I've been told by Kas that you can't have too much ventilation on the
TR3/4 engine. I run a 1" hose from the old sump vent (Modified as in
the old black book) and a 1" hose coming off the valve cover into a
nice big catch tank next to the battery.

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
