Hello, so recently I've been running into the issue of my oil temps running a little warmer then normal. Car runs fine in city but as soon as I get on the freeway my temps start to creep to 250f and sit there. Only remedy I have it turning on my heater and i watch my temps go down to almost 230f. Did a water pump test to see it was spraying into the reservoir which it was.

Could it be my thermostat? I also noticed a OFHG leak that's not terrible and its the only leak but I saw on a forum someone said the oil can contaminate the coolant in the filter housing if there's a leak. My modifications so far are JB4 usually map 5 or 7 on e40 mix, stage 2 lpfp, bms 5 inch intercooler, doc race charge pipe, vrsf j pipe, xhp flashtool stage 3, vrsf catless downpipe.

Anyone got a clue on what's going on? Started about a month ago before I installed the BMS intercooler and nothing changed after install temps wise. Also i cannot log my car, don't have the JB4 app yet and I have a locked DME.

*Edit: I can also get pictures and videos as well for better representation, my suspicion is possibly intercooler? i know its not sufficient for arizona temps but I will be driving when its 60f and raining out and it will still have hot temps while cruising without the heater on

Yeah that is an issue then. I'm guessing you have an oil cooler. Is anything blocking the cooler core?
