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.

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.

Hi, I have a 2013 International 4300 with maxxforce engine. I recently had the turbos replaced because I was told my turbos were bad. So I got them replaced but I still see that engine oil coming out of the crankcase breather along with smoke. And also where you check the engine oil level, there’s smoke coming out. You can see that when the dip stick is removed. Is that a reason why engine is loosing oil like everyday?

[@highwayta3696]

Would this create a problem with high oil pressure? Pressure over 100 even after changing relief valve on filter housing and not a single error code

[@MichealJACKSON-ly6cd]

I've been a diesel tech for 32 years. That sludge is supposed to be their. That's what a centerfuge does. It separates carbon particulates. People talk about things they don't understand all the time Ask the dealer what the interval is. Don't take advise from someone who can barely speak english. . DDs went to 45k PER DERTOIT almost 15 years ago and the centerfuge is one of many reasons not 30 or less. Remove parts if you like bit don't explain things you don't understand.

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.

[@LetstalkDIESEL]

The plastic part inside the oil separator/ Crankcase breather cannot be clean, since soot accumulates around it and you can notice how gets into really tight places. You should replace the whole oil separator. Volvo offers a kit to replace just the top part of the oil separator/Crankcase breather (this apply for Volvo engines only). For International, it depends, if that one has Cummins Engine does NOT use Crankcase breather as you should know. Maxxforce and A26 engines use Crankcase breather but Maxxforce is a pain to replace it, so you should use a new part instead of cleaning the old one, A26 seems to be a bit friendly but still same opinion like Maxxforce. Glad that you like my video and I hope this help you and never is too late to learn new tricks.

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?

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

[@LetstalkDIESEL]

If your crankcase oil separator still making noise after your turn off the engine, you can listen it, if you hear like a grinding noise when spinning, replace it. If no sound is found ayer turning off the engine, then your crankcase oil separator is fine (unless leaking oil). I hope this information help you and that for support the channel.

[@georgegonzalez8818]

Yes, it sounds loud as if bearing are grinding. Sounds like it's whistling or air leak?.

[@LetstalkDIESEL]

Yeah, it does sound like an air leak. So you should replace the crankcase oil separator.

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.

[@LetstalkDIESEL]

It is NOT normal that smoke come out from the breather, if you can see white smoke, there is the possibility that there is coolant intrusion into the oil pan. First check your oil color, usually water makes it milky, if everything is ok with your engine oil, then go underneath your truck and pay attention around the outlet of the breather, if you can see drops of water coming out then it means something is going on with your engine. I cannot tell you that is your problem exactly but you should take your vehicle the nearest repair shop for a look. I hope this help you and May God Bless You. Thanks for the support and watching the channel.

[@LetstalkDIESEL]

You could replace just the top part of the breather, Volvo dealer sells the kit for that. Also, you could replace the whole assembly as well, but it will be more expensive, if you are planning to use an aftermarket part, be sure it is from a recommended place and has good reviews before buying it.

Primero si tienes perdida de coolant o aceite, podrías investigar la razón de ello, usualmente cuando hay exceso de humo blanco de el escape, podría ser los inyectores, el empaque de la cabeza está dañado o algún cilindro está reventado, por mencionar algunas causas.

[@dougbesplug8851]

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?

[@LetstalkDIESEL]

1st. Wash your truck underneath, clean all the places with oil, try to clean it the best you can. 2nd. Run the engine for at least an hour, then go under your truck and pay attention around the engine area, perhaps you would be able to spot the leak. If you find the leak like this, try to see if you can fix yourself or requires a Technician. 3rd. If you cannot see any leak with the engine just seating and idling, then drive test your vehicle for few minutes in the highway, that way you will put more stress into the gaskets or the Crankcase breather. The leak might appear with this method. 4th. If after all these steps your truck still not showing a major oil leak, then perhaps your truck has another issue, that is not related it with an oil leak. I hope these steps help you to find out your problem. Thanks for watching.

[@dougbesplug8851]

Thanks I never could figure it out just add oil

[@youngdroid10]

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?

[@LetstalkDIESEL]

You might want to take a closer look to your breather and make sure that is the reason for the oil leak, but if you say there is oil in the other side of the engine, it might be something else as well. Try to clean your engine properly and check it out again. Alternatively, you could let a technician or mechanic take a look to pinpoint the problem faster. Thanks for watching.

[@flyingjstation]

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..

