Thanks bro ! It was best explanation and all in detail. It did help who guy never changed oil. I wish you made video when you assemble and give us more information any electronic because lots connector are looks like same , when you open first time you don't pay much attention that you could forgot after week when get put together. Any way thanks

[@Ian-ij4of]

That was a good explanation and video on that job. I think im going to remove mine and have a look at the valves on cylinder 5. For some reaon when I started my car it threw the rocker and the follower clean off. I found them both lying in the cylinder head, bought new parts from BMW but after fitting it back together I can lift the rocker off the valve.3mm clearance, so I might have a sticking or bent inlet valve on cylinder 5. The lifter is solid but of course you cant get it fully out without removing the inlet camshaft. Looks clean anyway, i managed to get it half out.

just the video i was looking for thanx George my man !

Haha good idea😬

great video mate!! top job!

Thanks as always mate!

Just started this today after work bro.. managed to get to the point where the manifold is semi off. Wish me luck from Chicago

[@GeorgeAusters]

Good luck man!

[@Antonio-pq4fb]

I am planning on getting a E91 Touring with the N52 engine soon and really enjoying your videos to learn more about what kind of things I may have to do as preventative maintenance.

[@jonowen6612]

Beautiful video!

Thanks mate!

Thanks bro I did it with out removing the intake manifold

[@Coffinofagirl]

Did what? the video was about the intake manifold😂

[@nevrcm3261]

you forget to mention disconnecting the oil separator return pipe before fully removing the intake. It connects from the oil separator to the oil pan

[@othmanelahrach1247]

and that is the hardest part of this entire procedure.

[@nevrcm3261]

@@othmanelahrach1247 truly a major pain to disconnect

very helpful... thankyou

[@GeorgeAusters]

Glad it was helpful!

[@Himoutdoors]

Hi George, thanks for going through this job so clearly. I was a bit apprehensive, but now feel I can tackle this. I have a feeling my starter motor is on the way out, so need to do this job to access before I’m stranded. By the way, I’d like one of those little electric wrenches, that looks like a real timesaver! Cheers mate!

[@GeorgeAusters]

The ratchet should be linked in the description and check out my starter motor replacement video for that too👍🏻

[@Himoutdoors]

@@GeorgeAusters thanks. I couldn’t see the link, perhaps it expired. I will certainly check your start motor video. Anything else worth doing whilst you’re in there? Knock sensor?

[@GeorgeAusters]

@Himoutdoors Here is the link: Sealey Cordless Ratchet Kit: amzn.to/3bgAsKn I’ve never seen a knock sensor fail so no need really

[@Himoutdoors]

@@GeorgeAusters thanks, I’ve had a knock sensor code, could it be something else? Vanos? It’s not all the time just occasionally I get the ‘judders’ when accelerating. Fuel is fresh and from a good source, so should be high enough octane.

[@colin-hanlon]

I’m starting to do this now on a 3.0 N52 Z4 Coupe. Got the throttle body off, but there’s a cable going into where the throttle body attaches that looks like it needs to come off, but I can’t shift it. Not enough room.

[@bystander1489]

How did you get bottom ccv pipe with yellow clip on jeez I'm having big problems getting it on

[@bmerz9143]

Nice job

[@GeorgeAusters]

Thanks man

[@leiflillandt1488]

I happen to still have two e39 528i -96 and 528iT -00. I got the same problem with the engines of both. At -30°C the motors stalled... Then I had oil all over the engine bay... Then we opened the engine and some cylinders where full of oil... After cleaning and putting back all parts the engine fired up as usual. The breather pipes and the whole system froze at low temperatures, unless you made some preparations. 1) Cover up the grille. 2) When coming home after a less than 15 km drive. Let the motor idle for some minutes till everything in the engine bay is warm. Then you may be have no water in these systems. Some other brands have/had electric heated pipes. I didn't have a 230 v engine heater either, but in the x3 I have.

[@dhillonranaa]

It's same happened to my car it was -40 and I bet searched on it and every body saying ccv , I was stuck home anyways and open it found lots issued I could never notice , changed oil filter housing gasket, changed DISA, changed whole ccv pipes, now working on wire harness . It was more fun then my own job as machinist.

