Have a 95 just had cracked heads. I went with aftermarket heads that are thicker. You have some things you need to check first. Do a Pressure check on the cooling system. Engine running and engine off. You could have a turbo going bad also but doubt ful since it clears up at speed. Sounds More like you may have a Problem with your fuel system. Aleaking injector or a bad fuel Pump. Will white smoke with a head/headgasket failure or way to much fuel. Since it does clear up and you didnt say it overheats or pushes water out of radiator i would be more inclined to think you have a bad injector. With that much mileage i would Redo the injection pump and injectors if you find a bad injector.
