After cranking it to see how the install went, the oil started flowing again. I gave up... this was about 10 last night.
This morning I checked the oil level and there was nothing on the stick. So, I put some more in, let it idle for a while and got a temp gun out.
#4 cylinder got up to temp like the rest only a little slower. It also only had a 5 to 10 degree different in temp but then, so did #1 I'm guessing it was little slower to raise and stayed a little cooler because of the oil flowing through it.
The way it runs right now though, I find it hard to believe it's the piston. It really doesn't run that bad ( just a rough idle ) and I'm guessing if the piston was shot.... it'd be telling by more than oil coming out or not even be running.
I've gotten many opinions on this and I'd like to thank you 53 and everyone else who tried to help.
Right now my options are pulling #4 injector and using a scope or just pulling the head. There's definitely a problem and I'm going to change the injectors so, I might as well pull the head.
I did find out a new motor is cheaper than rebuilding one and the cost really isn't as bad as you might think. I'd prefer not to have to go that route though.

Sounds like at the very least you cracked some piston rings, how is the crank vent tube? more than the normal amount of oil dripping from it, or is there no blow by/oil coming from it? With the engine running hold a clean rag over the crank vent tube for a minute or so. Post what you find.

I changed and fill up the oil when I replaced the turbo. I ran the truck for a little while after the install and saw the oil starting to leak out of the exhaust again so I shut it down.
This morning I checked the oil again and it didn't show on the stick. Obviously, a lot of oil was being pumped right out into the exhaust.

based on this new info, I guess headgasket.....or something with the valves......
I don't have much experience with dropped valve seals on diesels but would oil in the exhaust ports be a sign of this?????? seem like it would??
any of you drop valve seal guys out there have symptoms like this???
I wish you would have fired it up with out the turbo and exhaust man on so you could seen if it was all the cylinders or just #4.......
I am no expert just trying to help.......

.And I do appreciate the help. I know you wanted to know how it did with the manifold off.
I did do that but, from what I know about motors, that's a for sure way to burn a valve.
It seemed fine when I cranked it with out the manifold. All 6 cylinders were firing and seem to have good compression. None smoked but, oil started to come out of #4.
I cleaned it out as good as i could, installed the manifold and turbo then started it again. The oil kept coming... this time in the exhaust.
My hopes aren't real high that it's nothing more than a HG or injector. I am putting feelers out for a new motor. Apparently, that would be cheaper than a rebuild.
If I do get a new one.... it's gonna be built to the hilt from the inside out. Maybe that will get me down the track a couple more times

I guarantee you wont burn a hole in your valve by running it with the manifold off for a few mins......
good luck with your problem
let us know what you find...
