  • Lifters. An engine uses a series of lifters in order to provide the necessary force to mechanically open and close its valves.
  • Exhaust Leaks.
  • Misadjusted Valves.
  • Damaged or Worn Spark Plugs.
  • Worn Accessory Drive Pulleys.
  • What causes an engine tick?

It’s also probably belts if your car squeals as it idles or warms up after starting.
