All right, friends. It's Len again here from 1A Auto. We've got another top problems for you. And this one's going to be on a Gen 4 F-350. Let's get started. Okay. So, you know me, one of the first things that
I always like to talk about in these videos is a safety issue. With that said, we're going to talk about
the block heater cable. Now, if you have one of these 6.7-liter diesels
more than likely you have a block heater.
That block heater, of course, is going to
have a cable that connects into your wall. With that block heater, if you were to take
apart the connection of the two pieces, you're gonna end up finding some corrosion in there. What happens when it gets corroded? A lot of times it will actually build up resistance
which will in turn cause heat. The heat is gonna end up melting the wires
in that area, and you could potentially have a fire.
So, the fixes for this is something pretty
basic. You can either replace that cable, which generally
speaking will probably be underneath some sort of recall, but if it isn't, well, replace
the cable on your own, or just don't plug it into the wall until you have access to
one. All right. So, underneath the hood, the next problem
is located right over here. It's called the PCV oil separator. The problem that happens with this is inside
of it it has a little spring unit with a valve.
The spring that actually is in there that's
supposed to make the valve go up and down and open and close as it's supposed to just
isn't up to spec the way it's supposed to be. Now, if you happen to notice that you have
an oil leak probably about at the upper oil pan gasket, more than likely it's because
you have too much pressure inside your crankcase system. The way that you could tell if you have that
pressure issue would be running the vehicle. I don't recommend doing this without safety
glasses on, of course, but you want safety glasses and hand protection, run the vehicle,
and then you would open up your oil cap. Once you opened it up, you would hear an audible,
like it's trying to let pressure out because inside the crankcase system, it's building
up pressure due to that PCV separator system not functioning the way that it should.
So, now, it's time to talk about fixes for
this. Of course, what you want to do is you'd want
to test to make sure that you don't have any blockages anywhere that you shouldn't. Overall, the most likely cause for this actual
issue would be, like I said before, the PCV oil separator, which is located right here. The little valve inside there just doesn't
move the way it should due to the spring. They sell an upgraded kit for this and I would
recommend it. So, the next thing I want to talk about is
located underneath the vehicle right here, the fuel tank. Let's talk about it. Now, if you were to look inside this fuel
tank, you would see a coating. For some reason, the coating that's on the
inside of these doesn't tend to stick around where it's supposed to do, and it'll start
to shift and/or come completely off of the tank and get caught inside the screen for
the fuel pump or fuel filter.
Some of the symptoms for this would be, of
course, well, lack of power because your screens are getting clogged up with a whole bunch
of gunk. You might also notice that your vehicle just
doesn't want to start for some reason, or, of course, you could start, and for some reason,
just kind of spit and sputter and act all funky on you. All right.
Now, some of the fixes for this, of course,
will be to drain your tank, drop it down and take a peek inside. If you happen to see that the coating's no
good, well, you're going to have to replace the fuel tank more than likely. When you do that, I would also replace the
filters that are involved with the fuel system.
That way there you can make sure you get out
as much crud as possible. So, the next thing I want to talk about is
the EGR valve cooler. It's located right underneath the hood over
here. And what happens with this is it actually
cracks internally and it'll leak coolant into the exhaust. And then, of course, once the coolant starts
burning, it starts blowing white smoke out your tailpipe. And now, for the fixes for this, of course,
you would have to replace that EGR valve cooler.
Well, like I said, it's messed up internally,
so there isn't much you're going to be able to do about that. And, of course, having coolant going into
your exhaust and then getting burnt and blowing out your tailpipe is not a good thing for
anybody. Now, if you were to look right here, here's
your EGR, here's your coolant tube that runs into it. And the issue is actually located internally,
right behind there. Now, the next thing that I want to talk to
you about on this vehicle is turbo hose blow off. That happens on this vehicle. It's very loud and very sudden and a little
scary. Let's talk about it. All right. So, let's say you're driving your diesel down
the road. Maybe you're towing a little something. You hit that hill, make you accelerate a little
bit. The turbo kicks in like it's supposed to,
thank you. Builds up that pressure like it's supposed
to, also thank you. But then you hear this loud pop. What was that? And all of a sudden, a sudden and drastic
loss of power. You pull over to the side of the road, you
pop the hood and where do you look, right here.
So, the cause for this, like I said, is located
right here. You have this plastic housing that's located
between the intake. And, of course, the turbo hose. The plastic housing gets dry, brittle, and
cracks. Once that happens, the pressure from the turbo
getting rushed into the intake, of course, blows this off. You hear that loud pop, and now you don't
have any pressure from your turbo system. And you're, of course, pulling unfiltered
air. Now, fixes for this, of course, would be replaced
this unit right here. You can find an aftermarket one that isn't
going to have this same problem. If it's cracked already, I wouldn't try fixing
it with something like J-B Weld or anything like that. It might be a temporary fix.
It might get you off the side of the road
to at least get home or to get to a reputable place to be able to deal with it. But it's not something that you're going to
want to keep on there permanently. All right. So, we had a lot of fun making this video. Hopefully, you learned something along the
