What’s The Difference Between A Rebuild And An Overhaul?

A rebuild involves replacing key worn components, while an overhaul is more extensive—typically a full teardown and reconditioning of every internal engine part. We help you choose based on condition, mileage, and cost.

What Causes Cylinder Scoring?

Cylinder scoring is often caused by oil starvation, overheating, or foreign debris entering the combustion chamber. It can result in compression loss, poor performance, and long-term engine damage if not repaired.
