300 tdi white smoke and loss of power

hi guys, got a problem with my 300 tdi 1997.
I was driving across a field 20mph and the engine note changed and power seem to die a bit, coming home on the road it was more noticeable.
started the car this morning and tickover was normal but pulling away was a real struggle and white smoke. as the engine warmed up things got a bit better, when you rev the engine to a certain rev band the smoke appears and it starts to misfire.
I have checked valves and gaps and cracked the injectors with the engine note changing on all four, could it be turbo as when I removed the inlet pipe it was making a slight wurring noise..
thanks in advance.

Slipped timing belt perhaps? When was the timing belt last done and how many miles has it done?

Head gasket gone ?

Isnt coolant white when "combusted" ?

smoke from exhaust is ie steam if it disperses instantly if it hangs around its unburnt fuel

belt was done 3 yrs ago and tickover is sweet 137000 on the clock.
head gasket doubt it, oil clean no white deposits and no pressure in header tank.
this is smoke not steam.
like I say, it runs smooth until you hit a rev band and smoke appears and it misfires.

Had a similar experience and it turned out to be turbo gone,

cheers chris, that is what I was suspecting. I can smell the oil burning as im going along, but im going to do a compression test the weekend to make sure cylinders are good.

remove out let pipe from turbo and run engine see if oil seeps out , run engine with intercooler to inlet manifold hose off, check all valves fully open and tappets as well as compression test

thanks james, will do.

strange thing, started it this morning and performed as normal with not much smoke. weired..

mine did this,
turned out to be water in fuel filter, (only had the car a few days),
changed fuel filter, perfect since,
neil

I have the same problem on start up white smoke but it clears after about 1 mile I did my
Head gasket 3 weeks ago and I know oil went down exhaust mines a 300tdi auto and I've lost power when boost gauge gets to 0.8 to 1 reving about 2100rmp I get white smoke that hangs about see it in mirror but turbo makeing a nose like the impeller is hitting a playing card I'm changeing my turbo for one of a mate n fitting new exhaust this week also checking all inter cooler hoses for holes n oil also cleaning turbo oil feed n return hose will post if any better after parts fitted

thanks for the info lads...
