|OhFOURpointFive||Oh I will! Business has been slow so i couldn't afford all 6 at once but over the next several weeks I'll be replacing the remaining 5 as I can afford it. I will say I have never done a compression on a diesel before. I'll have to see if my snap-on dealer has the test kit. I'm sure there are multiple kits considering each diesel is unique in a way especially a ctd since I'm assuming you have to test compression through the injector hole.|

Run a compression test on #6.
Watch for signs of the other 5 going didi mau like a hawk. White smoke is the kiss of death in these.

|OhFOURpointFive||Just an update. I got the rail plug in and just as I thought, #6 is the culprit. Capped the rail on #6 port and smoking stopped. DPPI is sending a driver with my injector to me now as I am typing this. Will have the truck running by this afternoon!|

welcome to cumminsforum...
go here and grab a manual to help as needed with your truck. (did not read the whole thread to see if it was mentioned or not)

That's really weird. I wonder how diesel got over to that side of the engine onto the manifold. Was there any fuel on the bottom of the hood?

Do the key on three times code tests, reads out in odometer window. Displays DONE when last code is displayed.
Write down and post.
Pull an oil sample and send in to oil test lab for analysis diesel contamination in the oil.
Run a compression test and post results.
Post up all numbers on each injector.
Most likely leaking injector nozzle pintle/s, leak raw liquid diesel into cylinder 360d of rotation. One blockoff fitting is not enough to find multiple leakers.
Soak the injector nozzle ends in MEK or acetone overnight if you can't locate the leaker. Try injectors.
Do you smell raw diesel while cranking motor, injectors in?
You've stepped into the modern world of HPCR diesels, expensive. Be ready for parts price shock.
Cheap parts in these kill engines.
Once you have white smoke problem solved, these MUST had HD commercial fuel water separator and dirt filters. OEM factory tiny insufficient ineffective filter is an engine killing POS. Lubricity fuel additive 100% of the time.
What engine mods?

|A.C.||I just had a similar issue and I bought the 20$ test cap and went down the line (starting with #1 since it's the easiest) and sure enough, when I capped #6 the knock and smoke went away. I bought this truck non-running, so I don't know how long it was leaking, but it was bad enough to cause carbon buildup in the cylinder increasing the compression to 600 PSI (all other cylinders @ 460-480). I ended up ordering all new injectors from injectors direct, but that was more due to the other unknowns on this truck and wanting to start fresh. When I talked to their tech support about the cost of testing the injectors, it just didn't make any sense for me to go that route, it was 50$ to test each one, and I think 100$ to clean them if they were good, which ended up being just a little more than a reconditioned one. To save as much $ as possible, I would buy the cap, identify the bad injector, replace it with a reconditioned one from a reputable source and reuse the rail lines and the injector tubes. The injector tubes are supposed to be one time use, but it sounds like you already have 3 injectors out, and I have heard of lots of guys reusing them multiple times (usually increasing the TQ on the retaining nut slightly to ensure a good seal). Good luck, and let us know what route you end up taking and how it works out.|
