Coolant under valve cover.

I bought this 1967 F100 with a 352 fe engine from a friend of mine about 3 years ago .This truck sat for about 8 years got it running like sewing machine . I wanted to clean up the engine do a little detailing to it . When I taken off the valve cover I noticed small amount of antifreeze in the oil . I started it up and watched it and every once in awhile little beads of antifreeze in the oil . The oil looks good and the antifreeze looks clean I'm thinking intake gasket I hope. The 352 is still stock with about 47000 miles on it.

Most likely source is intake gasket.

All the other possibilities i can think of are cracked something.

Id change the gasket first. its easiest even with 80 lb manifold....

Thankyou for your reply. I was thinking same thing I just want to make sure before I dig into it. I've got a set of intake gaskets I guess that'll be a project for the fall when it cools off in the garage.

My guess would be head gasket.
