Help, head gasket question

[City_Hunter]

Hello,
I have a 1994 E420 with 170K Miles. This picture is taken from the bottom from the location of the steering gear. I found some residue which is clearly coming from the head gasket but its really minor. Should i do a head gasket replacement or no? I don't want to do it but if I have to do it now is my only chance since I have most of the engine apart.
Thanks,

If the leak is minor and you are not losing any significant amount of antifreeze... just ignore it. Yes, replacing the head gaskets would be nice, but it's a ridiculous amount of work (or, insane cost to pay a shop).
