<VV> VV re: oil out of the dipstick tube

[Brown, David]

I cut off the tube, as you suggest, on my 110 several years ago, but it
had no effect what so ever.  The pressure in the crankcase still pushed
out the oil that is still getting splashed around in the crankcase, so
the new level of the dipstick tube made no difference.  What worked for
the next 2 years (before I sold the engine- still running great) was to
relieve the pressure by running a hose from the oil cap to an overflow
chamber (aftermarket radiator use), & then to the back side of the air
cleaner (where it couldn't be seen).  This way the pressure was relieved
& excess 'bad' gasses were re-burned as well.

I dont recall seeing this, but got the answer here before.  You can pull
the oil pan and break the extra protruding dipstick tube off inside the
engine at the level of the crankcase with a screwdriver.  This will put
the base of the tube above oil level. 
As Bob Helt pointed out GM extended the tube below oil level  to keep
crankcase fumes from coming up the dipstick tube and getting into the
cooling air that could make it to the heater.  But with an older engine,
I think you will get more fumes from oil burning off the engine.  You
can also drill a small hole at the tube rather then snap it off in the
oilpan.  In a case like my converitble though, it would pour oil out of
the tube at 80.  This would pour over the engine and smoke us out.  So
breaking the tube off in the case solved it.  Also if it is an earlier
engine, putting a late dipstick in with the better seal will help.

I will change the oil this weekend; and see what the results are.  If
it's still pushing oil I may have to add a larger breather for now.
