[QUOTE="Diabolic, post: 1521568, member: 18314"] I have a 97 Powerstroke, and yes I realize this isnt the obs section, but I have E-Fuel, spider with intercooler, Upgraded HPOP, 160/30 Injectors, and a KCTP38R Turbo. I figure it's more like a newer Powerstroke 7.3 than an obs Powerstroke 7.3. I'm getting a light haze of white then blue/gray smoke when the truck is under a load, say 10psi, and lugging at lower 1500ish rpm. It does clear up once the boost hits 15-20 psi and it nears 2600-3300 rpm. It also has a really strong odor of fresh burnt motor oil when it blows the blue/gray smoke. At wot the ICP pressure looks great at 2500-3500, IPR% is 38-40, fuel pressure is 55 psi. I pulled the downpipe and its sooty black and dry as a bone. I flipped the oil cap and it just lightly vibrates, but when removed it does have a steady stream of blowby smoke, 300,000 miles. The Provent 200 catch can will gather about 1-1.5 quarts of oil every 3000 miles. It has no oil leaks, and runs like a champ. On cold mornings 50 or below, it will fire right up, shake for 4-5 seconds then smooth out. White smoke heavy for 8-10 seconds then just a light haze of white for 1-2 mins. If I plug it in at night, I get just a very small puff of white smoke. I have checked the fuel filters and there is no oil in the diesel. I'm stumped here. Maybe valve guides? Turbo has about 1600 miles on it. I'm certain its burning oil because of the smell when it blows the smoke. [/QUOTE]
