To me, it looks a little too dark to be just old/dirty coolant, and the small drops seem oily....
Thoughts?
In an older 855, WITHOUT the newer "Cealastic" head gaskets, it is almost impossible to get coolant into the oil / oil in the coolant via the head gasket. The only place oil can migrate into the oil from a head gasket is from the push tube cavity or the OP feed to the heads that are connected to the PT cavity. I have seen a low OP complaint from a ripped OP feed/PT cavity seal. It was very difficult to find and the only external sign was a large oil leak down the intake side of the block. The water grommets stick to the head/block via compression/ torqueing of the bolts. The grommets are made from a fibrous material that seals to the surfaces and in a separate cavity from the PT cavity. The PT cavity is not connected to any of the pressurized coolant or compression cavities and made of a rubber material but is connected to the cylinder head oil pressure feed. No chance of mixing oil and coolant there. If water grommets fail, you get the "Cummins Tears" which are the streaks down the block from the coolant eating/washing the paint away. Compression leaks will just blow out from under the gasket and the result is a "chirp" on laoded acceleration and a loaded uphill pull.It could use a flush for sure. If you suspect a leaking head gasket then there are products out there like the one below. They test for exhaust gasses in the coolant.
