Hello all, I'm new to the forum and have seen alot of info on the blue/white smoke issues, but have yet to see anyone with dual problems. I have the blue/white smoke issue plus my heater is no longer working. Also using up coolant from the res. Bad EGR? Truck is plugged in for about 8-12 hours before starting and continues to smoke for several miles on interstate for about 8-10 miles then subsides. Once it's warmed up the smoke is intermittent at stop lights. Truck also overheats sporadically. No towing or heavy loads, just normal driving...I tend to baby it, so no full throttle antics or hard accelerating. I just babied it to the dealership and am expecting a phone call this afternoon, but want some non-partisian advice, since im sure the "stealer-ship" will surely try to rip me off... Truck has alittle over 95,000 miles on it and is stock with the exception of oversized tires. Regularly maintained with oil changes every 3000 and fuel filters around 12,000 miles. From what I've read it can be several issues, but if anyone can narrow down my problems it would be appreciated. Thanks!!!
