My 1995 Nissan 240sx has a strange problem. It seems to have been leaking oil, although my mechanic can't seem to find the leak. I have to add oil once between oil changes. I can usually stick the neck of the bottle of oil into the hole for the oil. When I added it today it appeared that something metal was blocking the neck from going all the way in.
I think that the valve pan is bent up towards the oil filler. What may have caused this and does it need to be fixed?

If your mechanic can't find a leak, you're probably burning oil. This is a sign of worn-out rings or valve guides, I think.
The metal blocking the oil filler hole probably was a rocker arm. These are part of the valve train that opens and closes valves to let fuel and air into the cylinder, or out. When the engine stopped, this particular one happened to be up. To verify this, start the engine and then stop it, and check the oil filler hole again. If the blockage is gone, then that was the cause.

I would be careful now, not all vehicles have valve covers to where you can see the lifters or what you would call valves when you remove the oil filler plug. Some vehicles have that cover so when you add oil with a funnel you dont end up damaging your valves. I would look more into it before you take your valve cover apart. Now to your oil leak, it may be a valve cover gasket, oil pan gasket, a seal, and or you may need a PCV valve which is located at most times at the top of your valve cover.
