Every used engine we sell has been thoroughly inspected and tested by our diesel engineers before it leaves our workshop. Rebuilt engines are assembled using genuine parts and come with a warranty.
Stock changes regularly, so get in touch — we may have something coming through the workshop, or we can source a specific engine for you.
