White exhaust, coolant loss
Last year, 56,000 miles ago, had head gaskets, oil cooler,SCTs and studs put in. All stock. Last week developed a hairline crack in radiator at top hose inlet.
Have been adding and adding water. Some gold coolant, but not maintained the 50/50 mix.Been chasing the crack with JB Weld. Two days ago it developed a 'hollow leg', and took gallon after gallon of water. I can hear the water go [I]somewhere[I], but not until today found the puddle on the ground. Under the Muffler! Very, very sluggish starts, like my Optima yellow tops are drained. LOTS of white smoke under load, warm or cold. I took out the EGR valve and cleaned off the modest build up of carbon. Seemed to travel freely. Appeared to be dry, no moisture on valve or below it.
Truck is 2005 F-450 with 141k well maintained miles. 4X4 DRW. Hoping the forum can give me some ideas before I am relegated to the stealership.
