You didn't explain why you had to rebuild it I once had a code for vanos inlet is that's what you doing or do you know what that is I did like the video it's just wish you explain why
I made separate video about that ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CPIDWd4cl28.html but it pretty much shows how you can compare the actual vanos position to the desired position
This one didn’t really have a rattle problem just sluggish (the lifters are definitely the loudest thing on the engine I was working on) but it wouldn’t be too much more work to do the anti rattle once you get to this point.
