Could it be that your previous purge did not clean out the engine fully (especially since it ran WVO)? Could it be that you jut got the "easy" gunk and that the gunk that was not purged has now gotten loose, causing the current issues?

I'm a newbie, too, so take everything I say with a grain of salt
