[FC] new oil leak, pressure related?

[corvanatics@corvair.org]

Hi All,

have a new oil leak on the brier, seems to be blowing back @dipstick tube.  removed vacuum lines, plugged it where the hose connects to carb tube, and removed the pipe coming up from the top shroud.  this significantly decreased leak around dipstick tube and indicates i probably need a good cleaning of the top shroud pipe

however, still seem to be getting wet around the top of the dipstick tube, i think this indicates i still have stoppage somewhere.

the pipe that comes directly out of the shroud is still connected to top cover, however i soaked this in carb cleaner and cleaned really well @8-10k ago when i had cover off

is there anything else that could be causing pressure, or do i need to remove carbs, top cover, etc and check that pipe again

as always advice is REALLY appreciated
