I did a compression check, drivers side front to back (320,340,340,300 psi) Passenger side back to front (400,360,400,350psi) The dipstick is black with oil, when I removed the old CDR it was filled with grayish really thick oil. It doesn't seem to be consuming oil or coolant.

Did you re-time it after installing the new injectors?

Your timing is way off bud but the timing mark iis there to get you close enough to start so you can time the IP I bet your timing is a bit retatded
UPDATE: Finally pulled the motor and tore it down....was hoping to just replace head gaskets and throw some studs in. Found a crack in the #4 cylinder wall....the head gasket actually looked pretty good. So now i am in a debacle where I have quite a few new parts for a 6.9 idi, but cant find a 6.9 engine. There are a lot of 7.3's out there. Anyone ever get a reman long block???

How bad is the crack, could you sleeve the cylinder and fix it.
Problem is i cant find a reasonably priced machine shop local to me....I spoke with the 3 nearby (Philadelphia area) 2 didnt want to touch it and 1 said it would most likely be over $1000 just to bore .010" over. I called CDI and Mel has a block thats in good shape he is willing to part with. Hopefully Thursday afternoon I will be picking it up and starting to put it together this weekend. Anyone recommend a good machine shop that would sleeve my current 6.9? Wouldn't be opposed to slowly building up a turbo engine to swap out later.
Cleaned and rebuilt the block from Mel and got the truck back up and running. Found a turbo 7.3 idi with full turbo kit (turbo needed rebuilt) for cheap so i picked that up and sent the turbo out to GPOP shop for rebuild/upgrade. Truck is back together, inspected and on the road. Currently looking for a zf5 to swap in and put the turbo kit on. When i rebuilt the 6.9 i put head studs in so should be good with the turbo - not looking to blow smoke just make some more power.

For that bubbling injector, I have had that happen. You may check to see if you have the copper washer missing. I see one of them is in the picture.
