Don't Forget Your PCV Valve! | BMW N54 DIY

- This is a quick video showing you how to upgrade your PCV valve on your N54 powered BMW. I'm working on my 2008 BMW E90 335i.
The stock PCV valve is made of plastic and can fail on you. It can cause a boost least which will pressurize your crankcase or cause your car to burn oil and smoke out the exhaust.
If your car is tuned or high mileage it would be a good idea to change this piece before it can become a problem for you.

I can watch ur videos all day
For my e92 n54
Straight o the point
Great Video. When I replaced mine, the old one was stuck inside of the housing. Had to use a long nose plier with a 90 degree vent to work it outof there.
Yep did it with my valve cover change recently watching your old video lol
Thanks for this Video!! I ordered the upgraded valve for my N54 just haven’t done it yet! I hope this helps!!
Yep, I had forgot about the good old pcv valve. Time to switch it out, thanks for the link!
Your best bet is to do your High and Low side PCV to catch cans as well. A DIY for the low side with port blocking would be awesome content, but may not be in your best interest if you have done any valve cover work recently.
awesome video Man
Replaced mine just now, didn’t fix the start up smoke, but was an easy install
Yup I upgraded to the RB pcv valve myself ive got an e92 didn't have to remove any fuel lines though. Fast easy, cheap also see a lot less blow by 👍
Can a bad pcv cause the car to smoke through the exhaust?
Thank you sir love these videos clear and accurate
good video as always. thank you
Changed my valve cover gasket and didn’t do this now my cars still smoking but deff gonna try this
I just changed mine on my fbo n54 , the car was starting very rough and consuming oil at a high rate and didn’t feel normal under full load , i got a metal valve from Burger Tuning and the car feels a 100% different, I can’t believe that little neglected valve can make such a difference.
can you add a link to what you purchased? Might need to try. thanks!!!!
@@kristinrichner2528 he literally said it's from burger tuning
@@thinkingagain5966 harsh, but justified
@@thinkingagain5966 And I literally found it and literally changed it out. It litterally may have helped a little. Have a literal great day.

A word of warning: I changed my stock PCV valve for an FTP brand PCV valve and added a BMS oil catch can to my N54 almost a year ago when I walnut blasted the intakes. Upon completion the engine began making periodic screeching sounds like metal on metal with no lubricant. My hearing sucks and I have tinnitus so locating the source of sounds for me is next to impossible. Long story short, turns out the sound I was hearing was air being sucked into the crankcase past the front crankshaft seal. I spent a few weeks before I figured that out and spent a few hundred dollars (which would have been a couple thousand dollars had a repair shop done the work) only to find out it was a faulty PCV valve and I should have known better as the instructions were useless and it was made in China. I had purchased this from the now defunct BavAuto who blew me off when I tried to tell them about it. In short, buy a quality valve from VTT or RB Turbo (where I got mine) and know you're getting a well made product. The results are worth it.
Rrudy DeDogg did faulty PCV create more vacuum in the engine? Have you tried removing oil fill cap while the car is running?
Very nice upgrade, and when Jakes one is holding up, it's a great upgrade :-)
Was thinking about doing this, now I can!
Thanks great video! Im pushing 22 psi and burning oil, already ordered my catch can this is my next purchase hopefully resolves my issue.
Hey man did it work? Mine smells like it’s burning oil and I just did my valve gasket
@@bakerhead_ sell it bro 😂
@@outlaw8388 dang man just got it a while back too😭
@@bakerhead_ fix issues and sell it i put over 8k into mine with in 10k miles definitely not worth it
@@outlaw8388 damm bro. Thanks tho I’ll see what end up doing I’ll lyk
Very useful info.
I have a 2008 335XI N54 model (w/74K miles) and getting an oil leak dripping on the exhaust manifold (Note: the area is on the manifold to the left of where the PCV is located near the firewall area) and the valve cover does not seem to be leaking. Can this valve or that oil blow back tube be causing the a leak to cause this issue?
Again, well done video. Thanks.

