Hey guys and welcome back to the SimpleCarGuy Channel. Today we are installing injectors on my BMW N55 engine with an early production date. The reason I mention this is because the process is different on newer engines and if you’d like to see what that process is like, check out my video on the BMW N20 injector replacement as it’s exactly the same. In this video, the injectors are already removed from the vehicle, so once again, if you need those steps, check out the N20 video in the description. Now, let’s go to the garage, get the injectors prepared, installed and at the same time hit that like button for the YouTube Algorithms.
Now we are going to replace the decoupling elements and the Teflon rings on my used injectors. These must be replaced or you will have issues in the future such as lose of compression or fuel blowby. The decoupling elements simply pop off with a flat head screwdriver and a new ones can pop back in once we do the seals and clean the area.
Next we remove the Teflon ring seal by carefully cutting it with a razor blade or a box cutter and peeling it off the injector. You don’t want to cut into the injector, so be careful here. With those out of the way, we can wipe the injector with a clean paper towel and pop the new decoupling elements in place. The round part of the element faces the nozzle of the injector. For the next steps you are supposed to use a few special tools, but I do it my own way. You can find the proper tools in the description if you’d rather use those.
This really does work well, you just have to find the correct diameter plastic pieces or cut them down to size.
I have a video on how to adjust the compensation on the injectors from a couple of years ago, so check that out if you need steps. With that, thanks for watching, I hope you found the video useful and I’ll see you in the next one!
