Default Help!! Not sure what it could be with this 4.0

I have a 1991 Ford Ranger with a 4.0, the problem is after the engine runs for about 10 minutes it starts spraying out coolant / water. The area appears to be on the left side if looking at the motor under the valves, could this be a freeze plug or is the gasket shot. There is no contaminents in the oil. Also some water is coming from the tail pipe is this normal from the combustion or is coolant / water going into the exhaust side.

sounds like a blown head gasket.freeze plug would leak all time,check the plugs on that side of motor if 1 or more of them has a clean white electrode the leak is on that cylinder

Ok so could this be a manifold gasket possibly, the leakage seems not be going into the oil....

not unless you have coolant gathering on top of the intake. most of the time the intake will leak coolant to the front or rear of engine.you can allways have the coolant pressure tested to find leak.checked plugs yet easy to do and it's free

I had coolant leaking from the rear of my engine, turned out to be an intake gaskets. Also had a freeze plug issue too with leaking coolant but with no milkshake oil.

So after all of that it was the intake manifold gasket. The plugs looked great. I could actually see where the gasket had blown out when I took it apart. Truck is back together and running strong. Thanks for the input guys....
