For both parts and labor, fixing a knocking engine can cost $2,000-$3,000 on average. If the damage is worse, you may have to pay to replace extra parts as well. Don’t put off this repair because the damage will only get worse (and the expenses will rise).
The repair costs for a knocking engine rod will depend on a few factors:
  • How long the engine has been knocking
  • How serious the damage is
  • If the engine can be salvaged
  • If it is a high-performance engine
You may be experienced in car maintenance, but repairing a knocking engine is best left to the professionals.
