C4 Anti Freeze Weep

Brand new member and finally bought my first corvette (1985) at age 60. Can't believe how much fun it is to drive after being in 4 cylinder cars for the past 20 years. Got my new ride home and noticed a small amount of green fluid (maybe2 drops) on the front of the intake manifold below the thermostat housing next to the front torx bolt. Have driven the car several times and this occurs each trip but evaporates before the next trip. The top radiator hose isn't leaking and it doesn't look like it's coming from the gasket of the thermostat housing. Any ideas?

Intake manifold bolts. Take one out, smear some RTV on the threads, replace bolt. Then do the another. Front 2 on each side.

Use a bright light to help you find where it leaks from exactly.
It may be just a loose bolt as others have suggested, but best to investigate and look carefully before it becomes a bigger leak.
