Well, finally took the car into the dealer to fix the tranny/brake line/engine oil leaks. Got everything taken care of except the engine oil leak since I was told it would require a teardown. There diagnosis was as follows:

Oil leak is coming from, back left cylinder bank. They steam cleaned all under to see where the tracer die leaked out. It is a leak, not huge, but a substancial ounce a day or so.

Engine Mods:

-FMS/Meaux Stage 1.5 heads.
-Comp Cams 224/224 112 cam.
-Shortblock: LS1 block bored/honed .010" to pistons, Ross pistons w/ rings
-Stock rods w/ Katech bolts, FMS race prep stock crank
-FMS ported oil pump, SLP timing chain, ARP main studs
-Federal Mogul coated bearings, ARP head studs.
-Cometic head gaskets.

-All of these parts have about 14K miles on them.

What is the problem? How do I solve it? And what is the most cost effective way to go about it?

Thanks

Pull the valve cover, make sure the gasket isn't over compressed, then reinstall or replace gasket. If it's at the head/block junction, maybe new head gaskets.

You may have to get in there yourself with a mirror and see EXACTLY where the leak is coming from. That's not a super informative leak-location-diagnosis. Could be valve cover, could be lifter valley cover,oil sending unit, head gasket....get us a little more info.
