Intake leak?

yeah, that was my first guess. Wondering if this might be as simple as simply checking the torque on each bolt?




Well... nothing is leaking while running idling warm. I do not think the water hose is the culprit since that clamp is snug.
t-stat? that's a good possibility and an easy replacement. I'll stop and pick one up.
I guess the washer is free of paint on the one bolt too
