[Fot] block venting

[Mark Pendergrass]

Family, earlier post made mention of venting the block. Seem to have alot of
pressure build-up even to the point of haveing to wrap a shop towel around the
rocker cover filler cap prior to getting on track. i have a finned aluminum
cover with a pretty small vent hose. Would it help to weld a larger bung on
cover to accept a bigger vent hose....this is driving me nuts!!! The usual
venting stuff we do has been done.........i think!    Thanks in advance   Mark
