It's always fun to see your oil pressure gauge plummet to zero suddenly.
'68 W200 w/318. Just recently dropped the pan, cleaned out 3 inches of sludge and cleaned out oil pump at the same time. Full pressure on startup, dropped to zero when warm. No external leaks, never been an issue before.
What would those wiser than I (you guys)check first?
