BMW 320D M47N2 Timing chain replacement

[@Blackdavid2011]

For owners that are here about this engine. this is the last cast iron engine comming out of factory.. which probably will last forever. I used 5W40 from 250k km TWO makes of oil, Mobil 1 for a while, then a switch to Shell Pure Plus. oil change 15k km. If you drive decently in revs early in the morning and let it run for 1 minute or 2 before you drive in the morning... it will oulast any other engine!!!!!! As a plus I used (and still using of course!) 2 Stroke oil (FB category for non-DPF model), and this formula looks after HP pump and injectors, big time! 250 ml/50 litres of diesel. ....Have I told you that 2 injectors "failed" with a loud BANG in one early moning while driving? Tested them all with return flow; 2 of them were pissing a lot of fuel (2 of them) ...send them to specialist Bosch testing and repair center. Got tested on the bench ------ got a phone call from them ----- my injectors passed all the bench tests. they were the original one factory fitted, at that moment lasted 480k km!!!! NO SIGN OF FAILURE except that BANG in the mornig... but the engine carried running... even after that. And I put all this on the use of 2 Stroke Oil. It is NOT a kind of placebo; is definiitely not for me!! This is a real fact. Off course I told them to rebuild those injectors (cost 300 pounds for 2) because they were the worst on my poor little return flow test.. I hope this helps other to consider this workable prevention. A, before a leave.. the intake manifold it was clogged up with gunk, deposits at 250k km when I bought the car. !!. After extensively using 2 Stroke oil formula, NO DEPOSITS on intake manifold! Checked twice; nothing to clean! Have I told you it has the genuine EGR and swirl flaps at almost HALF MILLION KILOMETERS? Yes it does! ?..how much it cost an EGR? A lot.. I wish you all well and I might inspire a few with my experience; real, genuine, no BS.

[@istvanbognar5453]

Hello! What are you mean "loud BANG"? Why do you use 5w-40? 5w-30 is fitted for this engine C3 Castrol Edge. What kind/brand of 2Stroke oil have you using? Thanks!

[@MrFryfish]

​@@istvanbognar5453 well lets agree over something - no injectors live forever! 😉 Then there is and won't be a better description of what I said... a loud bang is similar with a big hammer like a kilogram heavy hitting a large 0.5 to 1cm thick piece of metal on the pavement; it was that kind of noise; and only once ...being hit.. or similar noise when same hammer hit a empty metal barrel, once, again. You got the idea. Why? Probably because the car most of the time has been driven moderatly on acceleration, not often with harsh acceleration and brake of speed.. so the engine being slowly accelerated everything else has kind of time to happen around the injectors including A RETURN FLOW process, which i noticed last time when I fitted the "new" actually well rebuild x2 injectors that I put back on the engine. Prior to that I did another return flow on all injectors - 2 off ebay, 2 as old as the ones sent for rebuild to Bosch representative! Well, now according to the last test when 2 where massively leaking back fuel and sent for rebuild, the ones that were in use atthe present moment under test where leaking kind of 3 more (almost the same) and one a quite a bit less.. (so this is a second test after I first touched the injectors with the incident of bang..). So now, after replacing the really old ones with the refurbished (and tested again) for return flow - THREE WERE LEAKING LESS (I mean normal!) than one (this one off ebay). So the injectors were registered in DDE as well after every change for better injectors.. I hope this is now much clearer.

