Frequently asked questions

When should pistons be replaced in a diesel engine?

Pistons typically need replacement during a major engine overhaul, usually at 8,000-15,000 operating hours. Signs include excessive oil consumption, blue exhaust smoke, low compression readings, and piston slap noise during cold starts.

What's included in a piston kit vs a bare piston?

A piston kit typically includes the piston, piston rings, wrist pin, and snap rings. A bare piston is just the piston body. We recommend purchasing complete kits to ensure all components are matched and compatible.