Doing this with vac lines hope it works 🙏
Just upgraded my pcv to a BMS unit and I do NOT recommend cutting the burrs on the PCV cap. I did that and it caused a bunch of weird metal whirring/rattling noises. I ended up needing to buy a new metal pcv cap, which solved the issue. If you're having issues fitting your new PCV: 1) make sure you lubricate the rubber gaskets with some engline oil and 2) if you absolutely need to trim the burrs, use course sand paper and only remove a little at a time. Hope this helps save people from the same headaches I just went through :)
I actually bought Vargas PCV valve and it is not fully seating on the cap. I read on forums that if you trim the cap, it may cause boost leak. That's why your comment caught my eye, did you trim the inside part of the cap or the outside part? I think if you slightly trim the inside part of the cap with sand paper as your describe, it may be a viable option. Where did you buy your metal cap? I may be interested...
If you buy Rob Becks version, he sells an aluminum cap that fits his upgraded PCV valve.
Also, the PCV breather valve hose should be replaced every 50k or excess pressure can build up & cause valve cover & RMS leaks.
I just ordered hw rb pcv bro just like 10 min ago
Have an oil leak, took it to the mechanic and says it was leaking from the crank seals due to a defective pvc valve/pressure build up. Said the pvc was integrated into the valve cover and the whole valve cover would have to be replaced/1200 repair. Of course your video shows otherwise. 🙄Can you provide and updated link for the upgraded part? The one you posted says the part is no longer available
Sweet.
Do you think that a bad PCV can cause enough pressure in the crankcase to cause an oil leak on the front crank seal?? I would a appreciate you opinion thank you!!
hi thank you for the vide. I looked simple enough to attempt om my own as preventative maintenance. Based on the rodeo it was easy enough to get there an remove the PCV valve cap but the PCV valve will not budge, come out. of course the only way to crab it and try to wiggle or pull it out is though the small plastic stem and it broke! Any Ideas how to get the old valve out????
Would you recommend upgrading PCV valve if the tune does not exceed 18psi? Complete valve cover is brand new, should I leave all it as it is?
i have a bmw 320d which when i give it a cold start, it will smoke a little and smell too. also i dont feel it have the same power it did years ago. changing this will help?
I have an oil catch can and with that I believe it deleted the pcv valve... Is that good or bad??? What do you think about running oil catch cans??? Thanks
Did you also increase your hose diameter? Silicone or rubber? No catch can, correct?
Do N52 have the same PCV valve? I'd like to clean it?
I changed my pcv valve with an ftp valve. The car now smells of oil especially coming from the bov on my chargepipe. I’m losing oil but at a very slow rate. Any idea on what’s causing it?
So I keep getting the dreaded P0171 and P0174 codes. I opened the oil cap to check for suction and there was none. What I did notice was the oil cap wasn’t seated properly. I reset the codes and it has been running fine for the last week. Could it be that simple?
Can you please add the link to the pcv valve again? Thank you
What is the BMW reccomeneded Torque spec for PCV valve?
Hi, is this the same process for a 318d e91 ?
Does the thread of the new upgrade valve have to be screwed tightly or a little loose? Does it rattle when you shake it back and forth?
When its bad, does it have a howling noise?
What if you have a oil catch can?
any new link fot the part?
I just had Downpipes installed now exhaust is blowing some smoke
Hey, you. Thanks.
Is it works for BMW X6 2008 E71 35ix n54?
Can a bad pcv valve cause the car to smoke ? Thanks in advance 🙏
So i have a n54 e90. has docrace 6266 on it. my question is around 55-6000 rpms ill notice it doesnt hold boost it slowly drops down to 23psi from 26.5-27psi it starts at. Would this be the cause? i done a smoke test and the pipe that goes into the inlets smokes like theres a vaccum leak starting to think that its leaking cause loss in boost. Is that possible
Hi, I break the PCV cover and I can’t take it out, can you help me?
Anyone have a new link for this new PCV valve ? His link doesn’t work anymore .
Could the car smoke due to bad pcv valve
Hey I hope you still answer do you know any new links for the pcv the old link doesn’t work anymore
Got link where I can buy thx
Is it necessary to put back an engine cover ?
This and VTT breather oil cap seem to have made engine blow-by less. Less oil in intercooler piping and such.
Adam Humble could you post a link to this product or just tell me where in the engine bay it is? I’m doing process of elimination my n54 just started smoking a bit

