what kind of motor and year is it. the only experience i have with coolant leak on top like that is when my intake manifold started leaking. 5.4l 2001 f150
give me the info on your motor and i can look on alldata and see what i can find

I would say that is what the deal is. Intake manifold. I've seen it on 4.6 and 5.4. Make sure to get the revised manifold- aftermarket made some changes to try to prevent this reoccurring.

Nope Ive had the same problem with mine and the intake manifold cracks where the crossover tube meets and causes this. A lot of people have had this problem. I used some prestone stop leak in mine and it has stopped it. Otherwise you need to take the whole upper intake manifold off and replace it.

I agree it most likely a crack its about a 4 to 5 hour job start to finish.

i did mine a few monhs ago. the hardest thing i ran into was disconnecting the fuel lines from the fuel rail, after spending about 30 min with that it was no problem doing the rest. i have no mechanical experience other than oil changes and basic stuff. took probably 7-8 hrs over the course of a week. little here and there.
