[Spridgets] Oil leak - crankcase ventilation?

[Ron Soave]

If it is leaking that badly and when parked as you say, all the PCV in the
world won't fix it. The rear "seal" needs to be addressed. The very best thing
to do is to verify crankshaft straightness, get it align honed and do Paul A's
rear seal kit on it (check the archives or I can dig out instructions). This
setup has worked for 7(!) years for me on a very high compression engine that
only has ambient venting, not positive venting. Doing Paul's kit alone may do
it, but while you're in there...

Looks to be coming out the rear main seal area.
