7 yr old video sure came as a life saver for my 2003 BMW Z4. I appreciate the explanation and my confidence level sure went up on this fix.

[@larrysmith4296]

This check-valve mod really works! Thanks 50sKid!! Ordered the valve, received it 4 days later and our bad oil consumption problem was eliminated on our 2001 e46 330I. Quick note - you can do this mod in about 25 minutes if you do it this way: Remove cold air intake tube, filter box and top intake rubber hose. Then look down the dipstick tube (to very near the pan) and locate the oil return tube coming down from the crank case ventilation separator octopus. With a sharp 4" knife, reach way down and cut this hose about 1" above the top end of the barb from the dipstick (assure room as you need to press the check-valve barb into the hose without interference from the dipstick barb). There isn't much room but if you gently move the knife back and forth 8-10 strokes, you can cut it. Then install the check-valve. With this method, very little disassembly is necessary. Also, it may look like you should have access to this area by jacking up the car and removing the left front wheel, but there is not enough opening there, without completely removing the whole engine under-tray. The above described method was fast and worked great. Hope that this helps!

Very informational explanation! Love your details videos! Even my kids starts understand how complex systems works. Keep doing what you’re doing!

[@aftli]

You really seem to know your stuff. Thank you very much for your videos. They were very helpful this weekend for the VANOS seals and the lock cylinder rebuild! Especially the lock cylinder stuff - without your video I would have never known it was that easy to fix. Car is running *great* now, it now feels like it did 12 years ago when I bought it, and for the first time in probably 4 years I can finally lock it! I'm pretty sure I will have to do the CCV valve, so I'll watch this then!

[@50sKid]

awesome!

[@stewartcolley1345]

First a note of appreciation. Your videos are among the best on the internet. Good job. Please keep it up. Second, I am not a big fan of modifying stock engine systems unless you are going to go whole hog and prepare it for the track or some such other endeavor. That said, I thought your suggestion of putting a check valve in the oil drain tube was genius. But then again, maybe not. Or at least, it won't cover all possibilities. Let me explain. I just finished replacing my ccv valve. 2003 Z4. And it needed it. It was putting enough oil into the intake manifold that it was puddling in the air equalizer portion of the intake manifold. But here is the rub. The tube running down to the engine block, the dipstick tube, was almost dry. The oil in the intake manifold wasn't coming from the sump. It was coming from the valve cover by way of the ccv valve. The diaphragm had stuck wide open and all the oil rich air being pulled out of the valve cover was going to the cyclone and then up to then up to the intake manifold. The oil was precipitating out of the air in the air equalizer manifold much the way it should have been separated in the cyclone. Getting to the point, at least in my case, the check valve option wouldn't have helped. Anyway. You are a saint among KZbin video producers. Keep up the good work.

[@lycanzhp1141]

So that's how that handicapped octopi actually works! I'will be looking for the lower return hose to the oil dip stick tube now. That one part should be fairly inexpensive and easy to replace.. Thanks for your lessons man, keep rocking. !!!!!!

[@ChrisTopher-jv6ex]

i really enjoy listening to you. you speak clearly with good intonation.

[@paulthompson4326]

Great video,I learnt a lot about bad PCV,CCV systems when I owned a 5 cyclinder Volvo,they are notorious for issues with these systems,worse han Beemers , the check valve is a great idea tto prevent oil being sucked back up, but it must have a very low spring pressure else the weight of the oil trying to get back into the crankcase will not open it by gravity,maybe on an M54 it is better to drill a small hole in the part of the dip stick double tube section above the normal oil level line so if excess vacuum occurs, i will not suck raw oil,another note for anybody intending to delete CCV , bare in mind that these engines seals (rear main, front seal and all the noorious leaky gaskets)seal so much better with a negative pressure on the crankcase,my suggestion is to maintain the CCV,but mount the new one outside of the engine,say on your left inner guard area, extend all hoses to and from,mount it a same angle and height as it was under the intake manifold but outside of he manifold , your engine bay wont look as tidy, but cleaning and replacing the CCV in future will be much easier, BMW really did place it in a prick of a place

[@fortyfour6626]

Would you PLEASE buy an old 07 n-52 e83 and make these videos again? Your videos are the best. I am a weekend warrior mechanic and not very good. you explain things at a level real people can understand without getting to elementary. I just watched the whole dang video even though my CCV is built into the VC. I would be done chasing my leaks and problems by now had you just bought the same vehicle as mine lol! Great vids, thank you!

[@cherezuzin]

Thank you for your video. It's easy to protect this system in the areas with the cold climate - dont use the car during the winter for often shot trips. If you want to use your car for the few miles, just add to your shot tryp about 10-15 miles to "fry" the engine. And this system will be clean and the membrane will be intact.

