Hola desde España soy jonathan y le doy mil gracias por los excelentes vídeos orientativos yo también tengo un bmw e32 735il gris y la verdad no encontraba videos donde explicaran almenos las cosas básicas de mantenimiento de una forma pausada paso a paso y la verdad es que estaba TOTALMENTE PERDIDO CON MI BMW 735IL gracias a la manera que tienes de explicarlo pausadamente me a SIDO de gran ayuda muchas gracias de corazón ❤ por su pasión y dedicación y compartir sus conocimiento explicativos un abrazo compañero ( jonathan sebares de reinosa cantabria en España) 😊
Cactuar, many, many thanks for this video. I changed out my factory, 34 yr old injectors yesterday to the newer Bosch 4 ports, though I did use BMW o-rings at the head and rail, they seemed chunkier. I had this video on the laptop while I worked through the process. I bought a few back up EV-1 clips, and a few injector clips to be safe. The old injectors looked so bad, I can't believe the car was running, well even. It now sings, and it's a little smoother everywhere, and "seems" to pull a little hard in the 3-4.5k rev range; confirmation bias. : )
Thanks again for the time and effort it takes to put these videos together. I'm headed off the car meet today, so all the kids can look at my car like it's from Pleistocene era and ask about it.
Hi J Mtn, fantastic outcome! I'm happy that my video was helpful in some way when you changed your injectors. Your M30 engine must perform like a champ now. :)
Thank you so much!
Many thanks for your video, helped me a lot when doing the same to my car! Please do some more
Great I'm glad my videos are helpful :) I am trying to produce more videos as time (and money!) allows. The next video should be about steering components, possibly suspension too.
@@ClassicBMWFanInQuebec sounds good! Another one on suspension components would be awesome
As a fresh owner of 730i manual, would like to thank you for your visual documentation, it helps and will help a lot later on, cheers!
Thank you for the kind words, I am glad my videos help you!
Perfect thank you, just the video i needed :)
I'm glad to share this info, and happy it helped you!
great series will be doing this soon to my sons 535i very helpful as always
Glad to help vr!
Beautiful, classy car. I love the colour and those wheels look great on the E32! We have the same mentality when it comes to maintenance, - take care of the mechanicals first, then the cosmetics, and always use OEM and factory-style parts! Keep up the good work.
Thanks! It is a great color. The wheels were OE on the E38 750.
These cars need to be treated with more care than a typical car, preventative maintenance is key, using quality parts. It looks like you are following the same philosophy!
Thanks for this video! I resolved a hot start issue on my 535i by replacing the injectors. Mine was a little different, it has an EML. But I never would have had the confidence to try without this video.
Not sure if its something you would do, but I haven't been able to find any content on making sure that the AFM is correctly adjusted.
It's always cool to hear that my videos helped someone! Glad you were able to replace the injectors on your 535 and that it fixed your issue.
I believe the barn-door style AFM isn't adjustable? But I could be wrong... I don't know enough on the subject to make a video. But it's a good idea for the future.
@@ClassicBMWFanInQuebec I can tell mine has been fiddled with by a previous owner because it has been opened. There are videos like this (ruclips.net/video/yQukm7lNux4/видео.html) explaining how to do it. But the only way to know if you've adjusted correctly seems to be by measuring emissions. Not sure how I would do this at home.
Do you know the name or part number of the connecter at 6:35 in your video, on my car there are just 3 bare wires plugged into this connecter and I would like to buy a refit a proper connector.
Хороший ролик,благодарю)))
Great job as always! My 735iL is now starting to sway badly in the rear. I have polyurethane trailing arm bushings on the way, hope to have installed soon for summer! Keep up the top notch work!
Hi bmp130, thanks for watching! About the trailing arms, there is a spread sheet that a bimmerforum member built for the E34 chassis cars and it lists all the parts to replace in order to restore or improve the handling. Our E32's share many of the same parts. In this spread sheet it is highly recommended to *not* install poly bushing in the rear trailing arms. Instead it is better to use the OE part. The spread sheet can be found here, I hope it helps you! www.bimmerforums.com/forum/showthread.php?2443445-Suspension-Overhaul-Excel-Sheets
@@ClassicBMWFanInQuebec That’s unfortunate haha, wish I had read that sooner. I will probably install them for the interim and order some oem ones. Thanks for the info!
What injectors are theese? From m52b28? Nice video I'm also restoring m30b35, waiting for more!
They are Bosch 62417 injectors. They are for the E30 318i, E34 535i and E32 735i/IL. Basically the Motronic 1.3 cars.
@@ClassicBMWFanInQuebec So why they differ from your old ones if you say new ones are also from 735i?
@@mikoaj8033 My injectors were Lucas branded. These new Bosch ones are an improved design, known as Design III. They cost just a bit more than refurbishing my old ones.
Great video, I got a question, what is the part number of the new injectors? Cus Bosch one's are too expensive!
The injectors I used are Bosch 62417. They aren't that expensive (47 CAD each on Rockauto), but I agree when you order six it does add up. Still it's a lot more affordable than buying the injectors from BMW. They are 340 CAD, each! (part 13641706176)
I would recommend saving for a bit and buying six new Bosch injectors when you are ready. Don't use cheap eBay injectors in your M30.
Ohhhh man! Why so late? I did the same injector replacement this winter...
That's too bad! I've been wanting to do the injectors for a long time but kept prioritizing other stuff instead (fuel pump, spark plug wires etc). Hopefully it helps others who have yet to change their injectors! :)
so the idle issue was the injectors?
I am not so sure. The idle is better, and the hunting is less pronounced. But it's still there... The engine is smoother however, so that's an improvement. It doesn't shake as much.
@@ClassicBMWFanInQuebec have the same goddamn problem , changed almost everything except injectors
@@fatihkara9638 I know how you feel, it's a persisting problem that is difficult to fix. Many people contacted me saying they had the same problem on their 735. Hopefully one of us find the fix, then we can share the knowledge.
@@ClassicBMWFanInQuebec have you changed the O2 sensor ? i think that can cause that smell and rough idle
