99 ranger 3.0 flex fuel engine, overheat
1/99 ranger with 3.0, 200,000 plus miles. Runs good started overheating. Flushed system, changed thermostat, replaced water pump, checked compression (110-125) it is now building up pressure can anything other than heads or head gasket cause this. Have heard could be intake. What is the best way to test if possible. This shows no other signs of head problem unless compression is low I'm not sure how much this motor has.
