I just replaced the timing chain on my 380sl, and the cam marks aligned perfectly with the 0 mark on the vibration damper. However, when I was rotating the chain manually to reinstall the rockers, before installing a new tensioner, I noticed that the chain would ocassionally jump on the passenger side, and now the cam marks and vibration damper are off by app. 18 degrees, which I think correponds to 1 tooth.
Can anyone tell me what's causing the new chain to jump like this, and how to correct it?
Thanks a lot.
