So my 2012 crew with a 5.7 (192,000 miles ) is running the oil temp up to 270 before we shut it down. The coolant temp just hits 203. I have replaced the thermostat and the coolant temp sensor. No codes. Any ideas on where to start looking would be appreciated

 

Have you checked the oil coolant? I’m here to find out more info on that particular piece as that’s where mine is leaking from!
