    As I was observing the application of the RTV silicone I was actually thinking “that is one of the neatest jobs I’ve ever seen when it comes to RTV silicone”
    And then you explained exactly that, I wish more would understand why it’s important to not put too much silicone.
    Well done buddy and keep going! You are doing a great job!
    It’s a true pleasure to watch your videos.

      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.😀

      @@nazeer3495 If everything is measured properly, good quality parts are used it’s really easy. The only tricky part in your rebuild is going to be the cranckshaft…hopefully it’s not developed micro cracks on the spun bearing side, and can be saved.

      When I rebuilt the bottom end of my X3 N57, I used Kolbenschmidt bearings with great results, but I had to wait a considerable time to get them. King is a good alternative.

    That plastic pipe on the side of the head @9:51 is prone to cracking at the seems or leaking from the gasket. Always worth changing when the inlet manifold is off.

    • @W15Garage
      @W15Garage  3 месяца назад

      @@Fabio_T26 thanks for watching! it is recommended to install them empty, when lifters are filled with oil before installation, they can cause valve clearance issues and may prevent the valves from closing properly, potentially leading to starting difficulties or misfires, after installation the lifters will automatically fill with oil as the engine runs and builds pressure.

In all of your video you never prime engine before First start After rebuild...why you crank It "dry"? Assembly lube It Is not sufficient for bearings After all of those steps of cranking...

    • @W15Garage
      @W15Garage  3 месяца назад

      It’s not always on camera, but I always crank the engine 3-5 times with the injectors disconnected after every timing chain job or engine rebuild to build up oil pressure. While assembly lube is beneficial, it does not replace oil pressure. The timing chain tensioners, lifters, bottom end, and the entire engine depend on sufficient oil pressure.

      @@justysone100 Hi, it’s performing spot-on. The oil pressure is good, and the power delivery is strong. I’ve clocked about 2,800-3,000 miles in total, and now I’m keeping it as a spare engine.
