Oooooh. More work.

How hard is it to check the timing chain and oil pump chain? I'm not a mechanic, so I might even miss things as I check, since I don't know what I'm looking for.

Also, when checking the timing chain, is this a good time to try to get the timing perfect? My car is not as smooth at idle as it could be. I was once in a 1992 300d with 150k miles on it, and you'd never know the car had been started, it was THAT smooth.
