I can put you in touch with a quality injection/ HD truck tech , that can come to you and get  you up and running .  Call me and I'll shoot  his #.    The transit  will be 500 or so .
 I trust him completely and he works for me when  his racing overlaps mine .  He has keys to my shop .
Thank you, as soon as we get the injectors back and I have it running again we may do that.  I don't want to have anyone show up until we're at least back to where we started.

If I was able to get a leak down tester wouldn't I still need to find the correct adapter to fit in the hole for our specific injector?  It can't be a universal piece can it?
Leak down testers come with a variety of adapters.  If you'll find out thread dia and pitch I'll check my kit.  If the proper adapter is there I'll be happy to loan my kit to you.  Only ask you return it when done.  Can't be a bad thing to know condition of rings, valves and seats, head gasket and compression on each cyl.  Like others say it won't test valve guides but you can eliminate a lot of variables. (But Protech's reference to a top shelf mechanic is probably the best way to go if you can swing it )

Thank you, Chuck! I will see what I can find but I don't believe our injectors have any type of thread on them.  The adapter should look like an injector and it will be held in place by the retainers.

Diesel Adapter M17 Injector - Cummins Case C Series

Found this but the problem is that I don't know what injectors we have.  This is for the Bosch M17 injector but that might not be what we need.

The compression tester with all the adapters posted earlier can probably be used with the leak down tester. Several of the adapters were for Cummins. You could just pull the compression quick connect and snap on the leak down quick connect and do both at almost the same time.

Did you ever check your delivery pressure from the secondary filter to the injection pump? Probably one of the first things to do.
Easy gauge installation with only a "T" needed. This eliminates low fuel pressure possibilities. Need remote gauge or camera for full load readings. This is my idle pressure.

The mechanic did check the fuel pressure and said it was good but the engine wasn't under load.

  Called the mechanic today. No answer. so I drive to his shop and spoke with him.  He said he'd been in PA for training since Wednesday and that he'd have them tested and let me know tonight.  No call.  Have a feeling that tomorrow won't produce a call either.  Hopefully we're wrong. 

  Found the problem with the generator, the radiator is plugged full of junk.  It was getting too hot, overflowing coolant everywhere and shutting itself off. And also the exhaust is broken in half at the manifold and filling the compartment and probably the cabin with exhaust.

  We made some room on the engine  by removing the two useless ac compressors that were sitting in the way of everything.  There was no refrigerant in the system and it was all filled with rust, and one of the lines were already broken so we just cut the other ones and got it all out of the way.

  We're supposed to be in PA this weekend to see family but I don't think that's going to happen. 

  I don't know if this is typical of coach ownership or full-timing but this has been an insane past 6 months.  I'm addicted though.  There's nothing like a good old fashioned trial-by-fire haha!

I was wrong, thankfully.  The mechanic called this morning and said all of our injectors tested good and that he'd be down this afternoon to get it all back together. He is going to bring his timing kit and double check the timing on the injection pump.  Hopefully we'll have a better idea by tonight what's going on.

One of the compressors circulates (or did) the refrigerant in the basement unit.  The system was designed so that the basement ac could be operated via the engine compressor and the inverter could power the fans.  That way the generator was not required to operate the ac while driving.  The lines to the basement unit were disconnected years ago.

I'd really rather just pay him for his time, get our parts back and put the hole charade behind us.  I can understand something coming up and having to postpone but it's aggravating when someone says they're going to do something and then they don't.  It's really aggravating when they don't have the decency to call and say they can't make it. Oh well.

I did take some time and today to adjust the valve lash so the day wasn't a total loss.

Were any valves real loose or tight?

They were all good.  I only adjusted three and that was more to just try it than anything They probably would have been fine but now that I've done it, it's not intimidating.

I'm rethinking my opinion about the turbo not being the culprit.  There was a faint but very oil-like substance around the area where the gasket was allowing exhaust to escape.  I took the turbo off to have a look and one bank of the exhaust inlet was lightly damp and had an oil smell to it.  I guess I don't understand how it would be causing the smoke and the residue in the head without leaving a large trail of oil.

We're about seven hours from Turbo Exchange and if they can do a warranty tear down on it Thursday I'll probably drive down and have them do it. 

I'm anxious to find out if we made a wise decision on going with the cheap turbo or if the $1700 genuine Holset from Cummins was really the better deal.

Have rebuilt hundreds of larger turbos,all brands including Holset my point being a brand new one will last longer then a rebuilt,in
my opinion of course.99% of them had an oil related problem,carboned up oil passages,that's probably one reason I use synthetic
oil.

C'mon down!.  I have a pair of Honda V-4 motorcycle engines.  You can adjust the valves in those, and, once done, you'll be good to tackle anything.

What we know.
The oil would need to go through the engine to foul the exhaust ports.
White smoke is unburned oil.
Diesel fuel is turned into a fine white fog by the fuel injector.
The engine starts and runs normally.

Now we can make an educated guess.
Raw engine oil leaking past the oil seals in the turbo follows the intake air.
The oil boils and becomes a cool vapor in the cylinder and is exhausted, unburnt.

Part of that was my reasoning for faulty exhaust valve seals and or loose valve guides. Oil would flow down the exhaust valve stems, boil in the exhaust gases and emerge as a white, unburnt, vapor.

If your turbo is leaking enough to create the white smoke, you've been a very lucky man so far.  Just as you can run a diesel engine on starting ether, you can run a diesel engine on lubricating oil from a leaking turbo-supercharger.  The only way to save an engine when this happens is to use a board to close off the intake air, because you have a positive feedback loop.  More air. more oil, more exhaust.

I have never seen a runaway except it the Detroits. The ones I worked on had the lever to block air at the blower. Not saying it couldn't happen, just never experienced it as heavy equipment mechanic.
