100% percent chance the thermostat housing is cracked. It's a problem that plagues the 4.0 SOHC Rangers and Mustangs. When you change the housing do yourself a huge favor and change the bypass hose on the bottom of the thermostat housing. New housing is like $70 from Ford part store and Amazon housings aren't worth the money. The new housing comes with a new thermostat so it's like killing 2 birds with 1 stone
DAMMIT!!! You are 100% correct. $400 later....I have more money than time at the moment.

Probably could have ignored it and made do till my engine swap but I didnt want to chance it even though it's probably been this way for over a year. Probably happened when i changed the thermostat as part of my new vehicle maintenance. 

When I buy a new vehicle l get all the maintenance up to date. Fluids I have a good base to maintain everything. It's expensive but oz of prevention is worth a pounds of dealership service dept repairs. It also minimizes bigger surprise fixes. 

Only time that has backfired on me was when I used radiator flush on my 87 bronco II. The gunk plugged the water galleys. It overheated and cracked both heads. I'll never flush a radiator through the engine again. 

Thank you black06xlt for your 100% correct prognosis.
