2.4. ENGINES

Engines in 2CVs are ultra-reliable air-cooled flat twins with 375, 425 or 602cc capacity.
Burton Car Company recommends the 602cc engine. This is the most suitable and is found in the 2CV6, Dyane6, Ami, Mehari or Acadiane. This engine is strong and has adequate power for a Burton. Parts are available everywhere. Even in ten years it will not be a problem to buy a new engine, for example.

An alternative is a Citroën-Visa engine or a 2CV engine with a big bore kit. This has a 652cc capacity and 38 hp. These engines are completely rebuilt with new original parts and have a full one year warranty. Burton Car Company also delivers a big bore kit that you can mount yourself.

The 2CV engine is not known to leak lots of oil. In case you find an oil-leak, this is usually due to an old oil-filler tube or a dried out gasket. This happens especially with engines that have been standing still for quite some time. A faulty oil filler tube causes a rise in the internal air pressure in the engine which causes the seals to leak.
An engine that sweats a little is no reason to worry.

Be aware that the air cool housing of a Dyane engine does not readily fit in a Burton due to the sideways-connected air filter. The air cool housing is best and easily replaced by the one from a 2CV. The alternative is, to remove the air filter tube and close the hole.
