How Do I Know If My Truck Needs an Engine Overhaul?

Common signs include increased oil consumption, white or blue exhaust smoke, reduced power, and poor fuel efficiency. A failed compression test or low oil pressure may also indicate the need for a rebuild or full overhaul.

What’s the Difference Between a Rebuild and a Conversion?

A rebuild restores your existing engine by replacing worn components. A conversion (or repower) involves swapping your engine for a different make or model, often to meet performance or emissions goals.
