F 250 7.3 Turbo diesel (White Smoke!! Help Please!!!)
 

My F 250 is blowing smoke out both stacks.It just came out of the shop 3 weeks ago after having trans rebuilt and rear main seal replaced.....Last Friday I filled it up with diesel at the same store I always go to.Then drove it 30 miles to Walmart.It was parked at Walmart for about 30-40 minutes.Started it back up and drove it about 5 miles and it starts pouring white smoke out of both stacks.The truck is running great.Motor sounds good.Turbo spinnin up fine.but all this smoke?:confused:I drove it home and the more I drove it the worse the smoke got.:eek:Its been parked since last friday except for starting it up to move it a few times.It starts fine no lugging.Rolls over twice and fires up.Does anyone have any info or diagnosis procedures to find out the problem?Thanks so much!!!Any advice would be welcome.:D

sounds like egr coolant valve

try plugging the block heater up leave on all night and start it in the morning...see if that helps..
