I still think the rings are shot OR the valves have been destroyed.

Plan is to drain the 20W50, put in 0W40 (used from the XF), pull the plugs and spin it over real good to try to pump oil into the valves. If I don't see oil on the plugs, or flying from the plug holes - we'll put plugs back in and try again to get it to start.

I still think either rings and/or valves are shot but I have several guys telling me it's gonna run again. This has turned into a challenge and I kinda like challenges... gonna play around iwth it tonight/tomorrow and see where I get.
