Hello everyone,
On March 8th, a little less than a week ago, I pulled out my injectors due to getting some white-ish/gray-ish smoke coming out the tailpipe, at starting, for about 5 minutes in the morning. Once my rig warmed up, there was no white /gray smoke throughout the rest of the day, until the next morning. Based on everything I read and researched, it was likely a faulty/leaky injector.
I pulled all four, and noticed that two of the O-rings were broken (on #3 & #4 injector), and each of the holes (where the injectors are inserted into the top of the engine) were covered in black sludge (and #4's hole smelled really putrid).
Here is a photo of the #4 Injector Hole, right after pulling out the injector (with broken O-ring):
I cleaned all the holes up later, and they looked much better. Below is #4 Injector Hole after 1 cleaning cycle, and it still had the copper crush-washer in there:
I made sure to get that crush-washer out of the hole, and cleaned each injector hole 3-4 times. All the other Injectors still had the crush-washers on them when I pulled them out, only #4 left it inside at first.
I drove the injectors 2 hours away to the closest Bosch Diesel Injector cleaning/testing place in the area, Diamond Diesel in Oakland, CA. (

The technician said it would take 45 minutes to test each injector (and cost $80.00 per injector), and they were closing in 3 hours, so they would have to be finished tomorrow (Thursday) morning. They said they could call me Thursday morning with the results, and then ship them back to me that morning, and I'd get them by Friday morning. Long story short, I got the injectors back four days later. Here are the results and in the technician's words, which I really don't know how to interpret:
#1 Passed!
#2 Failed (VL off by 1/2 throttle, VE "Pilot")
#3 Failed (VL off by 1/2 throttle, VE "Pilot")
#4 Failed (VE "Pilot")
Here is a copy of their report:

Either-way, Monday night I put new O-rings on the injectors, new crush-washers on them, and installed them. I bled the air out of the hardline, started the rig after a few cranks... and the engine ran GREAT!
Maybe something will slowly get worse, but I don't want to wait to find out. Should I be worried?
Any and all recommendations are welcome.
Thanks,
Sarma.
