I recently took my cowling off to work on my engine control cables and immediately noticed some green fluid dripping from the sniffle valve onto the lower cowling. Any ideas what it is and how to deal with it?

It looks like blue dye in 100LL.

Would some oil mixed with the 100LL make it green? Because it is most definitely Green, not blue.

Fuel dye

BTW, it is good practice to have a drain hose/line connected to the valve so that excess fuel that drains out goes overboard instead of laying in the bottom of your cowl.

As the posters above said fuel mixed with oil, probably from your sniffle valve if you have one installed.

Do you have you sniffle valve plumbed so that it drains outside of the cowl?

Cheers
