Hi i have a early 99 7.3 powerstroke with 170,000 miles. I've noticed only on heavy acceleration my truck blows blue smoke. The higher the setting on my dp-tuner the more blue smoke it produces. I checked my oil level and it doesn't seem to be going down. I did the oil cap test(putting the oil cap upside down on the oil spout and to see if blow-by will blow the cap off) and it passed. I checked for seepage of oil in the intake tube where the ccv meets the intake tube and there is none. I do have a bad #8 injector which makes a loud knocking noise after the motor warms up. Any thoughts or ideas what could be causing the blue smoke? All thoughts and ideas are welcomed!!!! Need Help
