That's the locking pin inside of the vanos unit... I'd replace it. These should be tight and play free. Any play can result in engine lag or vanos codes.
I am so impressed by your knowledge, skills, and dedication. Watching all these F10 videos has been an awe inspiring treat. Thank you so much. Very educational and unique. Eagerly looking forward to the final video(s) where you bring it all back together and bring it back to life. Good luck. Good work. And I hope you are feeling better.
I have the same exact f10 N55, which is amazing for oil leaks. I definitely need cleaning underneath my f10 looks just about the same as yours. i love the car, i truly enjoy your series keep it up bro
Yea for sure the 2 most common oil leaks are from the valve cover gasket and the oil filter housing and cooler. I'd recommend checking those out if you have oil leaks they are very common. And thanks for the love I really do appreciate it!
@ShawnzeyRacing oil fliter housing is fine but i suspect the gaskest cover it leaks and makes lil smoke in the engine bay and you can smell it when the car gets hot i need a fix for that for sure
I had the same thing on my previous F10. My valve cover gasket had a leak and the leak would drip on the exhaust manifold and id get an oil smell inside the cab of the car!
40:17 It will jump like that because the spring inside the VANOS variator is not strong enough to hold the valve springs below the camshaft. Normally you have oil inside, not air and oil is not compressible.
Thanks so much man! I have a lot of fun making these videos and it's even better when you guys enjoy them! This is my second N55 and I definitely agree with you lol.
He indeed had this kind of problem recently. If you look at his third last video (so part 2 of the Maserati), the "Looking inside a 187k mile Ferrari engine", starting at 31:40, he encounters a somewhat the same problem, a clunking noise from one of the actuators. I know it's a completely different engine, but if you keep watching for a bit, you'll see that he fixed it with another used actuator. So I think you did right buying a new one, with the engine in the current state it is still a quick swap. Just make sure it is an OE actuator, aftermarket parts and BMW's don't go together nicely.
You know that was my exact thought. But a bunch of other comments told me it was bad... So I ordered another one just to be safe. So I'll put it on but I'm glad someone else had this thought and not just me.
