Default Engine chatter on cold start up

Started my car this morning and heard some chatter from the engine, only at start up for about a minute. Never heard it this loud before and this morning was probably the coldest morning its been so far this fall. I'm thinking its time to change my chain tensioner. Any ideas?

My first thought is lifter tick. But diagnosing it is the easy part. How you get rid of it on the other hand... well that's a toughie

I would assume the lifters on your car are like any other 5 series and would go away when warmed and usually only appear if the car has been sitting for an extended period. Lifter tick is a very distinctive sound, so try youtube ing it.

Is the tick metallic sounding. It could be your exhaust mounts. I thought my car was ready to go because the exhaust was banging against something around the cats.

Of course it's a good idea to determine what is actually causing the noise


Some do have constant lifter noise, my car has the classic cold start tick. I haven't attempted to address it yet, but a few the things that others have tried with varying degrees of success:
  • check oil level
  • change oil/brand/weight
  • dump MMO or the like in crankcase ~100 miles prior to oil change
  • check oil pressure
  • check oil pump for loose bolts (common on m60)
  • change the offending lifter/s if isolated, or change all lifters

Or, just live with it. Mine seems to be getting a bit more prominent however, and it's embarrassing firing the ride up and having it sound like that every day though
