What is a roller motor? I don't understand what it refers to. I never really paid attention to what was under the hood beyond locating oil dip stick and where to add window wash fluid. I am making an effort to learn now.
A roller motor refers to an engine from the factory that came with a roller cam instead of a flat tappet cam. Ford switched to roller cams in the mid '85 - '86.
When people say "roller motor" they're referring to an engine with roller tappets or lifters. Google "roller lifter" and you'll find info and pictures that will explain it.
Thanks Thanks. I am not going to ask about the difference in cam styles (yet). I will research those. I am enjoying learning about the mechanical side of cars.
