Hi.
I'm Wade from Thoroughbred Diesel, and today
we're going to talk just a little bit about
top side 7.3 Powerstroke oil leaks.
So talking today about top side 7.3 oil leaks.
And what we wanted to do is we wanted to kind
of...
We'll do a couple of different videos about
different old leaks that you have on 7.3 Powerstrokes.
They're common to leak oil, so we want to
point you in some of the directions to maybe
help you find the leak that you're having.
First off, wanted to talk about turbo pedestals.
The turbo pedestals on these trucks are really,
really bad about leaking.
EB valve and the EB solenoid here, they are
known to leak oil.
You can see this one we're getting rid of
it because it's been leaking.
You can get leaks on the top side of this
as well.
You can get leaks where the turbo mounts to
the pedestal.
And you can also get a leak where the pedestal
itself mounts to the engine block, really,
really common places for leaking.
So now let's get in the engine valley, and
we'll show you some places up as well.
So what we wanted to talk to you about now
is some of the places on top side to begin
looking for your oil leaks.
So just showing you some of the most common
places.
This is actually where the turbo pedestal
is going to attach to the engine block.
So you have your oil supply here, and then
your oil drain back.
You can get leakage here.
Of course, you can see the moisture around
the back of this motor block, and we've had
a little bit of leakage right there.
Then moving on up towards the front, and again
remember we talked to you about the pedestal
leaking from the pedestal itself or at the
junction between the pedestal and the turbo.
Now here at the front, Adam.
Your high pressure oil pump has got two lines
that run out of it, and these lines run to
each respective head.
So you can see this line here is running to
our driver's side head.
This line is running to our passenger's side
head.
You can get some leakage at these lines.
These are not factory lines.
This is an upgraded line that the previous
owner of this truck used.
What happens is you can get leakage between
the fitting and the head, or at the lines
themselves.
So kind of a better representation is back
here.
There's another set of feed pours back here.
A lot of guys use dual feed lines.
So just to show you here, this is going to
be...
On most trucks it's going to be blocked off,
but if you've got the dual feed lines, the
crossover junction line, you can have leakage.
So we can see this one better.
You can have the leak between there and the
fitting, or between the fitting and this factory
oil line.
Another place, and I'll let Adam kind of get
oriented here.
Around the IPR valve we can get a little bit
of leakage.
And then the back of the high pressure oil
pump itself, the big plate can leak.
A couple of different other little places
they can leak right there for oil.
So if you've got your all leakages at the
back and there's nothing towards the front,
then you don't have to worry about this.
If you've got moisture at the front of the
motor all the way back, that'd be suspect
of the lines where they adjoined the head.
Around the high pressure oil pump is another
good place to look.
And then make sure also it's not fuel.
Fuel bowls can leak.
You're going to have some residual oil moisture
in the top side of the motor.
If you get a fuel leak, the fuel can actually
leak into the valley.
It will mix with the oil residue that's in
there.
It's going to be a black liquid that you're
going to see, so you're automatically going
to assume it's oil.
Very well could have a fuel leak that's mixing
with the oil residue, which is a really, really
common spot.
You're going to get some PCV residue that's
coming out of the PCV valve.
That's going to have some moisture around
this area right here.
So if you've just got a little bit of moisture
right there, you don't have an external league,
you're not leaving a spot in the driveway,
you're probably okay.
But you always want to look in the engine
valley as a collection point for leaking oil.
If you see pooling oil in the engine valley,
you have an engine oil leak.
So that is our talk on 7.3 oil leaks.
7.3s, they're going to leak oil.
It's easy to fix them, usually pretty easy
to find them.
The top side leaks are the most common, but
we're going to talk to you about other leaks
that we see on the motor as we kind of go
along here.
So I'm Wade from Thoroughbred Diesel.
If you want to tell us about some of the leaks
you've had on your 7.3, comment them in the
comments below, comment right here somewhere.
And this video is part of a video series that
we've got going on with the turbo installation,
pedestal installation, wicked wheel install.
So you can check on those videos somewhere
right in here.
So thank you all for watching.
We appreciate it.
And as always, if you have any questions about
anything, just give us a call.
Thank you.
