  A rattling noise from the chain when cold can lead to engine damage.
  Solution: Replace the chain and tensioners in a timely manner.

  If there is a drop in power, smoke, or oil consumption, the turbo should be checked.
  Solution: Use quality oil, and have the turbo revised or replaced if faulty.
