72 318 Scamp. Low oil pressure 1 minute after startup.

Think that I will look it all over after work tonight. If I need a pickup or pump I will get that so the way. They was just some hard bits in pan. Looked like supper brittle rubber or plastic. No bearing shavings.
The super brittle rubber is usually time hardened valve stem seals. That equals replacement time. They will continue to break down and plug the oil pump pickup and pump. Ask me how I know.
