Another noise lifter question

[pb24]

I'm trying to find out which lifter is making noise. I listened with a mechanic stephascope and it sounded like it was coming from under the right valve cover, I pulled it off and tried to move the rockerarms to see which one had the play but they where all good, and then I ran the engine but oil leaked everywhere. Does any one have a easier way? Its a 68 charger with a 383

if I have to run an engine with the valve cover off I use a thin Cardboard wall 6" high to keep the oil from going everywhere
noises in an engine can travel & can be hard to determine where thay are coming from

Also, try checking the fuel pump. I had a 383 making noise that sounded like a lifter and it turned out that the pump arm was not returning completely, creating space between the pump arm and rod. Just something to check- things aren't always what they seem.
