Repairing a 2017 Chevy 350 Diesel Turbo that is DRINKING Oil. Check This!

Okay, y'all. We're working on this truck today. Low mileage truck. It's got It's got uh 60,000 mi on it. It's got the diesel in it. Let's fire it up. Okay. It's got the uh It's got the power stroke 6.7. That's 350. This thing is ranking. Ranky boy. We got to figure out why. I mean, it's just drinking. I mean, like like maybe gallon a mile drinking oil. We got to figure out what it's doing. I'm going to pull this cap right here. Push the oil cap. Hear that? That thing's building all kinds of pressure. There's no there's no pressure. It's building all kinds of pressure. So, uh, is it the turbo? Is it the turbo? Is it the the air filter? This is a new one, too. This is a 67. It's going to be a 17 model, but it is just a drinking oil. Crazy right now. That cap off. Cap back on. Cap back on a few minutes here. Can see it. Listen close and I'll go take that cap off. See if you can hear it. Here we go. Ready? Got to figure out what that is. What is doing it? Why is it doing turbo? Turbo blowing blowing oil back. Maybe that's it. Maybe. I don't know. We'll have to find out. Stick with us. Give us a thumbs up filming it. And uh we're going to see if we can't find out what's going on here. Okay, guys. This damn thing here, the V um CCV crankase ventilation. Okay, that thing stopped up. I I guess these things are stopped up. They're ballooned out. That would probably be an indication. I probably hit that. They're ballooned out on the sides. That thing goes back in there. Okay, this box here, I had to take this box out. I didn't have to, but I did cuz I wanted to get more. See exactly what was going on. I got to clean this up. And then I got a new one. Right there is the new one that goes in there. It just slips off down in there and you're done. Um, and you got top there that goes on it. And then bolts go back in the top and bolt it back down and it should be good to go. I'm going to spray it out real good with some carb cleaner. Try to get it nice and clean and then uh we'll go back together with it and see if that's the cause. The thing goes back there. You got to pull your fuel filter out. But it ain't no problem in this truck. It's all done by hand. There's a bolt hole there. Thing sits like that. There's a bolt hole there. Two bolt holes back there and a bolt hole there. It's pretty easy to get to. And there's a couple of O-rings in there. But just make sure you got oil on them O-rings when you go back together. And uh wham, bam. Thank you, ma'am. It's done. Let me uh let me get to cleaning on it. And then uh I'll put it back together. I'll let you guys see it when I get it back together here. Okay, y'all. There's one bolt hole there. There one bolt hole there. And there's two bolt holes back there in that one. That's it. Four bolt. They're all 10 millimeters on this particular truck. This is going to be a 20 late 2016, early 2017 truck by the manufacturer date. Um, so that's what we're looking at. I did take the fuel filter out. Fuel filter goes there. It's just a cap that goes in there. The only reason I took it out was to get these fuel lines out of the way. Move these fuel lines down. Other than that, it's easy. Just stick your hand back there and get these two started. Them two back there started. Once you get those started, I used an extension um with a swivel and come way up here with my impact wrench. Put them in. Put that one in there with my impact wrench and put that one in with my impact wrench. Took me five minutes once I figured out where the lines was. You got to jerk it pretty good to get this unseated out of there. Had to pull up on it pretty good. So, I'm going to have to wiggle it back down in there, get it set. These back tube got grommets in it, so it won't overtighten. That one's got a grommet, so it won't overtighten. That one's got a grommet, so it won't overtighten. So, it shouldn't be that big of a deal. Um, getting it in place is kind of a pain, but other than that, it should slide right in. I slick some oil around that, got it oiled up real good. I'm going to try to push this thing back in there and lock it back down and see what I can do with it. I'll let you know uh when I get it back in there. Okay, y'all. That thing's back in there. Put the fuel filter back in it. Put the clips back on it. This one goes there. You just kind of pull and twist. Pull and twist and that thing will pop off and you're good. Get your four bolts back in that and you're good. That fuel filter really you just you squeeze on these things and the damn lines just come off. Push that one down. The lines come off. Push pull that out. push these down. Lines just slide right off. I mean, in hell, it ain't nothing. You don't need no tools or nothing. It just comes right off. So, that's all easy. I got to get all these tools cleaned up. I'm standing on the toolbox here. Um, then we'll fire this thing up. See if it fixed it. Hope trying to get rid of crank case, excessive crankase pressure. So, we'll see here in a few minutes. Let me uh let me get all these tools cleaned up and get everything back in my toolbox over there and we'll see what we can do with it. Okay, y'all just hang tight. All right, y'all. I got it running. Y'all going to know what I know, I guess. [Applause] Make sure last time we did it, dude. [Applause] Give a little gas. Make sure we ain't got a fluke thing going on. [Music] Okay, we're back over here. Here it go. Go. Fix it. You got crazy external pressure. That box back there. CCV valve. Crank. Crank case ventilation valve. Crank case ventilation valve. That's what it is. So, fix this one. Need that piece there. I bought it from the local parts house. It was 150 bucks um for the for the filter for that filter there. 150 bucks. Right there is the part number on it. Right there's the part number on it. $150. It fixed it. It was a extreme pain in the butt to change. It wasn't that bad once I figured it out. Once I figured out there's only four bolts on it. This one ain't bad at all. And this is a Let me double check this. I ain't lying to y'all. This is a nine of 16. Nine of 16. Y'all, if you like what you see, give us a thumbs up for filming.