[@billsilcott9692]

Thanks for the tutorial. You just set my mind at ease in a major way. I thought my X5 was going to have to be taken out to the pasture and put out of its misery, but now I am confident that it will be smoke free in a matter of hours.

[@1sobeit1]

Any news from your X5? Have you fixed it by changing CCV setting?

[@stonesthrow420]

I installed an oil catch can that is just chillin by my air filter. When I empty it, I just use a suction pump and a small tube. Takes about 2 minutes. Doesn't need to be emptied very much

[@stewartcolley1345]

I love your videos. Well done. Good information. And, the check valve modification is genius. If I may, you did the equivalent of putting a conventional (non-BMW) PCV valve in the BMW system. That is the sort of thing you would think BMW would have done, but perhaps that is asking too much. Anyway, another excellent video. Good job.

[@PaulCTownsend]

Thanks for clearing that up. I use oil catch cans on my GM 2014 and 2017 6.2 direct injected engines. Like you said they must be drained at about 3000 miles. Now that I understand the BMW system I think that's a great way to stay. I installed a hose on the bottom of my catch can and installed a motor cycle fuel drain valve draining is a lot easier. The motor cycle drain valve has the right O-rings so the crank case crap don't affect the rubber in the valve. The air tank drain valves do not last very long. Thanks for the great info. Paul's Transmission & Repair Baker city, Oregon love working on vehicles.

[@Poipounda007]

Thank you for an awesome channel!! I drive a E39 and replacing the CCV right now.

[@danadams797]

I like the addition of the check valve to the return hose. In order to combat heat degradation of the top part of that same hose, what would you think about wrapping an 8x4 inch strip of aluminum foil lengthwise around the critical section for heat shielding, then securing it with worm clamps? Aluminum does a great job reflecting radiant heat, which is why they use it in heat shielding near the headers etc.

[@edva135]

what about thermal heat resistant tape? wires are taped with this tape from factory

[@grandolddrummer]

That valve at the end there was clever! I think my old e46 is due for one of these repairs (along with a few others). Thanks and subbed!

[@engelbertmaier2853]

Very good explanation. Thanks from the Home of BMW. Bavaria Germany

[@seasonedtoker]

I think on these engines you could just stick a modified oil cap with a pressure gauge fitted, then start the car and note the measurement. If it is within -+0.03 bar vs. ambient air pressure (refer to nearest weather station). If pressure is significantly lower, then your membrane is stuck open or ruptured hose. If pressure is higher, there's a blockage or the membrane is closed.

[@vusimuzizondo3623]

50sKid you are doing a great job also when coming to explanation. I understood you there very clearly. 👌🏽

[@carlanthonym]

I appreciate all your hard work, thank you for sharing.

[@Raptorman5174]

Good video, I deleted mine on my 330i in favor of the oil catch can. Being in the north east the only problem I have had with it is when it gets cold the catch can fills up with water, so you constantly have to check it. In the summer You don't have to worry about it. I check it every thousand miles or so in the summer and there is a little bit of oil in there. You forgot to mention that the catch can increases crank case vacuum which gives the car a performance boost. I have been running the RAD OCC kit in my car for over two years with excellent results.

[@50sKid]

Nice, thanks for the info. I'm not sure increasing crankcase vacuum really actually provides any sort of performance boost, BUT i don't want to start a war over that, lol. Question: what is a RAD OCC kit?

[@Raptorman5174]

O my bad, this is the kit that I am running, its a bit on the pricey side but I love the mounting location the kit provides www.radiumauto.com/Catch-Can-Kit-for-BMW-E46-3-SeriesM3-P298.aspx

Dude your awesome! I now know way more than I need about my m54. Thanks your dope af!

[@louisdefilippi8982]

With my 2001 BMW X5 during cold weather I find I have to warm up these crankcase ventilation lines by running my engine at least 10 minutes while parked. I am not warming up the engine per-se but warming up the lines around the CCV so that I do not get the freezing and plugging effect.

[@elizabethkihara2668]

Love your videos! I'll definitely try your mod. It's a pain in the ass to change the CCV system.

[@mauriciocoura4167]

I have a BMW 328i 2000... that port ( vaccum tube) on the oil separator piece... min is not capped and is not connected to anything EITHER. Let's say if it is suppose to be connected to the fuel rail but IS NOT... is that why my car is running with rough idle on cold start?

