@250 deg. is ok for your oil temp and your tstat will have little or no effect on your oil temp.I need those ? answered.

And you think 250F is ok for an engine that is not race-ready, and hasnt even gotten over 2400rpm.
I'm sorry but thats not right. It should not be getting there, if the sensor is reading the correct data.

blackbeauty, have you replaced the oil temp sensor, or pressure sending unit yet. They would be the next thing to replace. If your pressure holds right now, then it probably isnt the oil pump

Vader86,

Thanks for the reply. I thought that I had replyed to this on Friday but I don't see it posted. Sorry about the delay. I have checked the oil temps with a cooking thermometer and the reading from the senor is acurate.

Default Different L98 cooling problem

Hmm.. I do not knwo what to make of your oil temp problem, but as a reference, Before my headers, my oil would get to 210F max after racing the car/engine or cruising th highway in high heat/humidity, and now after the headers it gets to 225F after driving on teh highway in hot and humid weather. My coolant however doesn't go much past 200F.

On mine the extra heat is due to the oil cooler line being less than an 1" from the headers.

Although I have never seen 250F from my oil (thank god), I don't think it should go that high.. It may be 'OK' for it to get that high, but it is not supposed to.. Our cars should idle effortlessly between 200-230F oil and coolant both for hours on end.
