Engine Number Finder

Engine Number

The easiest place to find the engine number is on the Lotus-Holbay alloy valve cover.


The engine number will also show up on the front mounted Holbay oil pump, if still equipped.  The photo below shows the location of that number.   In this view, the scavenger section of the pump has been removed for clarity.


The engine number may also show up on internal engine components.  

 This piston is from engine #382.  It was the #3 piston.

On the flywheel, from engine #141.
