Exclamation Oill Leak Need Help

Ok so i have 1992 SC400 and it has a oil that gets pretty apparent. I had the Valve cover gaskets replaced hoping that was the issue but it's still leaking. When the car is running it looks like it's coming from the upper oil pan but i'm not sure. Has anyone had a similar problem like this. If so what was the problem ?

That's a pretty bad oil leak.
After you did the valve cover gaskets did you clean up the top of the engine real nice? If so is there new oil up there, or is it only dripping through at the bottom now?

When you did the valve cover gaskets, how did your spark plugs look? Were they fouled with oil or were they relatively clean?

yes and i don't see any oil on top of the engine. Didn't check spark plugs. It's only dripping from the bottom now.

It could be cam seals or the front crank seal.

If the top is dry now, just based on how the car is parked and where the leak is I'd be willing to bet it's what reaper said, front crank seal has probably gone bad.
