Location of data plate (with ESN) on my C8.3 - if you have the B5.9 it may be in the same place:

Standing at the back, looking at engine.  See the air conditioning compressor - directly below that is a flat sheet metal engine cover with the "oil fill" hole in the middle. At the top right corner of this cover, on the edge, you'll see the black engine data plate.  The fuel injection pump is directly behind it.

Once you have the ESN, you might like to visit Cummins QuickServe.com and Cummins Parts.com.  You can register your engine for free, and find a wealth of valuable data pertaining to your specific engine.  This is the exact same info the high paid Cummins techs see on their shop computer.

I know that my 5.9's engine serial number is on a sticker on the timing gear cover and underneath the alternator bracket.  I also know that I have a rear mounted radiator and charge air cooler.

But thanks for showing me how easy it is to see yours.  Maybe someday I'll show you mine.

I have the Allison numbers, created an account then needed an hour of frustration to realize I need java script.

It's raining very well here in southern Georgia.  The prediction is for 5-6 inches of rainfall today.

Injection pump timing was spot on with engine TDC.  I don't know what else to do.  I found a mechanic to come and look at it today.  I feel like a failure :(
Trying to solve this problem, you have worked harder and done much more on your own than most of us would.

When the solution to a particularly thorny problem eludes you, asking for help is not weakness - it is a sign of intelligence.

Most modern  drives are not prone to jumping timing .  They may sag a few degrees due to system wear.
 Did you ever do the balance test?  Did you pull the injectors and look for pintle/valve failure.?

I did not do a balance test.  I was really focused on the timing and became too overwhelmed to confidently attempt anything else.  My abilities are not what I had hoped they would be.

Looks like you have the old mechanical style pump/injector system . Simply fire it up, set the idle up a little  to maybe 1000RPM.  and loosen each injector, measure the RPM drop .  Let each hole skip for 30 seconds  and see which hole/skip reduces the smoke , if any.

 Keep a rag around the pump to collect the fuel that will run out and a fire bottle.

When I pulled the exhaust manifold, five of the six exhaust ports on the head  had a sticky oily residue on the inside.  Could all of the injectors have went bad at the same time?

But your abilities are getting better all the time!  Are you lucky enough to have a fuel injection service shop near you?  I was thinking of something like this one in New Hampshire.  Diesel's Fuel Injection Service Bow NH | Injector Testing, Repair

That sticky black oil makes me suspect the exhaust valve guides are allowing oil to get by.  That's the next simplest problem.  Does the engine start easily?

The engine starts and idles good. The smoke started all of a sudden so I don't know.  Hopefully the mechanic will give us the answer.

The mechanic just left and what a super nice guy! We tested the fuel pressure and it was good.  Had to remove some intercooler piping and the two air conditioner compressors on the engine to get to the injectors.  Pulled all the injectors (one did not want to come out) and did a compression check on all of the cylinders.  Each cylinder had around 400 psi, the Book say 300 and up is good.    No clear answers presented themselves but he took the injectors with him to flow check them at the shop.  Should know by tonight or tomorrow morning what he finds out.  It was really cool getting to work along side him, I learned a lot and had a really good time too!

If this happened all of a sudden the turbo should be suspect. White smoke, blue smoke sometimes hard to tell apart.

What we have not solved (and I agree with the dreaded 'blue smoke'), is 'are you eating oil for breakfast'? If it's the seals, there will be no noise, just blue smoke and oil consumption, big time. At higher altitudes, the color will change to white; LOTSA WHITE!

The smoke is definitely coming from the engine, the turbo is no longer suspect.  I don't know what it is but I know it's not the turbo.

Never had my injectors out but now would be the time,if you can stick a dowel or something thru the injector hole and touch the top
of the piston you can find TDC once and for all and mark the balancer,it will either be on the compression or exhaust stroke.If on compression you adjust ex valves 1,3,5 and intake 1,2,4 turn it 360 degrees and do the rest.Not sure what you meant by "dropping
a valve"that is a mechanics term when a valve breaks and causes engine damage.

I made a timing reference with a piece of solid strand wire. One end was attached to a bolt on  the front of the engine and the other I bent to point at the harmonic balancer. I used the lash adjustment to force the exhaust valve open, then Hannah slowly rotated the engine  clockwise with the barring tool and ratchet until the piston bumped into the valve.  I marked the harmonic balancer at the wire reference mark. I then adjusted the valve closed, had Hannah rotate the engine until the piston was past TDC and on it's way down.  Then adjust the valve back down and rotate the engine counterclockwise until it bumps the valve again.  Make another mark on the balancer.  Since the engine is actually at TDC for a few degrees the two marks were about 1 1/4 inches apart.  Split the difference between the two Mark's and that is exact TDC.

Would just make sure all the valves are adjusted correctly.

I really wanted too while the valve cover was off but had too many things on my mind to add one more.  Still would like to take a swing at it though!
