Apologies for the video being rough, bit of last minute thing. Hope this helps! Fairly straight forward DIY task - lack of space is the biggest issue.

Great video man. Very straight to the point. well worth the 5 min.

[@jamesmcilroy9273]

Awesome video, just been fixing mine using this! It's a tight fit, and crap if you haven't got slender hands. Getting it out was ok, but the amount of swearing trying to get the new one in, now that was spectalular... I'd advise anyone to hold it with pliers in position, then screw in with your other hand, then quickly use the tool by hand to screw it in enough to have to start using the ratchet. Glad I've done it though, and this video gave me the confidence to, so cheers! Awesome work!

Mpower22 lol i got the tool and O rings from the same guy to fix my leak here in the US..CHEERS!! good Vid.

[@y2ksierra]

[@TheMaldenc]

Perfect, detailed, straight to the point! Thank you!

[@Haider_Malik]

My pleasure Sir :-)

[@aksman1964]

Thanks for the video, really helps me out 👍🏼

[@Arsenalusa]

Thanks for posting mate. The BMW dealer here in san diego also referred to this as the "engine euro valve".

[@Haider_Malik]

Your welcome :-) Great to know, I'll add it in the description.

[@yruhatin100]

Same here in Phoenix

[@SteveMillerhuntingforfood]

@@Haider_Malik Thanks for that, now I know what the BMW dealer is calling a "Euro-Valve". Sterling BMW in Newport Beach, CA wants $1000 to replace that valve. I'm truly offended.

[@l0lwut123]

thanks for making a video of this. i read the writeup by heckafunctional on m3forum and wasnt sure how to get access tot he bolt even though i bout the socket and the viton o rings

[@Haider_Malik]

No problem at all. Glad you found it useful! Good luck :-)

[@eduki]

Heheh, It was my first fix to do on my M3 :) i did it the same way like you did, but later i helped to other friends with this and it´s much more easy to access with these short kind screwdrivers with the same kind of tip at the end (i´m sure you know what i´m talking about) This way you can access on the same spot with your hand, don´t have to have a hard time trying to place the ratchet ;) NIce DIY ;)

[@Haider_Malik]

Hi, Yes seems to be quite a common issue - damn O rings! Great tip, would have made my life easier lol Thanks for sharing :)

[@kuruption1983]

It definitely helped me despite your belief :D

[@p.doetsch6209]

What are the symptoms that would indicate it needs replacement?

[@LateNightRituals]

Nice

[@MyRcGoSlow]

Would this fix a p0011 ?

[@isrealperez9069]

Is this only for m3 only I have 2004 bmw325xi

[@robertabalos3353]

Do you know if 2005 X5 3.0 M54 engine is also equipped with this CPV? My X5 also has leak symptoms in the same area.

[@Haider_Malik]

Robert Abalos Hi, unfortunately I’m not familiar with the M54. Find the parts diagram on realoem and check if it does have a cpv. I hope you find the cause of your leak 👍🏽

[@MrJakk]

Look at you mr mechanic ;)

[@Haider_Malik]

MrJakKiD as if you saw this 😂 cheers mate

[@emilepapillon2275]

How much did you tighten ? Approximately ... qualitatively ...

[@Haider_Malik]

Emile Papillon Torque to 58Nm or 43ft-lb then turn a further 90 degrees. It’s difficult getting a torque wrench up there so I just did it free hand based on feel. Still holding up fine over a year later.

Hope this helps! Links in description.

[@luiscorrea2909]

Thank you for sharing the information.

[@Jdmbuilds]

Are these only for m3 or are they Also on m54 motors

[@Haider_Malik]

I believe its only applicable to the S50/ S54

[@Savorychicken41]

That flat head took is from Harbor freight. Super cheap for a whole set.

[@Haider_Malik]

Great to know, I wish we had Harbor Freight in the UK.

[@fearthereaper5663]

Hello this can cause burning oil smell ? Thanks a lot

[@Haider_Malik]

Yes in some cases if the leak is really bad it can drip onto the hot exhaust manifold and burn off

[@fearthereaper5663]

@@Haider_Malik thanks a lot

[@fearthereaper5663]

@@Haider_Malik but it seems that the nut is below the exaust manifold . Is correct?

[@Haider_Malik]

@@fearthereaper5663 It could also be a leaking rocker cover gasket at the back or side of the block. This oil could definitely make contact with the exhaust manifold. Do you have oil marks on the floor where the car has been parked?

[@fearthereaper5663]

@@Haider_Malik yes a lot

[@juice0wnzzz]

Did the oil need to be drained in order to do this?

[@Haider_Malik]

Johnny No need to drain the oil. As long as the engine is cold very little oil, if any, will come out.

[@juice0wnzzz]

Haider A thank you, I great appreciate it!
