I shudder to think what will happen once these engines get into the hands of the majority of the independants.

Yeah, you and me both considering most can't fix a 6.0 ... imagine what it's gonna be like like these hit the indy shops Posted Image

Keith,

 

Don't think I haven't heard that from some fleet guys that come into our shop asking for advice.

 

The best was a pair of guys working on a Duramax, and they said first it was hard to start, but they got it running by cracking the lines to the injectors. I looked at them like a deer in the headlights.

 

Afterwards, they said the check engine light was on, and it wouldn't rev up all the way.

 

Dufus number one then said, "I floored it, and our third helper opened the injector line to one injector at 2800 rpm, he was knocked to the floor and sent to the hospital." He was unconscious. They didn't understand what happened. I think he's alive. Fucking idiots. At that point I still didn't know why they did it or care. I blew them off.

 

If I'm over my head without the tooling or training it goes to those who are.

 

We refused to work on the truck.

Thank you Jim. That picture is worth looking at to make the point about respecting high pressure fuel lines. It's like a kid watching porn for the first time - they want to look away but they cant stop watching. It leaves an impression. Cracking open any common rail fuel line while running or until the pressure has bled down is very dangerous.

Where I first ran across this type of injury was when I was involved with the fire department. I would drill it into the guys about caring for the lines attached to the jaws of life tools.....

 

And these tools run nowhere near the pressures involved in the modern diesel fuel system... Just the thought of running one of these without the valve covers is cause for concern...

It's funny how things play out in the daily journey of life. I was working at the mountain today and I was standing about 2 feet away from a line with 4000 psi running thru it that holds the brakes open on the lift. I decided to look a little closer and the line was actually starting to chaffe pretty bad on the frame of the hydralic unit. 'Nuff said there.

I also was wanting to get a book on hydralics and guess what? Now I have a good source to go to.

Sorry to wander extremely far from the topic!
edit for sp.

I had a boss that that was his most common diag procedure on a diesel...cracking the injector lines.

 

Yes, I am kidding, but we ARE going to see this.

 

"Warning? Pfffft...That's not for US!"

That is pretty nasty. Ive had guys actually tell me to check for missing cylinders to crack lines like on old 5.9's with p7100 pumps.

ahahahahah sounds like it.On the new common rail stuff you can use diagnostic equipment but on older stuff like that which i havent actually got to wrench on.What would be he procedure???I mean i think there is nothing electronic on 5.9s until 1998 with the 24 valve.

OK... so, I finally got around to getting the VCs off this truck.... Read "reflash gone wrong" to see how most of my days go.

 

With the valve covers off, I put dye in the secondary filter.... started the truck and let it run.... of course it ran like a champ.... no miss - couldn't tell about smoke with the exhaust hooked up.... enough distractions that I didn't think of it, anyway.

 

With no obvious leaks, we start getting a little braver.... With the covers off, we perform the high pressure fuel test... Now is not a good time to be waving your meathooks around the rocker boxes.. but the temptation is ever so great.... Use your black light... If you absolutely feel the need to "feel" for it... use some strips of stiff paper... What you can't see might not be too good for you.

 

Anyway, nothing obvious....

 

Out with all the glow plugs and spin the motor over - lots.... and lots and lots... six cylinders are blowing mist out of the glow plug holes.... varying amounts from very little (on a cylinder constantly flagged) to HO - LEE PHUQUE on a cylinder known for early damage but rarely if ever flagged on this concern.

 

Tomorrow, the inverted fuel test. Dwayne doesn't like this one and I don't blame him. Done with poor planning or consideration, this test could be life altering.

I currently have one that I put an horizontal cooler in and it ended up bending cylinder 8. Now I got to do another short block.

 

You know I have had a few 6.0 hydrolocked pretty good on a few cylinders and no damaged occured to the base engine but with the 6.4 it's seems like it is alot more sensitive to hydrolocking. 6.0's hydrolock while driving and can be saved alot of times. 6.4's hydrolock while driving and shoot a rod out the block.

Here I am working on the "HELLUVA" truck...

As you can see, I have borrowed Rexs crank seal installer.

 

Here is the inverted injector test

And here it is with the cab removed - for clarity

Oh man, good stuff there. Laughter is the best way to make thru the day when dealing with something like that. Of course it doesn't hurt when there are thousands of comedians out of work and they all end up being mechanics. Posted Image

I have two explanations.. pick the one you like best...

 

Creepers are for pussies and sensitive new age guys.... we'll not be havin' none of that o-fay crap on my watch....

 

Parts of me are no longer as sleek and slim as they once were... the vertical space consumed by the addition of a creeper can reduce the possibility that I might fit under even a lifted truck....

Posted Image I totally understand the clearance issue. But I personally dont like being dirtier than necessary and my floor is frequently wet in spots... laying on a cold damp concrete surface is supposedly not good for the human body. However, if I had spiffy coveralls like you I might behave differently.

 

 

 

Sincerely,

A. Pussie