[@nov8603]

hey 50's kid watched your video on oil filter gasket replacement very helpful was wondering if you were changing your front wheel bearings anytime soon would really love one of ur detailed videos all the ones I'm finding aren't really step by step like yours

[@50sKid]

I know that my driver side wheel bearing was already replaced. Not sure about the passenger side. But i'll put it on the list.

[@AdamAus85]

I did this job today. Took maybe 2 hours all up without removing intake manifold. Not too bad once you've made some room down there. Unfortunately the 2nd length of intake hose after the maf ripped apart as I removed it. Thankfully the best genuine bmw parts dealer around (Latvia + Lithuania) should send a new one on it's way real soon.

[@AdamAus85]

Also I was amused to find the cold weather version is simple the summer one, but with a nice little rubber/foam jacket.

[@tempest411]

Great video, and that's an excellent idea using a check valve in the drain line. The system overall looks pretty cheap though. What about a catch can, and running the drain from the catch can to the oil sump return line. You could plumb in the check valve you mentioned, or perhaps use a solenoid valve which defaults to open whenever de-energized, as when the engine is off.

Great explanation on how the ccv works!! Well done, your a smart man.

[@jameskipa2712]

I ended up removing the ccv system and routing a line from the valve cover port down to the ground to avoid smelling the vapors. I Sealed off the two small ports on top of the intake and put a cap on the oil return line port @ the dip stick. 6 months and probably 5 thousand miles later it seems to be runing ok. I'm no enginer- I dont know how much vacuum goes through the system but I need to know what and how much damage it might cause. # 02 E53 X5 @240k

[@Dancerman007]

im in about the same boat. did pretty much what u explained except i routed a hose up towards the intake from the dip stick so there can be some air flow. im just kinda wondering if im gonna loose oil and such by leaving the valve cover open like i am now. i considered putting a small pod filter on there but since its an output i dont think i need that.

[@vinthebin]

Thanks for the great video, I learn a lot with your detail explanation. For now I m trying the check valve , if the oil consumption stops or reduce then it will be great and is a easy job. I just worried the oil stuck in the hose .

[@Mark-th1gn]

I purchased a check valve and it looks similar to the own shown in the video, but i suspect the pressure needed for the oil to flow through is too high, i have to blow on it with some amount of pressure for it to open. Do i need one that opens with gravity or will the system apply enough pressure on the check valve so that the oil can flow down?

[@tommyhatem]

Very informative, i have a question , is there enough vacuum to open the check valve? I am afraid that the oil stuck on the tube and didn't go to the oil pan. Thanks a lot

[@dushk0]

A PCV is not a check valve! There should be no check valve. sure not one that is spring operated or vertically mounted. A free-ball type check mounted horizontally might work for a while. A PCV valve is normally open. The flow gets gradually restricted as manifold vacuum raises, mostly on idle and near idle (PCV system is not meant to suck up oil vapors, it is meant to suck up blowby and water vapors). The central exposed piece of orange rubber is not a seal, it is meant to tear if the oil sticks up the valve, acting then as a fixed orifice PCV and a vacuum leak that shows engine light. Older PCVs acted as a check valve against backfire, these new ones don't protect against backfire at all so back to point one - it is not a check valve, ever. Listen to this guy and ruin your engine for good, he can buy parts, follow a manual but he's a parts monkey with no real understanding.

[@ArtSkoolDropout]

@@dushk0 pretty sure he is talking about the check valve he installed for the oil, not the CCV itself.

[@ChrisTopher-jv6ex]

@@dushk0 you seem to have a better understanding of the system, please make a video about it. i get the occasional engine light because of p0171/0174 and the engine often stalls when rpm approaches idle. should i replace the whole system then or just the lower tube which might have cracked?

[@erikalvarez4516]

Can I troubleshoot this by loosening my oil fill cap to ensure it's a CCV vacuum issue? I have the typical VANOS and half power mode after 20 minutes of driving. I have noticed my oil fill cap has a strong vacuum and I want to be 100% sure it's my CCV/ valve cover assembly. Can I loosen my oil fill cover to have a better vent and testdrive to see if it makes a difference?

[@patrickcunningham359]

I have the yellow mayonnaise in my CCV and I also have white smoke coming out of the exhaust. Do I have a blown head gasket?

[@mosesneri5060]

I had the most common broken hose you mentioned broken. It was broken during extreme cold and high humid weather. I did see a little yellow mayo. I didn’t open the system to check for mayo. Would a bad ccv make a hight pirch noise at cold start only? It only does it for 5 seconds and it goes away.

Good insight. I’d stay with the oe setup. the problem with aftermarket parts store pcv hoses I noticed is that they crack too soon for some reason. I discovered this on my Oil Catch can set up on my 4 cyl M44. So for my M54 I kept it the same.

