I have a oil leak when the engine is running and/or idling but It doesn't leak when the engine is off. When I turn the engine on and start it, I tried looking for the leak but I can't find it. I only see drips but I don't have a clue where it's dripping from. What can cause an oil to leak while the engine is running and/or idling but not leaking when it's off? It's on a Chevy Suburban 1999 K2500 7.4L. 454 big block. Thanks!

That means that it is leaking from a pressure point. The most common point for that to happen would be the oil pressure sending unit. Follow the leak to it's source.
