A center section with the filler tube

passage cut away

looks as if it leaves a couple openings to

be closed.

How is this done? Can't see any patches in

the engine

Robert,
I don't know!
I do know you can weld cast iron by preheating

it first, but I have

never

attempted it, although there is a chap I know

who might - I will ask

him.

Robert,
 I asked my welder mate and he said 'Cast iron is

not a metal that is

readily conducive to welding, although it can be

done is a speciality

welding'. He is a specialist welder from England

and has extensive

experience in Aviation welding, his last job was

building up blade tips on

jet engines. He said he wouldn't like to have to

do it !

We also discussed the possibility of Brazing!
My guess is that he is filling the holes by

Brazing or Epoxy( metal filled)!

Thanks for the details. BTW, are these side housings
really cast irom or possibly cast steel?
regards, Robert

Knowing Tracy it is probably JB Weld :) The point is why bother? since it is
known to cause crank case breathing problems.
