Coolant in valley between manifold and head
​​​​​​​
I have a 2006 Mustang GT with an M90 Roush supercharger I installed about 10 years ago. I noticed a small coolant leak on the top of the engine at the back of the intake manifold on the driver side. In that little Valley between the intake manifold and the head at the rear of the manifold I found some coolant leakage.I like to get a second opinion before I start. This is strange to me because there is no water passage between the manifold and the head back in that corner. Any thoughts?
