Hi. No, everything stays in place.

Easy and cheap except for the wet belt systems like in peugeot, citroen, ford

Belt doesn't come on all cars so how is that even relevant when it's a video about a bmw with a chain

£1000-£2000 depending on who does it.

£1000 if you use somewhere like X5 Engineering (the soecialists imo) other indipendents charge £1500 … dealer will be £2000+

I did ask my garage for my rwd n57 engine bmw just last week. 2500£ was their price as he said only parts are 1200-1300£. Main dealer- 4000£+

Its b

Hi. Every time when chaging pump, injector or even filter, fuel system should be primed using diagnostic equipment.

Many people miss this step out and some make it worse by removing the pipe from the fuel filter, so all the fuel runs out of the pump rather than disconnecting the fuel line from the high pressure pump line which has a one way valve, this at least keeps fuel in the pump - To bleed it's in ISTA Service Functions - Fuel Bleed If all the fuel has ran out of the pump, it must be primed or there's a chance of the roller bearing inside picking up on the cam and the pump will die in a matter of weeks, fills all your high pressure lines with swarf and contaminates the fuel tank via the return. Same thing if you put petrol in by mistake, got to get it towed, do not start the engine.

@@nemz7505 I don’t really understand your point? If your replacing the pump there will be no diesel in the new pump and also the fuel filter is better to be replaced with the new pump along with injectors and fuel rail. I got mine bled via software

No not nesessery. I just made it for better view

Yes, thats normal sound.

@@jonasjo202 thank you for your answer :)

Yes, but you need a friend to hold the crankshaft .

@@jonasjo202 yep, that's for sure. But I thin in your case it's also necessary to hold it. Or you just used the fixator?

Usualy i am useing fixator, but sometimes it goes quite easy...

Hi. Replaceing with original BMW spare parts, it can last 150-200 000km.

No

Hi. I do not remember how much KM, but you must bleed fuel system after filter change.

Hi. I beleave the sprocket is still tight on axel. Take a look on my other videos, you will understand. Did you use special tool to release pumps sprocket?

@@jonasjo202 Yes, but i didnt hear the "click" everyone talks about. I just started trying to pull it out and it got a little more out, but its still very tight...

Sometimes there is one more small very long bolt from the gearbox side.

I also misread the title... Thought it said n47 (the one i have), but it might be almost the same thing

I have changed them. My opinion poor oil chande, start stop system etc.

No, not necessary, just working from the top

and on f30 n57 ?? I can without removing the gearbox??

Hi. Not nesessery to remove gearbox.

Hi. Tool holds sprocket perfectly. Yes, you can remove pump, no Gearbox removal. Its quite easy job. Just before putting on take a look, sprocket has spline.

Thank you. What is the torque for sprocket bolt? Is it torqued up so gently?

@@maciejkociszewski3045 65NM, your wellcomme! Greetings from LT 😄

Its just for fun😅, everyting is ok. That motor is running till now.

Hi not necessary, but must lower down suspension. For xdrive also diff and other parts.

@@jonasjo202 thank you so much for the prompt response! will check on the pump asap!

apart from the swirl flaps failing

@Jules Anderson L'ignoranza ti fa parlare...fai qualche ricerca sulle caratteristiche delle autovetture prodotte da BMW e capirai da solo che hai detto una stupidata. Ti do un piccolo indizio...distribuzione del peso! Saluti dall'Italia

In such case, there's more than bad tensioner. There's should be something else broken too.

@@jonasjo202 it dosent jump as easily as in your video it takes about as much much effort as it would take to spin the engine, I can see/hear the timing chain jump a tooth on the crank gear when doing so. No issues turning the crank clockwise only does this when turning counter clockwise. I was hoping to just retime engine and put a new timing chain tensioner.

