[Fot] Question on Accusump Install with External Oil Lines On a Spitfire

[Kas Kastner]

Don't be fooled by just enlarging the bores of the oil ways.  There is a 
bushing that intrudes into the main gallery in the 6 cylinder engines and it 
restricts the flow to the front of the engine.  THAT is why I did the piping 
to the cam bearing taped holes in the side of the block way back in the late 
60's.  It is the front of the engine that starves.