@@jdbenson1 thanks a lot man!
The link to the item not working can you send me another?
pcv on n54 is hooked up pre-turbo... can't cause boost leak, but can cause excess oil to enter the turbo, resulting in smoking issues.
Was going to ask that. How could a pcv malfunction cause boost leaks.
Next time you do a valve cover gasket and walnut blast, convert to an external PCV system. Let’s you run a catch can
We need the turbos update! Lol. My stock turbos are almost on there way out and I’m in between these or the proven ps2’s.
These have 3 stages check out their website
Dynamicautowerx.com
They're awesome, the reason you haven't seen a dyno video or an update is I was having a misfire issue but that was resolved by updating my ECU to MSD81, it instantly told me I had a bad o2 sensor and it's running super strong now. I'll get you guys that update video soon.
Vehicular DIY awesome man! Thank you. Glad you resolved your issue.
No entiendo, esa válvula es la pcv?, Hay otra que es circular, viene en 2 piezas, va por el maniful, cuál es entonces la pcv?
How long was the car shut off ?
Is this the same location as the n53 engine?
So ur car doesnt have the both orange cylinders??
PCV valve replacement is also important, because if it sticks open, the car may behave like it has a vacuum leak.
Does it sound like there's a howling noise?
@@beamerandthebeast3979 I don't know. I am used to PCV systems on American and Japanese cars. Those systems don't howl. It might be different on other cars. Does your car have a turbocharger? Maybe there is a leak from the BOV/Bypass valve.
@@skylinefever same car, n54 ftw, but its making a howling noise and only holds 4 pounds of boost
@@beamerandthebeast3979 It could be a BOV or some kind of pressurized boost hose. Sometimes an intake hose will only leak under pressure, not under vacuum.
@@skylinefever it was a screw that fell into the inlet that ate the turbine when he was replacing his chargepipe and dcis lmao!! He's a potato
Where I can buying
Hey VDIY love you videos!! Anyway I’m catless downpipes right to catless straight pipes. Every since I did those mods I’ve been having a blueish smoke coming from my car usually only on deceleration? Think it’s possibly Pcv or bad valve seals?
Im on the same boat. Didnt smoke with cats, now it does it when I come to a stop. But wont smoke as much or at all if I downshift coming to a stop. PVC?
@@thisguyshorty3554 i think i will just replace my pcv valve soon and ill get back to you with results. i have to say though ever since i got mhd and tuned the car to be catless im getting minimal to no smoke at all now only on an occasion under vacuum
Justin Spanabel did you ever find the problem? I have smoke on decel and when I left off the gas only
I've had the same, original exhaust for 3 years, never a problem. Now Eismann exhaust, now smoking and fat/wet rear silencers. I have another PVC valve from FTP. What should I do?
Thank you sir! I just bought the rb pcv after watching your video since I also got the dynamic autowerks turbos but the 775rs ones they're coming in a week or so. Am so excited. I really want to see the dyno or track numbers of your turbos. How are they? Pulling strong?
Hey man, I see you mentioned dynamic auto works turbos. I ordered n54 stage 2+ turbos about 3 weeks ago... still havent shipped. How about your order ?
@@acauto7886 they will be soon bro mine says should be here on 17th. Yours as well soon. The seller is 100% cool and replies in like 10 min lol hit em up he always answers to me. You got the 17.5t as well? 775rs? That's what I got too. Your car will be fast and hell soon bro I seen the 730rs (our us 775rs) do 129 mph on quarter mile here on RUclips on 25psi only. I just cant imagine how crazy these will be on 25 psi. But I'll be at 20 or 21 for now on e40
@@ALEX.THE.RUSSIAN yeah man. The company is great. They respond to emails in 20min tops. But I got the stage 2+ 775rs too. Just waiting about 3 weeks so far. I ordered it August 20th. It's now sept 15. I spoke to them over email they said hopefully 2 weeks max. Did u get the upgraded inlets and outlets too?
@@acauto7886 I ordered about same day as you somewhere around there. He just said they didnt had them at the moment to be shipped out. But they will this week so they shipped mine out I guess. Yeah I got the stage 2 + am hella excited you have insta?
👍👍👍
Have you considered going external PCV to eliminate oil in the intake runners from the oil drain ports in the head? I put in an aftermarket valve a while back, and while I'm not concerned with the valve being overpowered by boost, I still see a decent amount of buildup around the intake valves...
Dick Suedkamp external kit is very good and if you are confident cleaning your valves you can manage plugging the head ports
Just took order of the same upgraded turbos as you, but I'm worried about fueling. I'm running straight 94 octane, as E85 isn't available for purchase in Southern Ontario (Canada). Any suggestions on how to optimize my setup?
abdul_e92 the fueling should be near stock for the ones he got. The seller mentions to get it pro tuned!
Did you buy from eBay or their direct website?

