Drove my 316 TI for 4 years with the same cold start rattle. I sold it without being fixed because i could not find the problem. Another interesting video! Thank you!
!!!!!!SOLVED!!!!!! Ive had this noise 3 times now and it goes away when i change my oil. the oil only lasts 2 years. it is normal for it to only last two years even if you only put a 1000 miles on it. it deteriorates even quicker when the car stands for long periods. for me it comes back every two years till i service it, if i use the car every day, or once a week. ive been on all forums and no one seems to realize it.
I have the same problem (video/sound on my chanel). I wrote a message in an e46 forum to get some help and sb. mentioned that it could be the check valve in the oil filter housing. I can't wait to see your solution ;) BR
Thanks for this video! I've had exactly the same issue on my N42 engine, a weird growling type rattle that lasts for around a second after not driving for several hours. Always thought it might be the sound the vanos makes dry until it gets oil pumped to it, hopefully we'll find out soon what it is because that noise is annoying and worrying lol
Watch his video after this he explains his noise was the check valve inside the oil filter housing, I've tried cleaning cleaning my check valve and it stopped the noise for a little while but now its returned. I'm wondering if I didn't clean it well enough or if there is another problem.
@@jordan_watts_ ive Opened the oil Filter after 1 day and it was half full of oil or are some hoses clogged that this oil in the housing cant get to the engine fast enough
Try check the smallest oil filter seal inside the housing that we replace with every oil change, if the seal is worn, the pressure in the system will become low since the oil leaks trough and end up in the oil pan
Hello BimmerZen, I am having the same issue with my N42 engine. I tried already replacing the chain + chain tensioner, inspected VANOS units, replaced oil pump and this is still rattling. My guess for now is to replace oil filter housing, but not sure if it's gonna help. I look forward to check out you coming videos on this topic. btw thanks for the content - it's helpful and interesting ;)
I had the same issues and replaced many parts... now it seems that the check valve in the oil filter housing is the culprit. I am making a video on that this week.
@@BimmerZen najprej preveri, ce mas dovolj dolg filter/vlozek ali probaj s kako drugo firmo filtra. Ena varianta je, da ti filter ne drzi ventila zaprtega in ti olje odtece nazaj v karter.
Good job. Did you have to use special tool or trick on putting the new one? You kinda lost there. I know you had to use both hands. Any tips or tricks on putting the new one? Steps? Thanks chief
Dear BimmerZen: Thanks for a very helpful video, especially the procedure for removing a VANOS unit in situ. However, while you demonstrated how to replace an exhaust VANOS unit, you never explained why you thought it would solve the startup rattle? I couldn't see why it would work so was not surprised that it didn't cure the problem. Surely the symptoms point to oil starvation? Oil drains away from the cylinder head when the car is left standing, and this causes a rattle in the valve gear, etc. This stops once oil pressure is restored (about 1-2 seconds after starting the engine). I have found that turning the engine over (but not starting it) solves the problem because the oil pump is mechanical. So, the solution has to lie with the oil filter or related parts? Something is allowing oil to drain from the cylinder head... Anyway, sorry for the long comment and thanks as always for your hard work in marking these videos!
I have read on the internet that exhaust VANOS units get worn out and can cause the rattle. If you take a look at my VANOS inspection videos, you can see that there are some wear marks, so I thought that maybe the oil drains from the exhaust VANOS unit, causing it to start depleted of oil. Another possibility is that the VANOS unit locking pin gets stuck due to wear.
So whats the solution now? İm so depressed with this Startup rattle. İve checked my Oil Filter it was half full the next day for years i thought it was the oil Filter housing. Which Oil you Guys use ? If we have minus Celsius i dont have this rattle which i have everyday in the morning. So i think if the oil is thicker the oilpump builds more pressure. İve tried 0W40 5W40. İve read about that this engine is similiar to the psa engines from Peugeot etc. These engine only can use 0W30 and 5W30 i will Change my oil to thst next time. My car began to rattle after i switched my original BMW battery to a exide one idk how its related
Hi chief, great awesome job. Will this concept theory be applied to N51/N52 engines? Same locking tool and procedure? I have to replace the bolt heads on the Exhaust Camshaft. please advise chief. Thx

