<VV> Help - Oil Out Dipstick Tube

[Shaun]

Corvairs have the end of the dipstick tube in the oil for a reason, to keep 
blowby fumes from escaping into the engine compartment and then into the 
heater.
Short of a rebuild, the "proper" way to deal with this problem is to install 
breathers in the valve covers. The way it's "usually" dealt with is to drill 
a hole in the oil cap or filler tube and run a hose through a hole in the 
shrouds.
The reason it does it in the first place is because of poor cylinder 
sealing, either worn rings or cylinder walls or both.  A rebuild would solve 
it, but you can drive it a loooong time like that if you add a breather. 
Keep your revs down in the meantime.

yea, Vairily ... Shaun
