Rebuilt or Repaired Engine Assemblies
Somerford Mini Ltd. offers an engine rebuilding and repair service, courtesy of its workshop facility. We
can carry out repairs or rebuilds on late-model engines, but the extent of rebuilding on an early engine
is governed by - and sometimes restricted by - parts availability. Please contact us to discuss your Mini
engine requirements - it would be helpful if you could supply us not only the details of what’s gone
wrong with your engine, but also the full engine number (if known) and type (capacity, high or low
compression, gearbox, breathing system, etc.). The more you can give us, the better we can help you.
