Just finished the rebuild and the engine is perfect. Must have watched your videos over 50 times in total. Thanks again for this amazing video series 🙌
Brawo Bimmer.! Ja już 1000 km zrobiłem po remoncie silnika. Składałem swój silnik w tym samym czasie co ty. Twoje filmy z remontu N43 bardzo mi pomogły. Wielkie dzięki 💪💪
been waiting for this one for a long while, bravo, i've got misfire on cylinder 1 and 3, injectors have been tested, coil packs are fine, new spark plugs, new vanos, made a mistake, shorted the high pressure fuel pump on the positive terminal, today i found the vaccum pump leaking and oil in the vaccum side and i haven't driven anywhere, it was lumpy on idle.
Congratulations on a successful rebuild - it looks like the remaining problems can all be solved with a few new parts. I'm just doing an N46 bottom end swap after buying an E87 with engine noise - it was a rod bearing which then destroyed the crankshaft journal. Your videos are very helpful!
Yes! Great timing. Just putting the intake back on! Nice one on getting it running - nit quite there yet but i know it will not beat you 🙂 thanks again for the series. ❤
Good morning. I have been following you for a long time. and I want to thank you for your practical videos which helped me a lot. I have a problem with the electric oil level before starting I check the level (maximum). and after driving a few thirty kms I cut off the engine (minimum light +1L) I leave the car. after a few hours I start check (maximum) and it repeats. I have no apparent leaks and no smoke too. thank you very much 💪💪 N46B20 318I 2007 .
Finally some good videos about a n43. Love to watch yours. Can you also get deeper into the oilpressure issue? Had the same error code but dont realy know what could have caused it
I greet you once again, I need your help, please, how do you do it on the first start with the spark plugs, everything installed and put in the automatic or remove the spark plugs and drive until the oil filling is done. Thanks for the answer
Thanks for sharing your experience, waiting for the next update about 30C1, ¿have you tried to replace the oil back-valve (it is located in the bottom part of the oil filter body) like bimmerprofs said ?
Hi there, what a great video! The "low oil pressure" code is exactly what I've been frequently seeing. Would you happen to know when is the new video going to be released? I can't wait to see what you have done to rectify this issue. I have already changed the oil pressure sensor as well as the oil pressure regulator, there is no foreign particles on my oil filter, but at this stage I start to worry that it might be my oil pump? The car has only 153000 km on it so it's not that much...
I had to replace the oil pressure valve which solved the issue. But in your case, given that the oil pressure regulator valve is in good working order, you might have the dreaded clogged oil pickup (broken plastic chain rail guides) or damaged oil pump. I would investigate immediately.
Well its all back in and fired up and totally gutting is theres a knocking sound. Its had a new crank, new bearings, new rings, engine balanced, new tappets… did añl the tightening to spec so really cant get my head around it. Im using mineral running in oil. Sounds bottom end but different to original knock it had with the knackered bearing. Wondering what ti do now. 😢
Well i think ive sorted it. Was either a noisy tappet, tensioner or an issue with intake. I fixed an error with direct injection intake or something - controls the flap, swapped tensioner for another new one and maybe oil filled up… dunno but its running ok now!!! 😅 thank **** for that. Thought all that work and cash gone to waste. Mot next hurdle. Shojld be good if emmisions ok. 👍
I have this massive shudder and shake when turning off engine you can feel the shake from inside the car so far replaced throttle body engne mounts and gearbox mount what else can it be its f10 520d 2 litre n47 engine
Hi, I have a BMW 318i 2012 N43 engine. I bought it with a low oil pressure warning light on the dash. 1. I changed the oil pressure sensor but still lights on. 2. I changed the oil pressure regulator valve still the problem there. 3. I removed the sump and there were a lot of timing chain pieces stuck in the pickup tube and in the sump. I cleaned the pickup tube and sump. Put a new timing chain. But still low oil pressure light is on. I flushed the engine and changed engine oil twice in one week but the problem is still there. Checked oil filter housing and but everything seems fine. I don't know what to do next. It's just the oil pump remaining which can cause the low oil pressure. Note: the low oil pressure warning pops up after running the car at high speed for 10 to 15 minutes and when stop at a traffic light it just pops up. The car drives fine. No engine noise and when I remove the engine oil cap oil comes out with pressure. I am waiting for your reply. Because if not then I am going to change the oil pump which is pain in the a**s.
