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

[@abelucious]

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.

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.

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 👍

[@homeromata9202]

Can a bad pcv cause the car to smoke through the exhaust?

[@rrudydedogg3779]

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.

[@russg2279]

Rrudy DeDogg did faulty PCV create more vacuum in the engine? Have you tried removing oil fill cap while the car is running?

[@adamjakubowski8750]

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

[@p_dubski]

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 :)

[@c.c7263]

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...

[@fistacuffs_gg]

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.

[@DkKristie]

Yep did it with my valve cover change recently watching your old video lol

[@ParadoxPWR]

My N54 smokes when in low rpm load and gears (2-3). When I do a pull 6-7k rpm, in gear 2-3 I get a check engine light calling out a “boost leak”. Will get back to this when I change that valve.

[@datzlukeh2627]

Thanks for this Video!! I ordered the upgraded valve for my N54 just haven’t done it yet! I hope this helps!!

[@micraw714]

Yep, I had forgot about the good old pcv valve. Time to switch it out, thanks for the link!

[@sergeyobrezha6780]

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.

[@MygenteTV]

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

[@AlecKristi]

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.

[@Capz0r]

Was going to ask that. How could a pcv malfunction cause boost leaks.

PCV valve replacement is also important, because if it sticks open, the car may behave like it has a vacuum leak.

[@beamerandthebeast3979]

Does it sound like there's a howling noise?

[@skylinefever]

@@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.

[@beamerandthebeast3979]

@@skylinefever same car, n54 ftw, but its making a howling noise and only holds 4 pounds of boost

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

[@matthewweisdorfer7757]

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.

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?
