Oil most certainly can cook. At high temperature oil beaks down, oxidize's, turns to sludge and varnish. This is the whole reason why they designate a timeframe and mileage to remove it from your engine.

I figured since the oil was getting hot that I was cooking it

If you are indeed seeing oil temps @300* then you are cooking it. It needs to come down atleast 30* to be what is considered safe. And even then it would still be cinsidered high. Anything over 285* is bad.
Your oil temps should only ever be 40-60 over the coolant temps.

If im not mistaken they did thats why those motors did not have that prob. Im going to install a after market oil cooler and see what happens

Obviously an oil cooler will help. Since your now adding capacity and a direct way to remove it from heat and cool it.

You can also get a lower temp thermostat. If you can keep the motor running cooler all the time this would also help the oil be cooler.

The real question is why is your oil temp that high in the first place. Thats way high.
