@@erikaszekely3315 thanks! Really appreciate it!

Hi, changing the cover will only stop the valve cover oil leak. High oil consumption, on the other hand, can be caused by many factors. The turbo can cause high oil consumption, valve stem seals can cause it, and in the worst case, worn-out piston rings

@@W15Garage Turbo is replaced with no effect but valve stem seals are good idea. Thanks ! 😎

Thanks for watching! Appreciate it

@@realmusicreallife thanks for watching! 100% correct, always something new to learn.

I enjoy mechanics, but I find no enjoyment in part replacements.

@@pyrox9944 you don’t put more tension since it’s not a longer tensioner. Original from bmw, same as the faulty one you would remove.

Thanks! Appreciate it😀

Thanks for watching!!😃

@@arnoldfarkas9268 Thanks for watching!! 100% correct, neglected cars

No, as it is now- chains can be removed and replaced

Thanks

@@eveniton Thanks for watching!

@@aminekaddache9767 everything will be checked. Thanks for watching

@@W15Garage oh thank you , i really learning lot from your videos

@@aminekaddache9767 thanks for watching!

Thanks

@@rulebraking This video was a demonstration only. If timing chain rattling is present, specially on cold start for a few seconds, it’s worth a try. Thanks for watching.

Thanks! You're absolutely right. If the rockers fail easily, the valves don't get damaged. There are other possible outcomes as well, such as bent camshafts, broken carriers, or valve damage, but this is the most common outcome. I have another failed chain, and I'm curious to see what the damage will be.

We r waiting..

@@matthewwalters7126 thanks for watching! Appreciate it!!

@@W15Garage your welcome looking forward to the next video

@@AMSR_VIDZ appreciate it thanks!

Thanks for watching! Correct!

Thanks! Appreciate your comment!

Thanks for watching, appreciate it! Good luck with your project! Nothing compares to the feeling when the car starts after a rebuild.😃 Let me know how it goes

@@duartegomes9455 thanks. King bearings among experts is a well known brand, they have a wide range of racing bearings as well.

Thanks for watching! Years ago, I found a BMW factory engine assembly video and saw a robot applying RTV silicone on the timing cover. I was amazed, and ever since, I’ve been trying to imitate that.😀

@@adamholmes-ii1qx it’s not unusual to have different heads 24-27 is ok. It shouldn’t be that tight only 70nm. Is your timing chain still the original? Maybe it was over tightened previously.

Iv not done chain befor . it’s a 3 series there’s not a lot ov room but im gona have another go tomorrow

There’s no evidence to say it’s bin done befor I bought it on 90 k it’s on 145k it just makes a noise on start up for few seconds

Thanks for replying

@@adamholmes-ii1qx just make sure socket sits properly on the tensioner, use a longer ratchet, should come out no problem.

@@Si-te7gz thanks appreciate it!

Thanks

Thanks!

Thanks for watching! This is a very delicate topic. Unfortunately, no one can predict the condition of a timing chain with certainty. I had an F25 with 178,000 miles (284,000 km) when I replaced the original timing chain as a precaution. It wasn’t stretched at all and had the same length as the new chain. However, I’ve also dealt with timing chain failure at only 94,000 miles. You can see the video on my channel. My advice would be, if you’re planning to keep the car for a longer period, change the timing chain for peace of mind. The F30 is a great car, and it would be a shame to drive it with constant worry over the timing chain.

@@aleksandarsavanovic4746 I think it has to do with the locking tool. But it is very simple, and it’s only one good position, otherwise the car won’t start. Pistons 1-4 needs to be at TDS, camshafIts locking tool fitted when the correct timing is set with the tensioners released. Descriptions tend to make it look harder but it is simple as that.

@@W15Garage Thank you for your answer, i have another question if you can please answer it. So... i have n47d20A engine in my bmw e90, and the engine is heavily damaged from piston to valve collision, now i only have option to buy n47d20A engine from x1, the fui assures me it will fit instead of my engine, and he told me only difference is in oil filter housing on engine which he gave to me, on further inspection the block look exactly the same as on my A engine, he also told me that f10 n47d20C would not fit because despite same engine code N47D20C f10 and e90 have different engine blocks. So what do you think about that swap and the mentioned differences in these engines?

N47D20A (177 hp) engines and N47D20C (184 hp) engines are not interchangeable. The block, cooling system, etc., are different, so it can’t be done. However, for models like the F10, E90 (after 2010), F30, and F20, it’s an easier job and can be done. You only need to swap the wiring harness, (injectors depending on horsepower), engine mounts, and oil pan, but the block fits. I’ve personally done many similar projects. The N47D20C has its own variants depending on horsepower. For example, the internals are more robust on a 120d 320d 520d (184 hp) than a 118d 116d (also some 116d f20 have 1.6 engine but that’s a different story ) but you can still swap them. Additionally, the 184 hp version has the cooling bolt for the bi-turbo version. Hope this makes sense.

@@W15Garage I will send you the link in your email from the forum post that i made so you can see the block and new engine

@@JonkKeithe cold start 3 second rattling could be timing chain/tensioner related, if aftermarket chain kit was used unfortunately they can wear out in 40-50.000miles

@@W15Garage thank you! Yes I think after market chain kit was used… So probably I should replace current tensioner with original and see?

There is also rattling noise driving up to 70-80km/h then it disappears. Once warm up it’s much better

@@JonkKei timing chain noise usually is not speed related, it’s RPM dependent. You can try instaling a new tensioner. In my opinion the 80km/h noise mentioned is coming from a different source.

@@W15Garage thank you. So the initial rattling is very clear on cold start and it seems it continues when accelerating up to 80km/hr while driving.

@@Kevinbjursell Thanks! No, just remove the tensioner, and refit the new one

@@W15Garage Thank you for answer! Is the tensioner placed the same position on F11 N47?

@@Kevinbjursell yes, just above the dpf. It’s easy to locate it, but be careful-only do it when engine is cold, otherwise risk of burning.

@@user-hu3jp3if6d Hi, thanks for watching. If i remember correctly 10Nm. If you Google it there is a picture for the N57 bolt sequence, that’s what I’ve used. Unfortunately in most cases the cover bends out of shape, I tried everything before I’ve decided to replace it. Still holding on good.

@@roningelertIf I remember correctly some similar fault code was present on the red mini from the video, camshaft cranckshaft correlation... B37C15A doesn’t have Vanos system being a diesel car.

@@W15Garage looks like I’m going to Bev changing the timing chains! Cam cover off first to check for slack?

@@roningelert yes, only the top one will be visible at that point, but usually top one is getting stretched

@@W15Garage Thanks for the confirmation

@@matthewwalters7126 thanks for watching, appreciate it.

@@W15Garage your welcome I enjoy your videos and watching you work on BMWs I can relate to your videos as I own an f20 with an N47 engine myself👍so watching you is good reference for me when I have to work on mine

Yes, it’s a well known fault, plastic doesn’t handle heat well, manufacturers tend to prefer cheaper solutions rather than longer lasting solutions

Thanks for watching. I would only recommend replacing it if there's a rattling sound at cold start that stops after a few seconds. Regular oil change intervals are crucial for a long-lasting engine and timing chain life. Don’t follow BMW's recommended high-mileage intervals; I personally change the oil every 6,000 to 7,000 miles at most in my N57 30d X3

@@W15Garage thanks for the reply. I’ve only had the car for 1 years and have done 8k miles in it so far, oil is being changed next week. But back to the main point, change the tensioner as soon as there is a rattle sound on cold start. Do you have any videos or anything so I know what to listen out for?
