Check the car first, avoid a spike: https://bit.ly/3CZfaNs Voucher 30% discount: fch30dis In this episode I started working on the E39 525d. Because there is a lot of work to do. Problem no. 1 is that 2 injectors are blocked in the cylinder head. I tried various ways to remove them but I couldn't. That is until I created a tool for this. A homemade injector extractor by hitting :) There is a kit to buy for extracting M57 & N47 injectors but I don't think it's necessarily worth it. In this video it is explained step by step how to remove a blocked injector at home. You need a long 29mm tubular with a hole, a 10-point secured fitting (i.e. with a hole in it) and the piece that threads into the injector. Otherwise, you look for a thicker rod/pipe, weld a nut, a stopper at the top and a weight. This is how you can remove the injector yourself. That's if you're lucky.. if not, you make a lever like the guys in the video :)) I also installed the new 3.0d 184hp injectors. BOSCH F00V C17 504 fuel washers. Ceramic grease resistant to 1200 degrees. Business: [email protected] Instagram: / morar.davian
