Starts and runs smooth, throttle up. runs rough and it puffs white smoke. Pulled all plugs, no water, doubt it is a head gasket. Could not get timing to set, way high before smooth idle. Replace timing chain, not get timing set to 10 btc, and runs rough. No check engine light, at a loss, no clue, and suggestions?

Have you checked youre water level? White smoke can indicate water. May be headgasket. I would also dble check valv clearances and timing for tge rough running. 180° out of timing may be the rough running too.Just go through top to bottom your work. could be wires not in correct position.
white smoke mostly is caused by over fueling so what i suggest you do is first of all check if there is no leak on the injectors and if there is none which means your valve sterm seals are damaged.When the head gasket is blown out you may have problems like :-loosing power when driving,over heating,idling problems and oil mixing with water, its not your head gasket.
Sounds like either a blown motor (rings need replaced) or a bad head gasket or cracked head. If the rings are bad your car would have felt like it was losing power because the engine will no longer have the same high compression that it's required to turn the wheels. You may have heard your engine knocking or seen a light blue colored smoke coming from your exhaust as a result of your engine burning up oil in the combustion chamber from the rings leaking. If your head gasket is leaking or your head is cracked you'd likely find milky looking oil when you drain your oil from water/antifreeze being mixed in and noticed a white smoke coming from your exhaust that is actually water vapor coming through the exhaust. If your car was running rough when you last shut it off try pulling all of your spark plugs and either cleaning them or replacing them all. A bad head gasket or bad rings can both foul spark plugs. A car will run rough with 1 or 2 fouled plugs, but once enough foul it will no longer run at all just sit and crank over. If changing the plugs get's it started for ya, check your tailpipe first for water, if nothing, change your oil. If no signs of water/antifreeze or milky colored oil then it's probably rings.
White smoke is a sign of water/condensation (due to the coolant additive)......worst case scenario, you have a head gasket leak (minor at this stage), or you simply need a tune up......as white smoke on cold start up could be normal...has it just started happening, or have you only just started noticing it ???
When was the last time it has been serviced (plugs, oil etc)
Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
If your intake gaskets are leaking, when you dump soapy water on the gasket, it should bubble like crazy ( when it's running). If you can, run it with the rad cap off and watch for bubbles. If it keeps bubbling, you probably have a head gasket problem.