[@cyberairwolf]

just needing to access the inner rear bolt on the oil filter housing and may have rounded the bolt. soo need to hammer in my e10 socket. would it be sufficient enough to just remove the bolts from intake manifold to the engine and skip out the cables/and other bottom bolts? just need to move intake manifold to the side by a couple of inches. soo can access the oil housing bolt. will re-visit the intake manifold gaskets in the near future when parts are ordered.. what do you think? reckon just do the bolts and skip on disconnecting wirings and bottom or surrounding bolts? would appreciate your opinion/advise :)

[@arjunsandhu2843]

For some reason I just cannot take off the wire under the throttle body, what exactly is the technique to it?

[@jslade60]

Seems like you could rock that manifold back out-of-the-way enough to get to it to take it out without having to go through all of that!

[@motitaib8357]

[@honorablewiz7447]

why do some of these manifolds come with y hose and some with the elbow hose?

[@mattc6897]

Great vid. One question… The hidden connections, shown after removal… Is it easy to work out where they connect to when reinstalling or best to label? Thanks.

[@GeorgeAusters]

Was easy enough for me but best to label if you’re unsure

[@flyers30mvp]

Hey man I’ve been trying to install the intake manifold back on but the ccv hose at the bottom won’t clip on. Do you suggest putting the hose on first, then connecting it to the ccv?

[@GeorgeAusters]

I found it doesn’t click, more just a push on

[@zeeshanhanif3663]

Hi George, Did you replace your aluminium bolts for the intake manifold and the other bolts for the throttle body etc? Can you get away with using the old ones?

[@GeorgeAusters]

Pretty sure they’re all steel bolts

[@sysy8047]

You can use your old bolts but be careful not to over tight. Ideally you should use new bolts

[@theVOICE0f1]

How to re install and connector hoses?????

[@ginja485]

Do u have a junction box diagram, can’t find the n52 anywhere?

[@nathanjeffrey4722]

Thanks for the video George 👍 Question regarding the 4 electrical lines, how did you reach them before removing the manifold? I can’t reach them!

[@theequalizer3330]

From the front of the car lift the manifold and have both arms reaching round the back, like your bear hugging it, you might need a tiny flat head use both hands to wiggle and pick them out, the job is a pig, just because there is no space to move about, George made it look easier than it is, this job is not for the faint hearted, good look putting it all back together.

[@seanDB1989]

Out of interest, did you use a genuine breather hose or genuine BMW? Mine also broke, but now I’m wondering if to replace the hose (genuine/aftermarket) or replace the entire CCV including the return pipe…. What do you reckon?

[@GeorgeAusters]

I’d recommend BMW or FEBI and do the whole lot

[@seanDB1989]

@@GeorgeAusters thanks George! Brilliant video by the way! Wouldn’t have dared tackle this job without it!

[@paulfeatherstone7095]

Hello nice job just wondering is the breather pipe the same for the e88 plastic rocker cover. Thanks

[@GeorgeAusters]

Not 100% mate, I know there are 2 different kits so not sure which pipes are interchangeable. Best to check Realoem for part numbers👍🏻

When you start your car at the end it’s a bit lumpy mine does this also but only on startup like yours and sorts itself out within 5 seconds. Is this normal or is there something causing it?

Did you manage to resolve the clink from the Diff area? I’ve got the same problem and it’s driving me mad.!!!!! Any help appreciated :-)

[@GeorgeAusters]

Not yet mate. Thinking of getting the diff refurbished next year👍🏻

[@stevo8412]

It’s been like this for approx 10k miles, clicks are more often and aggressive. I’m pretty convinced it’s the diff, I’m thinking of just biting the bullet and getting a used diff. What do you think?

Is it worth to remove intake manifold just to replace its gasket? Or it’s not a good idea

[@GeorgeAusters]

Worth doing all the other jobs at the same time

[@aDmaNN266]

@@GeorgeAusters I bought 630i with oil housing dripping a little bit, I ordered intake manifold gaskets as well, but found out that I don't need to take off manifold to replace gaskets for housing. everything else works perfect, so I am not sure if I should risk breaking something by taking off manifold, I don't want to break pcv hose as well, and If something fails there, then I can save my gaskets if I ever need to remove that manifold.

Okay I see my car came up with code 2AA9. It is a 2006 BMW 330xi. Which sounded like it’s the smaller disa valve. From a video I watched it looked like it was right by that or on that intake valve.

I was stuck too bro , when I was changing coolant housing filter , that little bolt bottom of corner ,not much space for drill or any any thing , almost have up then just drill hole bet smaller than L key then hammer it and put krazy clue then try slowly and it works .
