thanks Louis just read your post after i posted. ill give those a look. glad you think she doesent sound too bad. i notice i dont spill as much coffee when the brake is depressed/lower idle.

P0236 = Check that the wastegate solenoid plug/wire/harness is not unplugged.....2 wires should have been for the A/C (as Buddy mentioned) and one of those plugs should go to the WG solenoid, if you are running the stock vacum setup and not a manual wastegate.

You mentioned that your SES light comes and goes......could be manual wastegate (Spring, instead of vacum) is set to high and you are running too much boost.

Get a pic of the turbo from the pass side and check to see if there is a spring there instead of vacum lines....
 
ive got a stock vacuum type waste gate and will soon install a turbo master i bought from Heath diesel.

that thermostat cord was good to go and plugged in.

the engine mounts felt solid. and what i could see of them looked good too.

Havent gotten into the crank pulley yet as im not sure how to inspect down there effectively.

there is white smoke at start up and at heavy acceleration.

thanks again Ian
 
White smoke is not a good sign. Your crazy vibration could be from major timing error or perhaps imbalances from coolant leak through head gaskets.
 
if i had a coolant leak there would be evidence in my oil, coolant level, and temp problems, i have non. ive heard white smoke is not a rare thing and mine is not constant or excessive. is that incorrect? should i have more DTC's poping up too? how would you recommend i trouble shoot this? ive never messed with timing is it simple of require special tools? thanks for the help Ian
 
White smoke on first startup is not uncommon, but not when you accelerate when warm. Water getting into cylinder wouldnt necessarily get in the oil and you likely couldnt tell if it was without analysis. It could take a while to get enough loss to cause a low coolant light. White smoke after warmup is caused by too advanced timing or coolant in the cylinder. If water were getting in then air would likely be getting in and pressurizing the cooling system, so if there were bubbles in the coolant that would show it, or if rad hose is hard on cold startup.

Still need to check the Harmonic Balancer, very important. Vibration is due to an imblance. That imbalance can be low compression in one or two cylinders. Bad injectors in a few cylinders, and bad balancer. With that much vibration I would think you would get an imbalance code.

I would find a scanner or software capable of reading the timing, the TDCO value specifially. Then run what is called the KOKO procedure to relearn the timing. And see what the value is after KOKO to see if it was not correct before. And it it goes out of tolerance and causes a code then it needs to be timed, by loosening injection pump and turning it. If you run into troubles trying to get the TDCO relearned without coding, or measured and desired injection timing is not lining up then there could be a mechanical timing issue with the chain. like a tooth or two off.

Slide under the truck and look for, Cracking, dry rot, broken, bulging rubber on the balancer....Same deal for the Crank Pully, and the crank pully has 4 bolts (one in each corner), make sure they look centered.....You'll understand this when you look at it.

Just make sure the "Rubber" on both are in good condition, thats the main thing.
 
i slide under to look at the mounts but there wasnt much to see the rubber wsnt sticking out but it felt good and the part i could get a light on looked solid.

ill get under there and after the crank pulley tomorrow.

the smoke has an eccence 'o' diesel but its not really dumping smoke during acceleration as much as i thought. maybe it was just my paraniod look back during an early cold morning mash on the throttle up my 20 degree hill. but that was after i realized the smoke from my truck was thick enough to be a tactical advantage if i were to attacked in my drive way after starting her cold 10 minutes before.
 
Thats not good... Does your upper rad hose get firm instantly on cold startup?

Next time the truck is warmed up and idling pop off the oil fill cover and see how much smoke (if any) is puffin out of there. FWIW This is a general blow-by test. Nothing to do with coolant test.
