Oil and Antifreeze leak

Hey all,
I'm noticing an oil streak coming from the block right where the exhaust manifolds mounts. It's at the front, right underneath the #1 spark plug. I've been keeping an eye on the dipstick, and it doesn't seem to go lower than the add 1 quart point. So essentially if it's been sitting, and I check it, there is barely a drop just below this add point.

There is also a bit of antifreeze mixed in the drippage as well.

Any ideas would be appreciated.

Sounds to me like a freeze plug is leaking. Fairly easy fix if it is.

Thank kenv for jumping in. I took another look, and the freeze plug is all good. It's actually coming from the valve cover gasket. Gonna have to swap that out for sure.

Appreciate the help. Dogs rule!!

Get a Ranger valve cover gasket. It is reusable and does seal. The cork one is useless I have tried.
I think the part number is in the tech link at top of forum. If not let me know and I can look it up. You will have to get from Ford dealership it is a Ford part. Maurice