[@joeybaaklini683]

Hey man i did replace the ccv and tubes but not oem parts and make the o2 pilot mod but car still burn oil . Then i did remove the return oil tube that goes to dipstake and turn on the car i notice that there is little of vacuum in it does that means a bad ccv ?

[@busterscrugs]

What about a catch can with the drain routed to the dipstick tube (where the stock CCV drains)? This is what my friend did on his E39 530i and I'm thinking about doing the same once my CCV fails, since a catch can will never fail like the CCV diaphragm does.

[@horrysands886]

So I don’t have to take of the intake manifold for an n42 motor?

[@markbohannan]

Watched your ccv delete video. i replaced my system with my starter replacement. Should I consider the delete?

Hi 50s KID, Can you help me please? "I replaced the valve cover gasket and after starting the engine, it started to hum and the engine ran as if a cylinder was misfiring. The humming noise comes from the CCV tube that goes into the valve cover. When I disconnect it, there is pressure coming from the tube that causes the humming. When I block the tube with my hand, the engine runs well. Do you know how to solve this problem?" Thanks Joseph

Jus random but ive heard some cheap metal valve covers arent ported right. The holes in mine werent drilled out at all.

I have a very strong vacuum when opening the oil fill cap. And the car is nurning a lot of blue smoke when accelerate or long idle. Will cutting the dipstick hose and apply this mod solve tje high vaccum and smoke or will it only stop the smoke but still vacuum a lot?

[@thechronic555]

Wont stop vaccum but the oil in the exhaust fumes will prolly just build up until it clogs the intake i suspect.

@@thechronic555 oke thanks for info

[@masterbruce1546]

Hey so you know that hose from the dipstick the one you said was the main one that rips. Well I had found that mine was torn like you said so I did the whole ccv system change and white smoke would still come out I drove it for a while and it stopped coming out. Was the the problem that was causing white smoke??

Hi there, is it absolutely nessesary to have an inline pcv valve when using a catch can if I'm not draining back to the sump? Z4 e85 m54 engine.

[@Anonymous-oi5mq]

Hey boss so I've been watching all of your ccv system replacement videos and deletes and swaps to catch can but one thing I haven't heared you mention is the tiny little Port that leads to the fuel rail. So my question is what happens to that hose when replacing the ccv with a catch can "which is not what I'm hoping to end up doing" but what do you end up doing to that hose do you seal it off? Or do you vent that hose Into the catch can? But my particular situation calls for after the 4th time removing my mainfold after replacing blown heater hose and then new starter and a few other odds and ends I figure out that my ccv was completely destroyed on the inside the black seating piece under the diaphragm was nothing but little bits of broken plastic when I took it off and I went to the parts store to get a new one and I suppose there was a misunderstanding and he ended up selling me a pcv system for my car instead of the ccv which I didn't realize had happened until a while later after installing the pcv system and then sitting there for about a week scratching my head looking for that tiny little mother ***** valve port that happens to not exist on the pcv system 😢 later from watching your videos I figured out there's a difference from the two systems can I just replace it with the pvc valve it has all the other connections besides that little tiny port and if so what would I attach that hose to or would I delete it? That seems a bit risky to me to just fully delete it but you clearly have a much better understanding than I do about these cars. And my car is a 2000 323ci with the m52tu engine in it. Please if you have any information, hints tricks tips anything on what I can do at this point I'm really not wanting to retake off the whole manifold yet again if I don't have to Thank you so much your videos are definitely grade a information all the way I definitely appreciate what you do here on your channel thanks again

You can leave it open. It’s not for applying vacuum to the fuel pressure regulator. It’s just in case the diaphragm in the regulator degrades and fuel vapors leak. They would get routed into the intake through the little CCV port.

[@50sKid]

Oh I just saw you have the m52tu. In that case the fuel pressure regulator IS vacuum referenced and that vacuum comes from the back of the intake manifold. In that case the CCV port is blocked off by a rubber cap

[@Anonymous-oi5mq]

@@50sKid so that would mean the port on the back of the mainifold is where I should connect the 2st line from the fuel rail is that correct? And thank you greatly for responding I really appreciate it.

[@50sKid]

@@Anonymous-oi5mq Yes

[@MediaEasier]

If you do a vaccum oil cap test, should the cap be hard or easy to remove if the ccv is faulty?

[@emilioquiroz5734]

can a bad one cause a carbon or burning smell inside the car i probably will replace it cause the car got over 1786000 miles but lmk if that’s the case thanks

[@hugogarcia6318]

Thanks for the explanation 50's kid!! awesome video, finally understood how it works!! any part numbers or details about the Check valve?
