How Do I Know If My Engine Needs An Overhaul?

An engine overhaul may be necessary if you notice signs like excessive oil consumption, significant power loss, or unusual knocking sounds. Overhauls are often required for older engines showing advanced wear or for those that haven’t received consistent maintenance. A thorough inspection by our trained technicians can determine if an overhaul will improve performance and prevent future breakdowns.

Can I Drive With Engine Knock?

While it may be possible to drive with an engine knock, it is not advisable to do so. Engine knock can be caused by problems with engine compression or issues in the fuel system, which may worsen over time if left unaddressed. To avoid further damage and potential breakdowns, it’s best to have the engine inspected and repaired as soon as possible.
