All right, I don't know where to go from here. My truck is having some issues. I picked it up in Cali in August and drove it the 600 miles home, and it ran great, just a rough (and low) idle, and only made 8 lbs of boost. Once home I got a good look at it and the boost control solenoid was bypassed (it was bad), so I replaced it and took the KB chip it had out and replaced it with the stock memcal.
The idle got worse, to the point that it will die in Drive 50% of the time if I don't do the two step. It also has a serious off idle hesitation that no matter how much pedal pressure I use, floor it or barely lean into it, it goes no where for literally 2-3 seconds, turbo won't spool, tach doesn't move from 1000 RPM's or so, then all of a sudden it will lurch into boost and take off. Once into the revs it is smooth, but feels down on power (and getting progressively worse, so it's not just from removing the KB chip). The truck uses up coolant like crazy, but there is no external leak that I can find. I'm talking filling up the radiator from near bone dry every 10-15 miles or so of driving.
What I noticed today is that after letting it warm up, then driving a few miles there is a bad smell of coolant and steam/smoke will emanate from the air filter after I shut down the truck. Also the steam/smoke started coming through my passenger side defrost vent. There is also moisture in the air intake tube. This all makes me wonder if my turbo is crapped out, but it spins freely and has very little shaft play.
What has me really worried is that the oil looks like chocolate milk and is sticky on the dipstick, and the oil level is crazy high (full of coolant I guess). It just smells like oil though. No rod sticking out anywhere, old plugs looked normal when I changed them last week, and no coolant/oil mixture puked out any cylinder when plugs were removed, but who knows? Never had a bang or poof, no smoke from exhaust (hard to actually tell right now because it's 20 degrees out in the morning, so it's white coming out at idle, but no smoke while driving). I will drain the oil tomorrow to see what it looks like, I hope I don't find any metal.
So what's everyone think? Just turbo, or motor too?
Here is what I have done recently:
Cap/Rotor (MSD), Ignition module & coil (Pertronics flame thrower), Taylor plug wires, NGK UR5's gapped @ .032, PCV valves replaced, O2 sensor replaced (Bosch), fuel filter replaced. None of this made any difference, in fact it has less power. I also replaced all the vacuum lines with silicon except for the ones to the canister and vacuum ball (I ran out) and the check valves. It only makes 14-15 vacuum at idle, so I think I still have a leak somewhere.
No CEL. The truck has a AFPR, KB torque converter, KB cold air, KB underdrive pulley's. It had a KB chip in it when I got it, but I replaced it with the stock chip as soon as I got it home. The fuel injectors do not appear to be stock. They have a green top instead of red. The paperwork I received from the guy I bought the truck from had all the KB installation instructions and the Chip paperwork had instructions for both the regular KB "Streetmaster" chip and for one with 40lb injector programming for use with KB 40lb injectors, so I wonder if I may have those injectors. I have a set of low mile stock 32 lb injectors on the way, but haven't tried putting the KB chip back in to see if anything changes. I haven't checked idle FP because I don't have a test gauge, but I may go buy one tonight.
I guess the driveability/hesitation is secondary to the milky oil right now. So what does everyone think? Sorry for the long post, I like details.

. At this point your best bet is to stop driving the truck until you get a new mill in there. If you keep driving it, you risk SERIOUS damage that will make the rebuilt cost increase considerably...
