You can hear a small change in sound ,,i sounds "deeper" than before, thinking a couple oil changes ( like 3, every 2000 miles) will do it ,after the 3 oil changes just do it every 5k miles to be safe.
I know these cars and engines quite well and I personally would put 5W40 into the engine and change it after 1 year or 15k kms. I use Ravenol NDT for my tuned N57 and I'm really happy with it. Other than that, these engines are notorious for oil pressure and timing chain problems, which doesn't automatically mean that your car is affected too. I personally changed my timing chain and the oil pump to make the engine live longer, just to be on the safe side. I've put in a upgrade oil pump from DiTuPa from germany. Besides that, you probably need to clean the air intake in a warm bath with cloth wash powder, drain cleaner and a water pump which pumps the cleaning solution through the air intake manifold. I did all this and it cleaned my plastic intake manifold spotless clean from the carbon buildup.
George, I think you have Ista+, but is it usable for that old car? Try to figure out if you can use Ista+ to decide if the transmission chains has been tensioned. Maybe the one of the tensioner should be changed? Then I think the noise can be changed/lowered with some certain oil. I also think viscosity has an impact on the noise level. But oil changes do not repair broken things... 😉
Looks like a leaky rad. Just replaced mine about 4 weeks ago. The rad was deformed at the bottom but leaked 1/2 way up. Replaced std coolant with Comma Xstream G64. Done a 400mile trip Saturday mostly motorway doing 50-80 mostly, got 64mpg. BMW 320d E91 N47D20O0 2009 M Sport pack, K&N, Remapped.
I think the squeek is coming from your alternator mate, I had the same issue with mine with a slight squeek and then eventually it gave up and I had to replace it
Change the upper tensioner for peace of mind. You can do it in five minutes. Also I think the car got a little less rattley after the oil change but did you leave it overnight so the oil rests fully in the pan?
so I have a N47 and just done my oil and filter but I also did the chain tensioner with engine in situ and its completely eliminated the chain noise. Not saying it will work for everyone but will say the tensioner in it wasnt doing the job, was much weaker than the upgraded tensioner. You have to remove the sway bar to get a breaker in there and 27mm long reach socket but wasnt the worst job ever.
small change in engine sound, most likely due to new oil. Why don't you pour some oil on the new filter before installing it. this will allow faster new oil circulation on first startup after oil/filter change. I have 7yr old BMW F11 LCI B47D20 (60k miles) and an 10yr old R56 Mini N18B16A engine, 50k miles (did a precautionary timing chain change 30k miles back on Mini, also best to use 5W40 A3/B3 or B4 oil with mini). New Mini engine is v.good as it is the update , as is the B47D20, no timing chain change on BMW, runs great. Also, did a timing change on an older Mini with N14B16A, chain had stretched about 4mm, with 60k miles and 7 yr old car. Had a fantastic 2009 Audi V6 3.0TDI CDYA for 9 yrs, drove 100k trouble free miles all around europe, often with full car. New Audi V6 3.0 engines are not as good. Live in Sweden, so we have high engine wear cold starts, so i do use engine heaters. Good vid, thanks.
Have you thought of doing an oil change with engine flush, removing some carbon buildups inside. I keep thinking about doing that myself because my car has over 400k km and see if that would make the engine run smoother and quieter cuz its an m47(tractor) 😀
@@Coops95I have heard the exact same thing from a guy that has had a shop for more than 15 years, and worked with cars for 40 years. You have to start with flushes when the car is new! There are a lit of tiny channels and if a big "particulate" get stuck in such a channel or nozzle, you are in big trouble to say the least. Normal oils contain (small amounts of) detergents (and dispergents) and the best way is to change the oil after a "few" miles.
I say a bit better, quiet - I'm acute with my hearing. Also, I think my Torque Convertor is going bad - what symptoms should I look out for? Any guidance is appreciated!
@@wasy35 not really on downshifts but lets say your in 6th gear around 2000rpm once you let go of the throttle and are slowing down without braking, the rpms will just be bouncing up and down by a few hundred rpms. Well at least thats the most common faulty torque converter symptom.
@@piovo1 I'll try that today - to see if the RPM bounce and I've noticed that they do but I'll double check - the bouncing of the RPM is what clued me in to the fact that the Torque converter may be faulting. Again, thanks for the guidance.
Slightly quieter on start up. The sweeking noise from the belt is very off putting so its making it difficult to be 100% sure. My son has the same car and engine. These generation of N47 engines are particulary noisey.
I have a 320d 2017 160k all its ever had is a screen wash pump my 335 f30 has had timing chain rod bearings prop shaft and guilbo. Thats done 100k served both same time 10k miles look the 335 is fast smooth quiet but as much as i dont want to admit it tye 320 is more reliable 335 avarge 39mpg the 320 56 mpg and when it come to servicing ie brakes the 320 is half the price same for oil changes as the 335 takes like 7l so cheaper to buy 10 the 320 5l. The 335 is a betyer car all over but if its about money and reliabilty the 320d won by miles also its a manual no flyhweel rattle the 335d has had to gearbox services at 500 a time @@ianjenkins4641
You have to be daft to think an oil change will help stop chain rattling 😂😂😂. If the is stretched then nothing won't help only chain change will help! 😂
I can hear a difference on startup. Your videos are invaluable to me as i own the same engine so TY.
Great to hear!

