The truck I've been working on is an 05 f250 with a 6.0 diesel and 170,000 miles. The complaint was white smoke coming out of the exhaust, great its the egr cooler, (which it was faulty). The owner noted no lose in power, or excessive coolant temperatures, and the exhaust never smelled like coolant, but there was some coolant lose over time. So he wanted to delete the whole egr system and I did and finished it today, but guess what when it got warm it started smoking again, lots of power but white smoke that turns to a black haze then clear at the tail pipe when it is floored, he did say that the temp gauge before all this happened about 4 weeks ago, the temp gauge shot up some but settled down again, (up next to the red). So now I'm thinking a cracked head??? There was evidence of water in the oil but not very much just enough to turn in slightly milky. I'm not ruling out a blown head gasket but a cracked head seems more likely. Any suggestions. Sorry for it being long winded its been a day.
