Thanks for making this video. I did as much research as I could after getting my ‘16 340i almost 2 years ago and have been driving around with a pcv diaphragm in my trunk for almost 2 years haha. Well…Today was the day. Luckily and unluckily I was right in front of Walmart and was able to grab what I didn’t have. I had a general idea of what I needed to do, but watching your vid while grabbing parts helped me knock it out in 10-15 minutes.

[@trevorjelam]

Nice! Glad it helped out

[@defyyourlogic487]

Ik this is an old video but this shit saved my life. Just make sure not to crack the old cap in case the new one doesn’t fit. Piss easy job took me less than 5 minutes.

[@AntBuilt575]

Also, it comes off easier when car is warm. Found out the hard way

[@trevorjelam]

I think that was the reason mine shot off🤣 car was only off for 20ish minutes

[@BurrNinja]

Thats cool its actually serviceable vs the built on crap.

Awesome video I fixed my 540i 19’ like this

Love taps around the ring 😅

Goodd morning, excuseme i have a question... is necesary clean something, after to replace de pcv? or replace the valve only. thanks!

[@goatcardz1267]

did you have to cure the gasket maker on the cap before installing?

[@crumdoggy]

Thanks so much!!!!

[@the_batmobile0.4]

Wouldn't the gasket sealed made it impossible to take off if needed?

[@jamesbarber8308]

No

[@piersonsherley7888]

How long did you drive it messed up? I’m scared to drive mine until it comes in

[@B58Kepple]

I’m having the squealing whenever i accelerate no smoke

Does this work on S55?

[@syke008]

Great Video thank You! How do I know what Gen my B58 is? Dealer wants 4k to replace the whole cover! 2016 340i M. Thanks

[@trevorjelam]

2016-19 is gen1

[@jarred.official]

How were you sure it was the PCV and not the turbo seal? Just trying to be sure before diving to deep

[@trevorjelam]

Pcv is $40, replace it to easily figure out which it is, link in desc

[@DamnDudeGetaLife]

I replaced my entire valve cover when this happened to me because there was not a kit available at the time....

[@tontom4822]

Hi mate Any update on that Hybrid Turbo you were testing few months ago???

Im having the same problem on my 2018 540 (B58) is it the same process to replace it? Or is it the whole valve cover?

[@Xavier-hernandez]

same procces but the cap my be slight smaller since your a g body

[@johnvthvn]

can’t find the aluminum cap on your site

[@DarkKnight_2324]

Had my 2018 M140 at the dealer today. They want me to replace the PCV valve as well as the valve cover (apparently you can't replace it separately). Symptoms of mine was the smoke and oil consumption.

[@trevorjelam]

This replacement is done instead of replacing the entite valve cover. Bmw dealers make more money replacing the entire cover

[@wordlife_97]

@@trevorjelam is it required to replace the cover?

[@isaacdavis9573]

@@wordlife_97on gen 2 b58 yes since the pcv diaphragm is built into the valve cover but yours is gen 1 so no you don’t have to replace the whole thing

How about a 2018 740i? Do I need to replace the whole valve cover??

[@isaacdavis9573]

@@sharifhrivers nope just the replace the diaphragm

[@BumpytheBench]

Do you let it set for the full 24 hr cure time or do you think, just over night as you stated is good enough?

[@trevorjelam]

I would definitely do overnight as a minimum, but 24hr like instructions to be completely safe

[@almirsahinovic9275]

I’m doing this as a last minute repair. This is my only car. Is it safe to drive the car a few hours after applying the RTV? Or is over night mandatory?

[@underachv]

@@almirsahinovic9275 what’d you end up doing for fast repair? Just slap it on and drive it?

[@oscaromana9062]

Is this the same thing for a 17 540i? Just want to make sure before buying the part

[@trevorjelam]

Yep!

[@codycooper8105]

did this fix stop the smoke

[@antoniocarrion340i7]

Just installed. Letting it cure over night. I hit it a few times but i was able to pull it up with my hands when i try hard. Is that okay?

[@trevorjelam]

You may need to get one of the metal caps we offer if it doesnt stay on after tonight, it should fit snug with even pulling on it.

Er, no thanks - I'd replace mine with the OEM one. One would think they'd design it easier to take off and replace though.
