If the dipstick tube is the only place you're losing oil, there's a cheap
felt washer available (VB, TRF, etc.) that fits under the dip stick cap.
Don't use anything that will completely seal that hole. The engine needs
to run with a slightly negative crankcase pressure. That opening acts as
a vent.
If you've got oil seepage from other areas, like the front seal and pan
gasket, you'll want to take a real close look at your crankcase
ventilation system. Like I said, Spit engines need to run around 2-3
pounds of negative pressure. Remove the oil filler cap and rig a
temporarily air tight plug with a vacuum gauge attached. Check the
reading with the engine at idle. Anything from 0 to a plus pressure will
indicate a clog crankcase vent system.
