How to replace the PCV Valve with attached pipes.
For all M54 inline 6 BMW engines in any model. From 2000-2006
-About the PCV valve..
PCV Stands for Positive Crankcase Ventilation. It's job is to allow the crankcase to breath and allows the engine to re-burn fuel vapors caused piston blow-by. All while separating the oil vapors and returning them to the oil sump.
It uses a diaphragm to aid in this job. When the diaphragm brakes , it causes the engine to consume too much air. Which makes the engine run rough and set a check engine light.

Nice video Man. This is so far the best detail explanation on how to do it without removing intake manifold. Amazing content. Thank you ! 😎💪
Appreciate it!
Thansks for your video, it´s clear and straight and it will be very useful for me. My ´01 530i runs great but burns 1 liter of syntethic 5w40 every 250 miles. Yesterday I checked the inside of the dipstick tube guide (it was clean) but realized the hose that returns oil from the CCV to the oil sump was completely dry inside, so my guess is the CCV must be clogged and sending the oil to the combustion chambers. I think I must replace the CCV and tubes.
You skipped the part how to connect the corckscrew tube to the valve. How did you connect them?
thanks for the video, very well explained, 👍
Glad it was helpful!
I say thank for worchin this video
Great and detailed videos is this the same procedure on a BMW X5 2016?
Thank you. It is different on your vehicle.
Nice work! Realistically, how long does this job take without filming?
I usually average 3 hrs all said and done. My first one probably took 4. Its not bad. Just take your time. And take some pictures along the way just in case.
Can an overdue oil change cause white smoke from exhaust?
No. Worn piston rings and valve guide seals can cause oil to enter the combustion chamber and cause smoke from the tail pipe as well.
i have an 04’ 325i that i just bought. 2nd cylinder is misfiring, and it’s idling pretty rough. we know it’s not spark plugs or coils. would PVC be my best bet?
Only one cylinder misfire makes me think it's something else on 2004. Could be a faulty injector. Can you verify you are getting spark? If so then verify there is power going to the injector. If not then it could be a faulty engine control unit.
What is the thin line you took off by the fuel injectors. You had to unplug a sensor the move it and also it had to fittings. You showed it at 7:27 in the video
Some engines have a cold start fuel injector. Most do not have that.
So a bad PCV and PCV pipe will make BMW run rough with misfire and produce exhaust smoke ???
Older engines it will misfire and run rough. Some of the newer engines it will produce smoke from the tail pipe too.
@@MikeMDs Mine is a 2009 535i i think the complete PCV system is shot or bad turbos, vacuum leaks .Its showing PO171 code misfires also i think the coils spark plugs are shot..
Do you have to disconnect the battery for this job?
I do every time messing with and electrical like unplugging anything just in case. (Don’t want a code like airbags do).
No you dont.
Fixed my issue....was driving me nuts....
Annnndddddddd its back....throwin lean codes....FUCKKKKKKKKKKK
You may need to smoke test the induction system. If all looks good I know the DISA valve can cause lean mixtures. Also the fuel pumps on these older ones. And sometimes the mas air meeter.
@@giantclam1822 did you fix it?
@@high_monkey nope
With brand is it pcv? Geniue bmw? Cold an warm climates?
Its genuine bmw. Usually if you order the cold weather kit it is cheaper. They both fit the same. You can peel off the foam covering it when installing. Assuming your car doesn't have the cold weather package.
@@MikeMDs How much does this set cost ?
@@MikeMDs give me adress link
Could a bad pcv cause the car to smoke on start up and during acceleration?
What engine do you have and how many miles?
M54 148,000 miles
It normally doesn't cause smoke on start-up. Usually leaking fuel injectors or blow by from piston rings cause that. Or coolant entering the combustion chamber from leaking head gasket. On accell its possible. But it sounds like it is something els
How the fuck did you put the small hose back wtf its ive been trying for 4 hours I just dont have enough space to put it back when the hose is connected