@@jonasjo202 this happend right after a valve cover replacement and new coil packs. The coil packs were bad and the engine ran terrible for about 30 seconds than it threw intake and cam correlation codes right away. Engine sounded perfectly fine with the old coil packs and before we took the valve cover off to take a better look. This is when I noticed the teeth jumping when turning counter clockwise. Highly feel like the engine in its current state is undamaged( piston valve contact) want to make sure it stays that way. This is on a n55

@@mustafay4427 hi. On these gasoline engines i had changed plastic guides and chains many times, because they get old and brokes down easy. Also they chain skips as well. So, take a better look and check timing. Good luck 🤞

@@jonasjo202 thanks for the reply the car has 200,000 kms but also running a much bigger turbo. Even with a new chain tensioner the guide is moving a lot. The intake cam is pretty hard to turn the exhaust cam is smooth. Can this be due to valvetronic? ruclips.net/user/shortsKvYA5yQ6KfY?feature=share ruclips.net/user/shorts77R97QNRFHM?feature=share

Replace it

Fuel pumps in tank pressure is controlled eletricaly by controller (there's no regulators). Pressure should be around 4bar.

Yes, all 3. Almost always I'm changing oil pump also.

@@jonasjo202 Nicely done! I watched guides with 2wd with gearbox removed. So for xdrive you removed cv axle and front differential, anything else?

@@Lamelldiff this way how i do: first remove valve cover, then hang engine on strong holder. Then take down gear box. After that put suspension down and take of rear diff, axels and oil pan. And then the rest. It is complicated job to do, takes few days.

@@jonasjo202 thank for explanation. Is it possible to replace two chains exluding oil pump? Like to split/open up chain lock/Snap? Iknow its best to do all at once but so much more to do. Thanks for answers.

Snapping chain method you can replace only top one, tensioner, one guide and top sprocket. I had done this once.

Hi. Never has happened to me. As I understand: when you unscrew e14 bolt, at the same time unscrews also tool? Maybe try to lubricate tool and bolt to reduce friction against them. Also the tool must be fully screwed in.

Yes, they both come loose Is it possible that with the N47 you first have to remove the bolt then insert the tool? I saw that on RUclips or is this absolutely not recommended

No, do not remove bolt alone. I believe something's wrong with the bolt's cap. Maybe it's surface damaged and grips together with tool. On other hand, if you have new bolt, replace it, and then try again. Lubricate, to reduce friction.

@@pronsbrook1792hello i have the same problem do you have any idea ?

​@@pronsbrook1792 did you find the issue

Hi. If chains hasn't never been changed or serviced until now, better save money for changing them. Sometimes delaying costs tvice.

You should be chaging the timing around 200000 km. Anything after that is a gift. The problem is not only the chains and tensioners etc but the crankshaft bearings. They are all gone by this time. I just did my own timing and had only 187000 km and the bearings are worn. If you dont change the bearings it wont last long. You have to pull the engine out of these vehicles and remove the crankshaft.

True, true 😂😭🤞

those chains arent so problematic like everybody says mine n47 has 320k km on the clock with second chain fitted at 225k km but it was not strechted at all. and my friend has a n47 with 260k km with original chain the key is besides frequent oil changes also to warm up the engine before driving. it cant be possible that timing belts last longer than timing chains

@@pavokx well I think it depends alot on how you use the car, if you use it alot for city driving with frequent engine on/off, then you will put a strain on the chain. That also goes for start/stop system... Doesn't matter for me anymore because I already changed 2 cars since then and now I have Cayenne 3.0TDI (no chain service done yet). Btw are you also from Slovenia, because of your name?

Hi. Yes, but sometimes goes without locking.

@@jonasjo202 thanks very much for the info

Hi. Probably needs to change. Well maintained engine doesn't make additional sounds whatever cold or hot. Good luck 🤞😃

Hi. Yes I did.

Hi. Did you find out something?

@@jonasjo202 not yet. Waiting for the pump removal tool to arrive. It's driving me insane to be unsure

@@rouankritzinger5010 did you find ? i changed my hpfp it’s not starting at all i will change common rail

@@packm2045 I had an airlock in the system and also a faulty earth line. Finally got it running

@@rouankritzinger5010 did you chnage injector fuel tank etc??

Hi. What engine you are working on?

@@jonasjo202 I'm working on my bmw x3 e83 with the N47d20a engine

Ok. You can try to open high pressure fuel pump and look for metal shavings. There is my video how it looks inside. It's possible to access pump on the car. ruclips.net/video/rRsRSqyKEs0/видео.html

Hi. Just lock the flywheel with pin near the starter. Or ask help to hold crankshaft. Good luck

@@jonasjo202 thank you