@@erickromero010 I ordered their 775rs one recently bei
would you do this if you were also planning on doing a oil catch can system?
No you don’t need this if you do an external PCV on the low side
Can that work on my 740li bmw2012. Anybody
I have the same valve in my 750whp 135i, holding up great!
weird flex
Did you get that sponsorship yet!?
Just creating click bate.
@@Alboy98 nigga that was a clean ass flex
@@ALEX.THE.RUSSIAN yeah, definitely a clean flex lol.
Do you still recommend if valve cover is new
Yes it will eventually break
Forgive me for asking what maybe a silly question, but what kind of grease do u use to lube the o ring
Most likely just a dab of engine oil
You got it, a dab of engine oil for the green sean and a bit of silicon grease on the smaller oring. Engine oil would have been fine for both.
I don't NEED a oil catch can in addition to this, do i?
Have you found an answer?
Do you know if it would be redundant to buy and install the PCV if I'm installing the catch can?
No I wouldn't consider it redundant. A catch can helps but the upgraded PCV helps with holding boost.
@@VehicularDIY I keep hearing about a high and low side for different catch cans... so do I need a second one or Is there one that does both?
I have stock turbos on my E93, it’s 102k should I go ahead and change it. To prevent any leaking. ?
If you're due for a valve cover gasket that might be a good time to tackle this as well.
With how old this video is, I don't know if you will see this. I have an issue with my 135i whenever I am coming down to low idle. Whether that is coming to a stop at a stoplight or after a small rev while in park, my car will either cutoff and need to be restarted. It also has a delay when I press the throttle to where the car will jump after a few seconds delay to get going. I wasn't sure if this little piece might be the issue or not, but my mechanic and I have replaced coils, spark plugs, valve cover, and valve cover gasket. I also had the alternator replaced around a year and a half to two years ago, for complete loss of power issues. Im at the point of being stumped. Any suggestions?
fuel pump
they still leak stock turbos mine smokes like a chimney
My car smokes for a few seconds when i idle with the car after a good pull sometimest blue smoke could that be it? my turbos are spooling just fine?
The turbo seals could be on the way out. How many miles are on the car?
Should these be upgraded as a matter of course, even if low miles engine with no issues?
@Capt Hook all done :)
Your ebay link is broken.
does this also work for e90 323i?
The PCV system here is specific to the N54 turbo from what I can tell.
I think you mean don’t forget your external PCV kit requiring removal of the valve cover and plugging the head ports. It’s much more comprehensive.
Can you please elaborate.
Mad Dog google “rb n54 pcv kit”
@@Bikeadelic thank you
Mad Dog oh O forgot I actually did a write up about it on “bimmerforums”
@@Bikeadelic I'll search for it
Just cracked the cap, any ideas what to do ?
Order a new one
Yeah you can get new caps just look around junk yards or wrecker lots etc probably cheaper than ordering online but hey just an idea idk
If you want to save $40 and I didn't have to trim the pcv cap to fit. The one I bought had a genuine toyota PCV valve in the box, if you remove that metal ring on the RB that's what you will see...

Does the 2008 328i have the same valve? N52 engine
no its built in to the valve cover i believe

Hey I snapped my pcv valve cover where the valve sits in I'm having trouble finding a website that sells them know any places

The noise ended up being a small boost leak that happened right after the pcv replacement.. I bought the BMS one and no issues..
@@shaunpilkington4625 is the leak because of pcv ?
I got 80k miles on my 335is. I’m looking to do this because my car throws smoke from my car when I turn it on after a 2nd time. I do a cold start and drive, no smoke. I turn it on again and I’ll stop at a light, step on the gas alittle and light white smoke comes out and it looks like a lot. Turbos sound healthy so not sure what it could be... can this pcv valve really cause that much smoke to come out of the exhaust??
I had the same problem. Mine was burning a lot of oil. It turned out to be the turbos.
Where was your problem ? PCV valves fix it ?

I had recently replaced my PCV valve, same one as this one. About 2 days later at cold start up I got a slight white/blue puff of smoke and then it cleared up. It only does it cold start up. Was wondering how yours looks like after u got it tightened down all the way. I feel like mine is not perfectly flush but at the same time I don’t want to crack the plastic fitting.
i have this same problem i have a 320d, i was thinking that changing the pcv will make that problem go. also it doesnt have the same power it had before and is also consuming more diesel
