Injector removal & valve cover gasket replacement | BMW M47 / M57

Valve cover gasket replacement on BMW's legendary M47 diesel engine, with more than 500000km, on the e46 (Compact) chassis. Since this job requires removing the injectors, I also demonstrate how to remove them, clean the injector seats, and refresh them with new washers and seals. Of course, I inspect the timing chain for play and check the swirl flaps for the first time since last year's cleanup. ------------------------------------------------------------ Update: 8 months later ----------------------------------------------------------- Turns out I made a couple of big mistakes when reinstalling the valve cover. First, the valve cover bolts are supposed to be torqued to 9–10 Nm. I didn’t think it was that important and just went by feel, which resulted in the cover not sitting flat. Second, I applied RTV gasket on the areas with sharp changes in direction. The RTV eventually hardened, causing those areas not to seal properly. About eight months after doing the job, the valve cover started leaking badly. At first, I didn’t realize what was actually wrong and assumed the leak was from the bolts not being tight enough. I tried adding more torque to the bolt on the corner—and snapped it. Here’s a video of me fixing these mistakes:    • Redoing the valve cover gasket | BMW M47   ------------------------------------------------------------------ Timestamps --------------------------------------------------------------------- 0:00 Mileage 0:04 Intake air duct removal 0:25 Cabin air filter/tray removal 2:04 Injector harness removal 2:38 Intake manifold removal 4:48 Unplugging the MAP sensor 4:55 Intake manifold removal 6:06 Swirl flaps check 6:21 Injector numbering 7:07 Injector removal 12:23 Air filter removal 12:57 Valve cover removal 13:59 Top-end inspection 14:17 Injector seats cutting/cleaning 16:25 Dangerous but effective technique 16:55 Injector seats cutting/cleaning 17:07 Timing chain play inspection 17:35 Valve cover gasket replacement 19:01 RTV on sharp changes in direction 19:24 Installing valve cover 20:19 Torqued down to "trust-me-bro" Nm 21:05 Preparing the injectors 23:21 A touch of high temp copper grease 23:36 Installing injectors 26:11 Air filter/ducts back on 27:07 Intake manifold back on 27:49 Torqued down to "that-ain't-gown-owhere" lb/ft·rifle^2 28:02 Plugging in the MAP sensor 28:19 Injector harness back in place 28:28 Finishing intake manifold ducting 28:38 Plugging in the injector harness 28:58 Will it run? 30:40 Reinstalling cabin air filter 31:04 Conclusions