Well, good job so far, so keep zen:) Did you check for debris in the oil cooler? Maybe its clogged with the debris? You remo ed the oil filter housing and cleaned all of the channels and check valve inside? The next thing could obviously be the oil pump. Pieces can damage or stuck the variable volume mechanism. Maybe it is broken, ive seen that before:instagram.com/p/Cz9tWFrKzj_/?igsh=MXY2YnRtcHcwNDZhag==
Hi! Whats the correct compression for this engine? I have 7bar/100 psi on every cylinder. Is it enough it to work properly or is it too low? What is the compression when the engine is new? Thanks if you can answer! 🙂
@@MeisterSchaft13 minimum is 10 bar. No spec for new engine. My estimation is 12 bar max. Try with a few drops of oil in each cylinder. Also check if the vanos adaptatios are within spec. Jumped chain may cause low compression.
@@BimmerZen The problem i have is the compression tester is a cheap chinese tester. So i dont trust it. How to clear the vanos adaptations, is there a free tool for it or a cheap tester that can do it? Is it a must to clear the adaptations when the cylinder head has been off? The car idles pretty ok and no adaptations has been cleared.
Now i got a dumb question, i got a n42b20 105kw, i would like to invest some money in it do you have any advice what to upgrade or where to even buy example better valve springs etc. Seems like there is nothing better then stock on the internet. Thanks in advance, great video btw.
Hey! I love your videos and currently rebuilding my second car's engine, could you please advise me? The piston ring gaps is in a weird situation, where 1 ring range 0,20...0,30 with result of 0,27 not going in 2 ring range 0,30 ... 0,45 with 0,48 going in, and 0,50 not going in with older ones the engine was working with 1 ring being around 0,34 and 2 ring 0,55. is 0,03 from maximum on a second ring bad?
As I describe in my N43 bottom end rebuild video; the second ring is primarily an oil scraper ring and is not that critical for the compression, so I think you should be fine with slightly out of spec second ring.
"Replace chain rail guide if engine's more than 10 years old" -- my N42 is on 22 years old and I'm stressing!! First thing I want to do is add a digital oil pressure sensor so I can be sure oil starvation never happens.
I would advise you to replace the plastic chain rail guide and chain tensioner. Oil pumps on the N42/N46 are pretty solid, oil starvation only happens when the pickup gets blocked with broken pieces of guide.
It’s sound advise to change the plastic guides , mine failed when taken for MOT test when engine revved higher than I dare. Roughly £50 for parts , £30 for timing chain kit. And for me. Labour free

Great series. Anticipating the video on the low pressure It’s been 2 months!! 😂 All the best 🫡
Best BMW channel ever! Thank you for sharing your knowledge.
Well done sir and thank you for the meticulous documentation of your process helping us others doing the same thing 🙏

Excellent presentation. Being a motor vehicle repair technician ( all be it from the 1970s to the 1990s ) I can relate to you

Yes, I have a video comming up shortly on this exact topic:)
Is there any reinforced aftermarket rail guide to prevent this from happening again in the future?
@@antoniomartingarcia6229 not that i'm aware of.

One problem the N42 doesn't have at least is injector hell hahahaha

You have that video yet? I think i have some injector Problems even tho they are less then 1,5 years old..(replaced all of them last year)
There is still an issue that I am trying to sort out, but I have more or less all of the footage, I just need to put a coherent video together:D

Sorry, I have no experience in tunning these engines. My best advice is to just get the six cylinder car, but I'm sure you've heard that before:D
The missfire can be produced by the o2 sensors, it just happends to me 😅

first fix injector problems, they can lead to cat errors.
N43 is junk,N46 its better,320k km and only timing and valve stem seals changed,and some o-rings
And vakvetronic motor 😂😂