[@LetstalkDIESEL]

If you replaced the breather and the speed sensor on the top of the breather, it might the engine harness your problem, it is possible to fix the harness (if the damage wire is not to close to the MCM junction or inside the hard cover around the oil pan). If you had repaired the engine harness before this problem, the only option is to change the engine harness. This is just my personal opinion, for a proper diagnostic take your vehicle to repair shop to know your exact issue, ok? Thanks for watching and for the support to the channel.

[@flyingjstation]

Yea. Mechanic found out that there was a problem with the wiring somewhere around the engine so he bypassed the wire through another way i guess. Now the code is gone and looks good.

[@jasonpeterson2543]

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

[@LetstalkDIESEL]

What do you mean with “Illuminate”? Usually, you can removed the top part of the crankcase breather but you must remove it from the engine block... it will not leak oil from there because the oil level must be below of the breather position in the block. If you notice any oil leak that will be from the breather itself. Just put a small oil pan underneath. I hope this help with your question and thanks for watching.

[@harapalb2130]

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

[@LetstalkDIESEL]

There is no schedule interval to change your oil separator/crankcase breather. The rule of thumb is to change when it is leaking oil from the gasket or from the outlet side of the breather. Also, when a strong noise (like humming or grinding) comes from it. Those are the three things that usually requires to replace it. I hope this help with your question. Thanks for watching.

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.

[@LetstalkDIESEL]

The bottom part of the breather is aluminum, so just hit it a bit, or use a flathead screwdriver to separate the plastic top part and it should come off easy, like you said gently because, usually, it is not that tight. Sometimes, that happens that even after you remove the 3 screws still stick to the bottom part. So, just make sure when you install everything back, use everything that comes inside the kit. I hope this help and thanks for staying around.

I recommend you to change the Crankcase breather Sensor if the STOP light is coming on and off and Crankcase breather/Oil separator if it is leaking oil.

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

[@LetstalkDIESEL]

Can you rewrite your question? Charge Air Cooler and Crankcase Breather are two different parts and are NOT relate to each other.

[@1HSYURIDIA]

There s a open type crankcase for some trucks like maxforce dt. They made them close type wich what happen. the CAC get oily and plugg due to oil from crankcase. But the new stlyle open crancase its made to send oil or blow by to the atmosphere not tilo the CAC anymore. do you know or has any picture of that new open crankcase. Its call open type..

[@LetstalkDIESEL]

Ok, now I understand your question. Those in that kind of engine (Maxxforce 13 older design), you have to replace the whole assembly, I did one of those once, hard to remove it from that engine, so if you want to replace just remove to whole assembly, I do not have photos for it, but if that it is hard to remove just replace it, remember if it leaks again because you just replace one part and put it back it will cost you more money in the long run. In the newest 2019 A26 engine and others, they removed that and it is like you said... just going out to the atmosphere.

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???

[@LetstalkDIESEL]

Check the engine oil level is fill properly. Perhaps both Crankcase breather are bad. You should get a new one to eliminate that possibility. Also, check the surface area where the Crankcase breather gasket sits maybe it is damage. Try to apply a thing layer of silicone around the gasket, this might help to prevent future leaks. I hope this help you with your issue and thanks for watching.

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..

[@LetstalkDIESEL]

You might be able to do that and may work temporary but the problem is inside the spinning plastic cylinder and the bearing, since it gets clog with soot that slows down the cylinder, even if you clean it and may cause the breather to fail. So the best thing you can do is to replace the whole crankcase breather so you will not run into problems later, like a oil pan gasket leak since the pressure cannot be release properly because a clog breather. Freightliner does NOT sell the kit to rebuild the crankcase.

@@LetstalkDIESEL yeah, I just took mine off and took it apart. It's not serviceable. You can separate the top plastic part, and the down pipe, but that's about it. You can't actually take the spinning piece out of the plastic housing. But mine spins very freely. It still leaks a whole lot of oil. That and the oil pan gasket, and also the camshaft housing leaking. I'll just replace it, and take it to the shop to have the oil pan and camshaft housing gaskets replaced. Thanks for the reply tho. New sub. Keep the videos coming. Very helpful! 🍻

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

[@LetstalkDIESEL]

It is part of the job, because when I really want to know something relate it to the engine or other parts, touching textures or fluids might help me to understand better what is going on. Of course, in regular basis I use gloves. Thanks for watching.
