Fair comment, as its fair to say the original race engines produced by Norton leaked oil everywhere. This bike was built with mainly new parts supplied by Andy Molnar including the engine. Molnar engines are built to exact 1962 factory design but enhanced using modern production methods and materials.
Molnar engines have magnesium crankcases, timing covers & cam boxes as the original, cast from the Norton pattern work, CNC machined in house on state of the art 5 axis CNC machines, then re-dichromated for corrosion protection & authentic appearance. Sand cast aluminium cylinder barrel as original with spun cast iron liner. Precision sand cast cylinder heads from original pattern work are 5 axis CNC machined & ported, fitted with hard "Lead free" valve seats, "Colsibro" valve guides and stainless valves.
As you see there are no oil leaks after approximately 950 miles of use.
