Oil Leak 1995 LT1 Engine
In performing an oil dye test, I noticed a leak on a bolt behind the intake manifold. This "bolt" appears to be under an EGR valve. I checked the FSM but did not see anything conclusive. Help please.

would say its the back of the intake, Lt1's are notorious for intake leaks. Pull the intake off take a punch and punch holes in gasket rail and the intake silicone it and put it back together

Time to take the intake off and re-seal it.
Not to difficult of a task to do, alot less messy than earlier SBC since on the LT1 the intake has no coolant in it.
Several things to take off in order to get the intake off...but nothing difficult. There are a couple of bolts that are hard to get to...the lower EGR valve bolt and couple of the intake bolts have limited access, but still a do'able task in a day.
Good time to replace the valve cover gaskets too.
