Can anyone tell me why my Landcruiser has no power under 2000rpm.. no smoke from motor or turbo, turbo spinning freely, airfilter is clean, injectors are in excellent condition. At revs and driving its got full power! super smooth at idle, starts and runs perfect except this low power part, to the point when if I put the ramps under the front wheels it wont go up enven these without a run up. It seems to have gotten worse over the last few hours of driving. would love any help anyone can give! :)

well it runs,,,,,
low power on a diesel is
1: low compression
2: bad fueling
#2 can take forever to find, if you dont know what engine it is or what fuel system was used.. no country stated, so cant guess
read the wiki on land cruiser and see what you have.
we dont know.
Its getting oil in the cylinders from somewhere. With it being more smokey in the morning leeds me to think its valve stem seals ( oil lying on top of the cylinder head around the valves) . Could the new engine have been old stock. If so then the stem seals probably hardened. They may soften with running a while. If it is under warranty take it back now.
Those old engines were made to last - compare the weight of the motor to one of similar capacity nowadays; the old ones were made of cast iron which is quite heavy, the newer ones like the C270CDi Mercedes motor weighs about 30-40%less due to aluminium parts. Longevity suffers, but you need less power to drive the engine, giving you more power to drive the car. Furthermore, the common rail injection used nowadays are a lot more flexible and powerful, due to the fact that the exact amount of diesel needed per cylinder stroke is injected, whereas the old system injected a fixed amount per stroke, whether you are doing 20mph or 80mph. So, it overfuels at low revs and underfuels at higher revs. To prevent it from burning too lean the engine has a rev limit, roughly where the mixture is running at "100%" effectivity. The newer motors use computers to make the decisions based on 83452 different inputs, the older ones just measured the diesel needed and the air supplied.
So, the sad news is that the only way to get the car to perform a lot better is to put in a new moter eg. C270CDi, or put in a REAL motor like a 350Chevy :-D but leave the 300D badge on and see the other guys $h@ their pants when this "diesel" smokes them!
The 100 series td is boost limited for 1st gear , this was a factory design to stop consumers getting overexcited at the traffic lights etc! If you think you are getting no power or boost in first (which would be odd) then connect a boost gauge to the turbo pressure vsv (vacum switching valve) on the intake manifold to see what sort of pressure you are getting.
All this can get a little bit involved ie type of motor 1hdt,1hd-fte etc etc, repost if you need further.
escudo 2.0 V6, the idle is ok and the rpm quite ok, but smoke is so heavy when start in the morning, it dosent run smooth. can you help me to, i already change the spark plug but same stoyr, any solution?
