What A Failed Injector Looks Like
 

Got these from a buddy. Someone put gas in his fuel tank. Be careful at the pump guys!!!

that happen to just one? how did the rest of the engine hold up with that chunk of metal flying around the cylinder?

So far so good... These aint no duramaxes... They can take a beating. :D

We sent a 3/8" washer through jasons engine. He cranked it up, heard it go through the intake, bounch in teh cylinder a few times, hit the turbo and out the pipe. Still runs like a top! :D

durn bobby when did you do that

That's why I pump my own fuel.

ditto^

wow..thats some wild looking stuff...had a lady bring my uncle her 03 cummins, late one night she put 5 gallons of gas not diesel in her truck and drove it home down the highway she cracked 4 pistons, messed up part she had 350,000 miles on it she hauled horses, when we tore it down the rod bearings looked almost new i was surprised.

What causes that to happen? I know gasoline is thinner than diesel, but what causes the injector to explode into pieces like that when gas passes through?

the gas will take all the lubricity out of the diesel and that injector probably got hot and just came apart from overheating

gas will make a diesel get real hot that is why the diesel pump has a green handle and a big nozzle:argh::argh:

Not all diesel handles are green. I wish green was an industry standard but it isn't. Some of the stations around here have all green handles. Gas and diesel.

BP fuel stations are the opposite, black for diesel and green for gas, so watch out.

but back on topic. guys

thats the reason i had to drive 4 hrs to rescue my buddys dads truck in ney york. put the green nozzle in his 7.3 powerstroke. drove till it couldnt move the camper anymore. i drove up there with a backup truck on my trailer, swaped trucks and got his home. drove it into the garage, popping and sputtering. opened fuel filter and smalled the gas. drained tank. filled with fuel and new filter. fired her up and she ran like nothing happened. still running today. no issues.

if u cant tell which one is which by the smell then probably shouldnt have an oil burner

I think if you take a min to look at what your putting in your truck you wont have a problem, most places now you have to push a button to get fuel so if you cant read then dont buy a diesel:U:

Lack of reading comprehension huh? :D

They are not mine

I'm gonna post some pics of a set of exhaust rockers and pivots that I just took off a CR truck. The customer had been warned over and over again, that with hard starts it's crucial that he watch the oil level and check for fuel in the oil. Now he swears there was never fuel in the oil, but for a truck with 60,000 miles, I'm not sure how this much damage occured. With that said, you CR guys keep a watch on your oil! This injector repair is now a pretty major repair. We're not sure what else has been damaged, and he only wants the rockers fixed.

To give an idea of what A repair like this runs:

$76.00 x 6 Exhaust Rockers
$75.00 x 6 Intake Rockers
$22.50 x 12 Pivots
$200.00 x 6 Injector Repair
$55.00 x 5 Labor
$20.00 Disposal and Shop Parts

So without tax this customer has taken a $1500.00 and in a matter of 30 Miles took the bill from $1500.00 to a $2600 + Job. Please keep a close eye on your oil! There's some test strip available that show if there's fuel dilution and the condition of the oil. They've been used for years with great success! We sell em for $6.50 a peice or 6 for $40.00. You can get them just about anywhere, its cheap security for a CR truck!

Where are the pics?

fuel in the oil can wipe out the crank bearings too. :ouch:

damn...........lil hot there :ouch:

I want to get some better pics to show exactly what I'm talking about, I took some but it dosent show the scores very well

:pca1:

Educate me please!!! How does fuel leak into the oil in a diesel from hard starts etc?

I'm going to do a write up, Schied should have my new rockers and pivots by thursday of next week , I should have the injectors from industrial by tuesday of next week.
When I get everything, I'll get a bunch of pics and do a nice write up talking about injector failure in the common rail and the effects of oil dilution. In this case, It looks like a cracked injector body, It also had 3 injectors leaking down. In this case, the truck is a factory truck so I'm not sure if he tried a box and busted the injector under high pressure or what the situation is. The injector is contained in a bore in the head, If the injector fails high pressure fuel is able to spray or leak into the oil system. With cracked bodys caused mainly from high pressure boxes you can actully make oil at an alarming rate, In a matter of 10 miles of hard running the engine can be destroyed!

PS , Or if the injector hangs due to poor lubrication you can melt a piston quick like as well!
