lb7 oil leak

[lb7lbz]

i have an 01 2500hd that i lost the cam pin on so i junked that engine and bought a 03 engine out of a c4500 tow truck. not as straight foward as i had hoped but its up and running. only prob i have is that i have an oil leak that is tough for me to spot on the ground(no lift). it appears to be coming from the piece that the oil filter screws onto, but where that piece attaches to the block. its deffinetly starting above the upper pan and below the valve cover gaskets. anyone ever seen this?

Check the engine valley. A leak there could be due to a turbo oil feed/return line or something related to the CP3, and could run down the back corner of the block.
