Okay so me and a bunch of friends met up at Mcdonalds like usual and they all drive powerstrokes except for me since I'll be getting mine sometime this summer and one of my friends just bought a 97 7.3l PSD. I checked out his engine and noticed that smoke was coming out of his engine oil dipstick and a some coming out of his turbo. I'm learning more about powerstrokes the more I'm on here but that just doesn't seem right. My other friend has the same year and engine but his doesn't do that.
Is this is due to his engine simply burning oil or another cause?