I also have a nasty sound when starting the engine. It's from vanos. How to check the vanos before buying to make it in bad condition ?? I mean a used vanos.
About the valve cover gasket, apart for putting the silicone on the cylinder head I think you also should put some silicone between the valve cover itself and the gasket.
Hi can I ask you I have error code 2A61 and after replacing timing chain have problem with cold start and can be problem with timing on vanos I have angle intake 114.9 and exhaust 54.6 .i dont know where start solved this problem if check valvatronic shaft or sensor of vanos on intake or intake vanos or chain or any thing can you help me
When re installing the koged part or the vanos ( the one in contact with timing chain) does orientation matter? It looks like the impulse sender matters but the whole vanos assembly doesn't? Please explain. I need to know if it matters 😅
@@tahirzeeshan500 Orientation of the sprocket is not important. The important part that needs to be oriented correctly is the impulse sending gear. These are oriented correctly with the front locking tool with pins that engage with the holes on the impulse sending gears.
That black thing is the secondary air pump and the silver thing is the one-way valve. They are installed on most N42/N46 engines with EURO 4 emission standard. The secondary air pump is activated on cold startup for a minute or so and pumps extra air via one-way check valve in to the exhaust ports in the cylinder head. This way the catalytic converter heats up faster and the engine produces less emissions.
@@BimmerZen the issue that im having is that the exhaust camshaft is not really on the correct timing, the intake is, i need to correct it but i don't want to block the flywheel would that be possible?

Was the oil check valve at fault? Just bought one of these bmw which has low oil pressure for 5 seconds at startup, otherwise drives great!
Great video as always!

In my case great for startup rattle is new oil filter after about 5000km and always high oil level. Check it out.
Hi chief, great awesome job.
Will this concept theory be applied to N51/N52 engines? Same locking tool and procedure?

Tnkx for shearing but mine smokes too
Check my videos on valve stem seals for fixing oil consumption
Is it very hard to put the new Vanos in the chain using 2 hands? Or are there any special tricks?
I also have a nasty sound when starting the engine. It's from vanos. How to check the vanos before buying to make it in bad condition ?? I mean a used vanos.
I think I found the cause of my startup rattle. Here is the video: ruclips.net/video/N5h5GB9eiKo/видео.html
We're all waiting in great anticipation!
About the valve cover gasket, apart for putting the silicone on the cylinder head I think you also should put some silicone between the valve cover itself and the gasket.
It could be timing chain tensioners the N42 engines are famous for failing
Chain tensioner was already replaced with the latest version.
Hi can I ask you I have error code 2A61 and after replacing timing chain have problem with cold start and can be problem with timing on vanos I have angle intake 114.9 and exhaust 54.6 .i dont know where start solved this problem if check valvatronic shaft or sensor of vanos on intake or intake vanos or chain or any thing can you help me
Replaced exhaust vanos unit with brand new one and the rattle is completely gone
Catless headers but secondary airpump? Not by default i guess?
It's stock and it has cats on the headers.
When re installing the koged part or the vanos ( the one in contact with timing chain) does orientation matter? It looks like the impulse sender matters but the whole vanos assembly doesn't? Please explain. I need to know if it matters 😅
I plan to change my exhaust vanos unit with cheap febi bilstein from autodoc. Is it good? Original bmw is at 700 each in norway 😂
@@tahirzeeshan500 Orientation of the sprocket is not important. The important part that needs to be oriented correctly is the impulse sending gear. These are oriented correctly with the front locking tool with pins that engage with the holes on the impulse sending gears.
@@tahirzeeshan500 I haven't seen aftermarket VANOS units, but FEBI Bilstein should be an OK choice. I haven't had any issues with their parts so far.
@@BimmerZen ok. Thank you very much for answering. Im much more confident on doing this job and swaping valvestems now.👍
This is a great video thank you
Hello. Do you need to block the flywheel to replace the vanos ??
No, if you do the procedure as described in my video.
whats the black container next to windsceen wash and the thing ontop of the exhaust manfiold, my n46 318 doesnt have either of those?
That black thing is the secondary air pump and the silver thing is the one-way valve. They are installed on most N42/N46 engines with EURO 4 emission standard. The secondary air pump is activated on cold startup for a minute or so and pumps extra air via one-way check valve in to the exhaust ports in the cylinder head. This way the catalytic converter heats up faster and the engine produces less emissions.
@@BimmerZen ok i see, i don’t have any cats, so i’m assuming that’s why they’re missing
@@ethxnhxrst1575I too have the N46 318i. And it's not fitted with either as you described. Uk model
Is this the same as the n43?
No.
@@BimmerZen the issue that im having is that the exhaust camshaft is not really on the correct timing, the intake is, i need to correct it but i don't want to block the flywheel would that be possible?
Since he started making noise he started eating a lot of oil
Oil consumption is probably due to CCV or valve stem seals. Noise could be broken chain rail or valvetronic issue.
