No M54 love?
Looking for an E39 belly pan , passenger front inner fender liner …
A bit of a bump, but, I have to replace the CCV on my 528 with an M52TU engine. As I see there's a big difference in the M52 and M52TU intake manifolds So I guess there's no way around it but to disconnect the intake manifold. So two questions:
1. Can I get the manifold out of the way without disconnecting the fuel rail, much like in the first guide?
2. While I'm doing the CCV, what other things should I replace besides the CCV? My best guess is that my manifold gaskets are done for after 155k miles, at least I doubt anybody replaced them midterm. What else could do with replacing? Any hoses? What can I replace on a budget, or is it best to not cheapskate around this or I'll be demolishing this again?
3. Is it as hard as it looks? I'm guessing on a scale 1-10, 1 is replacing a bulb, 10 is an engine rebuild, this looks like a 6.

Anybody? I've scouted around a bit, and as far as I can tell, you can reach the CCV if you remove the throttle body, but I wasn't able to pull it out because the hose that leads to the vanos cover was in the way. Any tips here? or is there just no way but to get it out the old fashioned way?
Time for me to change the CCV.
Live the e39..!!
The fuel rail can just sit out of the way on the engine. You should change the coolant hoses near the back of the manifold. They are the weakest link in the cooling IMO. Manifold gaskets are prolly the least of your probs so just check them first.
Its a piece of cake, I swapped in my m50 manifold in a few hours.
What kind of warning signs does the ccv give you when its going or gone bad?
have a small oil leak. Hard to diagnose if if its either the CCV or Oil filter housing Gasket (OFHG) because the leak is between the two on my E39. The leak starts between CCV and OFHG and reaches the oil pan but its not the oil pan. I did the CCV test with oil cap no noise or major air pull when you put a plastic bag on it. Its my e39 2003 with 130K.
Great diy. I just finished replacing the seperator on my 98 328i without removing the intake. I got it to exit the front. Thank you for contributing.

One suggestion, do not use the knockoff ccv valves! For the most part they are completely worthless and will cause you to replace it over and over until you buy a oem one.
hi james im going to do mine too. does the ccv come out easily
- - - Updated - - -
also are there only two hoses one at front and one at bottom of the pcv to remove?
What is this insanity lol......
I remember changing pcv valves on other cars, it took less than a minute!
But I really appreciate the detailed DYI, will need it.
Does anyone know a way to test the valve before removing it?
I got this sound and I'm wondering if it's the valve or a bearing

Very similar to this, only it's V8 and mine is V6

That sounds like an idler pulley, alternator, PS, AC noise. I'd suggest remove the serpentine belt and start the car to see if the noise persists or is gone. If gone with the car off try to turn each pulley to find the offending one. That is my initial thought.

You're probably right. I removed the CCV valve completely and the noise is still there

Oh and yeah, on M52 it's pretty easy to remove, no need to remove the manifold.
I mean it's not super easy, bit it's not as bad as I thought. The hardest part is to wiggle the valve out of there.
But there are only 3 bolts holding it in place. See pictures for details.

The valve plugs directly into the manifold connector when it's aligned with the screw holes.
Then there is a hose that goes to the intake valve that needs to be disconnected and another hose that goes to the dipstick.
So first unscrew the 3 bolts and pull on the valve gently, it will disconnect from the manifold.
Then remove the two remaining hoses from each side and wiggle it out from under.
A bit frustrating but if you're patient shouldn't take more than 30-60 minutes.
ive never heard a CCV sound anything like that. sounds very much like a rotating metal part.
