Look at the front corner of the head-that is a common leak area on old head gaskets-external

I agree, use a good flashlight and you will find the seepage. The internal thermostat bypass passage between the block and head is right there. The ports are really close to the edge so the gasket is really narrow at that point.

When I had to change my head gasket last year I was mad at Cummins, Lol.
