[C320-list] Oil leak

[Donald Lawson]

On my 2gm20 there was exterior oil line going from the block next to the starter,  goes up behind the engine, and ends up on thehead near the injector pump. Developed a pin hole leak on the back side and dripped oil down between the flywheel and the engine. It ends in banjo fittings with copper crush washers. I believe the two engines are the same except for another cylinder? Check the back of the engine above the flywheel housing. Can't hurt.

There are 4 or 5 droplet-size oil marks on the absorbant cloth I keep under the engine and I can feel some oil there. Any suggestions as to positively identifying the leak location and for steps to take next? Should I bring in a mechanic?
