Engine timingFix: Moderate, basic tools

What usually causes it

  1. Low, dirty or wrong oil, because the timing adjuster runs on engine oil
  2. A stuck or dirty oil control valve, the small part that sends oil to the timing adjuster
  3. A worn or stretched timing chain
  4. A worn timing adjuster, also called a cam phaser

Check this first

Check the oil level with the dipstick. Low or very old oil is a common cause, and an oil change sometimes clears it.

What to watch for

  • Rough idle, stalling or weak power
  • A rattle from the front of the engine, most often right after a cold start
  • The oil warning light coming on
