Is it my intake or head gasket

[C.standridge]

Hey everyone Iv got a 97 explorer 140k miles. It started burning a little coolant minimal white exhaust. Has a rough idle but smooths out with acceleration. It’s the 4.0. Also I didn’t see any oil and coolant mixing.

Probably head gasket. Check your coolant level in the radiator. Another method is to remove the radiator cap (when the engine is cold), top off the coolant, and have a helper crank the engine while you watch the radiator. If bubbles and coolant come up you probably have a blown head gasket.