[@MrFryfish]

​@@istvanbognar5453 So, I think, this happend to me specifically because the car was driven moderately a lot of time, and trying to put everything back together, in my mind, one "strange" thing I noticed on the engine, when I was testing for return flow , was that on the hose that is connected to the return to send back the fuel (return of diesel by itself flowing, I imagined..) ACTUALLY there is a bit of pressure, I MEAN REAL FLOW of fuel COMMING TOWARDS THE INJECTORS from the back! So now I am thinking that the "flow back" expression is real because of this flow I notice! so there at the injectors, there is a forward flow, from high pressure ramp, via switching part of the injectors.. but a pressure from some pump.. (high pressure pump returning fuel not needed for high pressure..?) that actually can fload the injectors from opposite direction, hence kind of detonation when 2 piston could get fuel and detonate at the same time.../ just to add an idea - the BANG was manifested with a sudden (brief) stop of the car, engine.. but then, fraction of a second later IT KEPT GOING, running. you see, when you do the return flow test, peoples blocked, or locked the return flow from from the injectors back to fuel tank. Me, I haven't blocked/locked that hose, wanted to watch and aknowledge everything. There is many, many more time return flow of the diesel, "back" (actually towards the return of the injectors!) than from the injectors themselves!!! So, I believe that is the case of return flow! the error code on Carly or ISTA+ is the same: internal ECU16 / internal control unit 16 / DDE control unit. Code: 4293 (clear as mud..)

[@MrFryfish]

@@istvanbognar5453 wrong. BMW is using Shell as their oil supplier for a little whle (couple of years) More specific, Shell pure plus technology. I am using that oil for about 150k miles. over 200k km. AND 5w30 was used for FIRTS 250k miles. Do not tell me that there is no wear out in ICE engine after 200k miles or 300k miles, equivalent to 400k km or 500k km...! Do you understand a bit how an engine work or you just ask? If you nevere repaired anything to the engine then let's not argue. 🙂😉

[@istvanbognar5453]

M47 engine need Castrol C3. Shell is a newer Engine need. Anyway why wrote Castrol sign on the Oil filling Cap? Just a decoration? Iam not thinking that...@@MrFryfish

I own a bmw 3 series with 490k km. Never ever missed a start! If I do a compression test at its age... and is still ok, what else would you recommend to replace on this ocassion - replacement of timing chain. Last question please, what make would you recommend for timing chain kit? And by the way 😊😊😊 YOU ARE A BRILLIANT TEACHER EXPLAINING THE PROCESS!!! HUGE THANK YOU.

[@MmetalbikesS]

I would recommend febi bilstein timing chain kit. It contains IWIS timing chains and guides, which is the manufacturer of the Original BMW timing chain kit, but way cheaper.

[@MrFixit-vw8kc]

Go for good brand timing chain and spares. This is a big job to save on cheap and unreliable parts. I used swag. 👍

[@MrFryfish]

@@MmetalbikesS i find out from other sources (bmw forums) that of course IWIS is the main supplier of bmw timing chain. but I do not think is the same with febi.. I like febi biltein: all suspenssion on my car is made by them. Standard I installed.. Now the BMW dealer was offering for 480 instead of 560 the whole kit! I means, 2 genuine sprockets.. everything they change when timing chain is done by them! Being an old engine probably dust is covering on their shelves.. being a REDUTABILE ENGINE is worse for sale parts.. BUT I am convince that the pollution is less because I am changing parts, fixing .. not keep buy cars, creating piles of rubbish.. and my car is driven very much between cities, less in the city itself!

[@woutervandermost6123]

Thank you for this very helpful video. I am planning to change my chains soon too on my 2006 BMW 320d with manual transmission. It has 410.000km and I suspect the chains have never been replaced. (There is no mention of it in the service booklet which seems to be complete for all maintenance and repairs). Some questions I hope you can help with: 1. Why did you loosen the 2 engine mounts? Is that needed to lower the subframe? 2. In a pro Haynes service instruction (which is way to superficial in my view) it says the transmission must be removed. I have not seen this in your video nor in any other instruction. I guess it’s not needed. 3. I am also struggling to find the proper way to lock the engine. I saw in another comment the pinhole is located close to the starter. Is it in the transmission housing? And I assume you rotate the crankshaft close to the TDC by visually checking (by placing a rod in cilinder 1?) and next try to insert the pin? To lock the pin in the hole the flywheel must be aligned very precisely. Seems quite difficult for just 1 person. Or is there a smart way to do this? Additional info on this locking is highly appreciated. 4. How did you torque the crankshaft pulley to the right torque (100Nm and 150 degrees). Did you use a special pulley blocking tool? 5. Did you clean the housing of the injectors, especially the surface where the copper ring meets the engine block, somehow before putting the injectors back? I read somewhere else that this is quite important to avoid leaks. I just don’t know how to do it and what tool to use. Thanks!

