What A Failed Injector Looks Like

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!

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!
