There are Usenet clients for Android. I don't use one. They
allegedly all suck. I run linux on my machines, so I just SSH into
one of those and fire up the CLI client I've used for decades. This
is probably not useful to most people.

Yep. The checkball is on the inlet side of the oil pump. The
seat is cut into the actual body. There are a few ways to fix it:
1 - Buy *two* new checkballs. Remove the spring and checkball that's
in there now. Put one of the new checkballs in there. Grab a punch
and gently tap the new checkball with a small hammer. Make *sure*
you're square on the checkball and not hitting the sides of the
tower/body. Remove that new checkball (it'll have a small dent in
it!), put in the other new one, re-assemble. If you don't want to
pull the pump apart, this is the most easiest solution.
2 - Same thing, but instead of a new checkball, use the end of a
rocker end of a Shovelhead pushrod. Same thing.
3 - If everything is apart, gently lap the seat with either a new
checkball (if you can find a tool small enough to hold it) or
aforementioned pushrod end. Obviously, if you do this, you have to
*very* thoroughly wash every single orifice and part of the body
afterwards. Lapping compound in tiny oil passages is a very bad idea!
