MGA/MGB oiling question

[Glenn Mapes <gmapes@ball.com>]

Hi All

I have two friends that are racing MGs in vintage events - one is an MGA 
with a 3 main engine and the other is an MGB with a 5 main engine.  Both are 
having problems with getting enough oil the #2 and #3 rod bearings.  Does 
anyone know of a solution?  Would cross drilling the mains help?  What 
exactly is cross drilling and how is it done?

Thanks to all