[@MrFixit-vw8kc]

Thanks for Your comment, I wish you patience while performing this job. It is not verry difficult, however time consuming. Do not rush on things, take time to do it all properly, to have the right timing and no oil leaks later on. 1- yes to lower subframe to remove oil pan 2-no need to remove transmission in this case. 3- yes the pin hole is next to starter on the engine block side, not the transmission. See the video where you initially set the camshafte in just about right position, the. Go underneath the car and see where you are on the flywheel. The flywheel has a plate on the side when you are just about right this plate size visually will match the check slot. See the video I have showed it. After you will remove oil pan, then you will be able visually see the right slot on the flywheel and while inserting locking pin you might need to turn the engine one or the other way . I prefere to do it this way, as then I am sure that I have locked engine in the TDC and the timing set later will be correct. Some mechanicks insert the locking pin by the feeling without visually checking. You will see the flywheel has a lot of slots and it is easy to miss the right one.

[@MrFixit-vw8kc]

4- to tight the wibration damper i locked the flywheel underneath the car with crawbar 😃, asked a friend to assist and hold it while I tighted the bolt down. 5-yes, this is verry important to have the injector holes spotless. I use long enough flat screwdriver, wrap a rag around the screwdriver insert it in the hole and turn the screwdriver. Rag will pick up all debries and dirt. Do it as many times necessary to have the holes clean.

You need to lock the tensioners to free the chains. When the chain is released then you can replace the chains, guides. If tensioner is not locked it is impossible to do the replacement. 🫡

[@sdfghfd3650]

Hi, did your idle speed changed after this replacement ? At what speed does your engine idle now ? I have a low idle issue on my 2002 320d (700rpm) which cause some vibrations and the red oil light to turn on when idling warm... Some people suggested that this might come from a loose / damaged timing chain since it is linked to the oil pump and camshaft. What do you think ? Great video, thank you !

[@MrFixit-vw8kc]

Hi, the idle speed did not changed before and after the chain replacement. It idles at around 850rpm. You need to avoid running engine on so low 700 rpm, this means at that speed oil pump is turning too slow to supply enough oil to lubricate the critical engine parts. Low oil pressure can cause serious engine damage. Rough or low idle can come from air leaks. This can be checked by performing smoke test. Also if there is an air leak, the fuel consumption will be grater than normal, and also the car can feel low power when accelerating hard. Check some basic things before replacing chain. Also before replacing chain, some decent workshops can measure by how much the chain have stretched and is it critical to replace or not. Hope it helps, good luck in dealing with the issue

[@sdfghfd3650]

Thank you for answering No power or consumption issue but there might be an air leak so I'll check that (high whistling sound when accelerating).

[@FrodoTEST]

Thank you for this excelent, step by step tutorial. I only have one comment to make: I did not get the part when you "reset" the timing because the chain is streched. I mean I understand that but how do you reset the timing when everything is locked?

[@MrFixit-vw8kc]

Thanks for Your comment. That is my bad that I did not showed this important part. To set the timing right You need to use same tool I checked the timing before I dissasambled everything. When you have replaced the chains, and the fly wheel is locked, release the cam shaft sprocket tightening bolts, but just release do not remove, afterwards place the timing tool over the camshafts and make sure the tool sits flash on both sides on both camshafts. Then you are good to tight the sprocket bolts 👍 hope I managed to explain well. Good luck in replacing the chains 🙏
