CCV for N52 2.5 engine 04/2006

[Reamesy]

I am looking for parts to change my CCV.

My car is 04/2006 2.5 N52 engine.

Looking at the Parts catalog on BMW site part number 11617559530 looks like one in one out. My part is more a y shape as seen on some websites. I went to BMW and they quoted me £181 for the full kit.

Part numbers
1 Oil separator (11617531423)
2 Vent hose (11617559530) part in question?
3 Vent pipe (11157522931)
4 Return pipe (11157567801)



My hose No.2 looks like the smallest hose in this picture. Any help will be appreciated. If you have done this yourself any links to the correct parts will be helpful.

OK, probably not exactly helping, but your hose in the photo looks as though it is totally plastic?
If so, and it's in good condition, could you not flush it through and re-use it?

 

[Reamesy]

That is not my actual hose. It is just an example of what it looks like. I am intending on changing them all as they become brittle due to heat. Given the work to remove it, I only want to do it once.

Thanks for your suggestion though.

Fair enough. Well I've looked through Realoem and ended up in the same place as you, sorry.

I’ve done a google search using the part number 11617559530. The images shown would point to mine.

Ive managed to find a Febi Bilstein Kit for £88.27 which works out £100.67 with delivery and free returns within 200 days if its not correct.

I have also ordered from BMW the Throttle body seal. (2 Pre-formed seal (13547522361) £9.50 all in so not worth buying third party as they were £6.16 from AutoDoc.

I will photo and document as I do the job. Be interesting to see the state of the intake and valves. Apparently the fuel injection is done above the valves and not direct into the cylinders so in effect washes over the valves cleaning as it goes. This was done to reduce coking. We will see.

Just a note. I am doing this to prevent failure of the CCV system. If it goes it can lead to all sorts of other blown seals or leaks due to heat causing the breather pipes to crack.

Interesting stuff, Reamesy. I'd done my own research on this and your part numbers tally with those I'd found for the 3.0l N52. Nothing surprising about that obviously, but thought worth noting for anyone else interested and reading this thread.

Would be great if you could share your experiences as I'm tossing up giving this a go myself or just letting the garage do it

 

[Reamesy]

I certainly will. The part numbers have been confirmed correct by BMW today.

I’m doing it myself as I want to make sure it’s done properly with nothing broken and all seals replaced where necessary.

I’m very particular and it’s the labour charges that would be expensive.

My reasoning too... plus the feeling of satisfaction you get

ok so finally got round to doing this today. Pretty straight forward. The only thing that caused me an issue was the cable assembly on the bottom side of the manifold. There are two torx screws that would no budge as they were rounded off. So I managed to manipulate the manifold so I could replace everything with it loose in situ.

You can see from the photos. One thing to note I had a lot of oil residue inside the manifold. The breather pipes were gummed up so hopefully caught it in time. No other leaks as all gaskets done now

I replaced the 6 manifold o rings and the green throttle body o ring which was not bad but 14 years old. The 6 manifold o rings were rock hard and flat.

Nice one and top marks for not only updating the thread but for including photos too

I've become a master of shifting rounded screws, bolts, etc over the years but I'll never master the despair of finding them in the first place :lol:

 

[Reamesy]

Lol. Just thought I can waste two hours just to completely remove it or just get it done. Cleaned up as much as I could. Total time was 2 hours in 1 degree as do not have the cover of a garage