Great to meet you at the gym yesterday George 👍🏻
Great to meet you too mate!
Definitely sounds much better and I think it will improve when you do more frequent oil changes compared to the previous owner.
Definitely sounds smoother 👍

How much was timing chain change?
Love these types of videos mate
More to come!
Before and after sounded similar to me. That generation of BMW diesels were fairly noisy, I couldn't say for sure whether that was timing chain noise.
Great video thanks for sharing

..try replacing the upper chain tensioner, there is a longer one, so that will quieten it down a bit..
I’d get the tensioner changed for how cheap they are, it fixed all my chain noises upon startup.
Interesting!
I've heard this too... Next service 👍
Same, quietened my F11 right down on start up.
Sounds 100% percent better.

I could definitely hear the difference. Much smoother after oil change, unless it was because the engine was warmer.

It’s not, I have a video coming soon where I fix it👍🏻

May do the upper tensioner if I feel like it!

which ramps are those? im looking to get a set for working on my 318d but worried it will be too low to drive up onto a lot of ramps. cheers
Brother! How many liters of oil does the BMW N47D20C diesel engine take?
5-5.5

Change the external tensioner… I did on my n47 and it was much much quite

Been told to avoid engine flush if it's not done regularly as could cause more problems ie oil leaks.

I don’t think this engine is very dirty inside if I’m honest judging how relatively clean the oil was
Timing chain is about to go. Cold start sounds loud then when heated is up sounds better. Mine broke on my N57 330D E90
Previous owner replaced it
i think it sounds slightly better you know
Rockin' that footwear George! What are they? Slippers or Sliders?
Hahaha rockin the sliders
I say a bit better, quiet - I'm acute with my hearing. Also, I think my Torque Convertor is going bad - what symptoms should I look out for? Any guidance is appreciated!
What year is the car? If it’s a E series the ZF6s usually you get a whine or upon deceleration the rpm needle bounces up and down.
It's a 2004 745i - I don't hear a whine but the RPM do bounce upon downshifts - but RPM also bounce when I start the car. and not in gear just idling

It does sound quiter
Gave you a 'like' cos I felt sorry for you for having one of these.
Nice one, so satisfying... glad you didn't use KFC oil! 😂
😂
You know if it’s chain when you turn car off you should hear it slap 👋
Slight difference but there's still a rattle,. time to change the chain I think
Definitely better
I see you make a mistake: you must first the filter oil and after you can put the tap
Slightly quieter on start up. The sweeking noise from the belt is very off putting so its making it difficult to be 100% sure. My son has the same car and engine. These generation of N47 engines are particulary noisey.

Of course if the chain is the issue.. but the issue could be dirty oil not filling the tensioner enough
@@GeorgeAusters why not just check it then if it's need changing or not?
