Used Rebuilt Engine 1990–2019

A rebuilt engine has been fully disassembled, measured, and assembled with new rings, bearings, gaskets, and seals. The block and crank are usually machined back to spec, and worn parts are replaced rather than reused. The result is an engine that starts fresh on wear. Gone compression across multiple cylinders, oil consumption over a quart per thousand miles, or rod knock are the signs it's time. Swapping a rebuilt unit is usually cheaper than machining a worn engine if you don't have a core to start with. Redline carries 12 rebuilt engines from 8 makes.
