing with that gunk? Bare fingers
