How much does it cost to fix a knocking engine?
I'm hearing a strange knocking sound coming from my engine. Unless someone is trying to escape from under the hood, I think I have a mechanical issue. What’s the cost of fixing a knocking engine?

Considering it’s the biggest, most expensive component of your vehicle, a malfunctioning engine is definitely cause for concern! Brace yourself, because fixing a knocking engine can cost up to $4,000.
Knocking sounds in your engine usually indicate a faulty engine rod. The distinctive "rod knock" is the sound of the crankshaft journal colliding with the bearing.
Dismantling, repairing, and reassembling an engine is tricky because of its complexity and the number of parts involved. The cost to repair rod knock ranges from $2,000 to $4,000. Engine repairs are costly, but engine replacements are even worse, so don't wait to see a mechanic!
