how much wobble is normal on an n55 harmonic damper?
When I bough the car, pre-sale inspection flagged a wobbly harmonic damper. Another mechanic post-sales says some amount of wobble is normal on these cars. The forums seem to support the idea that some wobble is normal. This is counter-intuitive to me because I always thought there shouldn't be any wobble. I intend to keep the car for a long time so I want to fix problems early before they become bigger problems.
1) Are people just saying wobble acceptable because it won't cause damage unless it gets too bad?
2) do brand new BMWs have the wobble? To me that would be the answer to whether it is "normal" or not
3) If some amount of wobble is normal, how do you decide when it's bad enough to replace? Video links to acceptable wobble would be appreciated.
The HD is a $900CAD part. I don't want to spend the money needlessly. That said, I'm paranoid about the engine eating the drive belt since that apparently can happen. I'm at 95k km and am replacing OFHG (leaking) followed by a cleanup and then the belt, all the pulleys, and the tensioner.
Can anyone provide any advice?
