Replace PCV-CCV valve BMW N62 V8 tailpipe smoke rough idle 540 545 550 640 645 650 735 740 745 750

This is common problem but easy fix in all BMW cars.
Similar procedures for all N62 engines in BMW e53 X5 e60 e61 e63 e64 e65 e66
Other 4 and 6 cylinders in 2002-2015 BMW should be the same.

You are so welcome!

Do you know what size are the screws on the engine cover? I want to put my cover back on but I lost the screws

[@jessepickar3297]

Can you tell us the part number or give us a link?

[@BadHabitz23]

What cold air intake is that? Also have links to the kits you bought?

[@DurianGarage]

This intake filter kit was customized just for the looks (K&N Cone filter, silicone hose, and fiberglass cover) . I think the factory intake set was good enough. :)

[@samking4179]

Isn't there a vacuum hose that connects to the cap of the one on the passenger side? Also, are they sold as a pair or just singles? Thanks!

[@Dineliasreparaciones]

Thats what I noticed on 2004

[@Dineliasreparaciones]

I would like to know if its needed because mine doesn’t have it but i took the hose and spliter from one at junkyard

[@anaugustbornroze2415]

Yea I’m trying to figure this out my self the new caps don’t come with the nippel they said bmw updated it and you don’t need the nipple anymore but you need to remove the house

[@neoshade6462]

Replacing mine in a few days im pretty sure its the cause of some squeaking and rough idle for me will update though.

[@joko.760]

If these are fine what else could be the cause of the rough idle and smoke exchaust

[@DurianGarage]

You may wanna check spark plugs and coils. If all is well, then have injectors cleaned.

[@anaugustbornroze2415]

If you properly replaced these and your 100 percent sure you don’t have vacuum leaks it will 100 percent be the valve stem seals

[@animalgift692]

How should the car stop smoking after replacing is it immediately or few days

[@DurianGarage]

If this diaphragm is the cause, smoke should stop within the next drive.

[@animalgift692]

If it still smoke what might be the cause because am driving 540i E60 V8.. the smoke is not continuous, when it idles for like 3mins when i drive it releases a white smoke then the smoke is gone again until i stop again on traffic then same problem all over again

[@DurianGarage]

Although your symptom sounds like accumulated oil puddle in intake plenum, which burns out during driving and causes smoke, but next step might be might me valve stem seal. Before going further, just be sure the ccv valve is correctly replaced and the plastic casing/cap is bone dry.

[@taylorsons4303]

They also have one in the back also its much bigger than the 2 in the front.

[@animalgift692]

Not in the 540i E60 v8

Just found it on Amazon, listed as CCV Pressure Regulating Valve

I can't find that cap with the male fit here in Arizona. They only sell the female.

[@SRG420]

you ever find out anything more? currently going thru the same issue. Tech on the phone was telling me that the original way was to connect the hoses to the caps. Apparently now BMW recommends not to connect those hoses. Thats why its made without the little barb

[@gaijinxrecords6683]

@@SRG420 well, I just put the caps they gave me on it so it has a whistle for a blow off technically. Ha. The reason that these aren't male anymore is because they changed the whole setup. I believe it was called pcv breather setup. So just throw the new caps on and be cool with or order the whole setup which I think still ends up doing the same thing

[@gaijinxrecords6683]

@@SRG420 I wanted to put breather filters on the ends or an oil catch can on both but it doesn't look likely. I have little car knowledge

[@Dineliasreparaciones]

Is the Vacum hose needed

[@DurianGarage]

There is no vacuum nipple nor vacuum hose connected to the cap prior to removal.

[@sama-ln2gp]

@@DurianGarage there is a nipple on your old ones. i can see it in the video. the new ones dont have nipples. maybe dont need the hose.

[@anaugustbornroze2415]

Yes I agree I need an explanation please help my old one both come with a nipple or tip to connect the hose I understand I don’t need it anymore but the. How do I properly replace or remove the vacuum hose
