However, be sure and check to make sure your valve covers aren't leaking somewhere. You may need to run the truck longer to burn any solvents or oil residue off.

There was no engine oil cooler on these trucks unless someone added one afterwards. They did have an automatic transmission fluid cooler on the radiator, though. You probably have an automatic trans radiator.
Yeah Forgot to mention my temp gauge doesn't work, that or the engine never got warm, which I doubt. I was partly wondering if some of the smoke was just old grease and oil burning, sounds like it is. Thanks for the help Yall!!
