R&L Engines: Engine Building Fueled by Lifelong Passion

June 26, 2025

On this episode of Rottler Featured Series join us at R&L Engines in Dover, New Hampshire.

R&L Engines is a 6,000 square foot state of the art engine rebuilding and machining facility that works on everything from vintage engines to high performance auto and marine motors.

Owner Leo Crossetier started R&L back in 1981 and later invested in his line-up of Rottler equipment because he got too busy and could no longer stand in front of a machine for hours a day. These days Leo and team have an assortment of specialized machining and fixtures, including the Rottler F69A Multi-purpose CNC, H85AX automatic hone, and SG9MTS seat & guide machine, that allow R&L to do high performance engine blueprinting that produces results far superior than the original manufacturers.

Leo’s team told us what they like the most about their Rottlers is that the machinery makes even the most difficult and time-consuming jobs accurate, repeatable and easy.

“Rottler machines do exactly what they should every time,” Leo said.

For our part here at Rottler, we’re happy to help the team at R&L do what they love! Check out the video!
