6.4 l oil overheating
2008 6.4l with 60000mi, after driving for 15 mins I get a decreased engine power message and the engine temp guage spikes to max. Engine coolant temperature stays normal(200 deg approx), but engine oil temp increases to 260+. Ford dealer replaced engine oil cooler, thermostats,coolant and oil temp senders, water pump and front cover under warranty, but problem still persists. Thinking there is a coolant restriction somewhere going to the oil cooler, but not sure...any ideas?
