My toyota 3C turbo diesel engine the turbo compressor is flooding of oil . I can.t trace where it is coming from That is why I am searching service manual for this turbo charger. 12ct

Question edited for clarity and spelling.
Question moved to model category.

Some ideas in the link. A Pro Grade scan tool computer could record what happens when it warms up.

..

no year car told nor miles on it. 1990 to 2019, no country told.
2.2L oil burner.
a Previa variant car. 1990 -1999 wiki said
"The Estima Emina and Estima Lucida were also available with a 2.2-liter diesel engine (3C-T and 3C-TE)" w/and ,w/o intercooler.
so you forgot to say full engine name is/was a Turbo and if is
that , does it only overheat on BOOST>?

there is no answer to that, should I questions (but yes)
many engine (means toss coin) STAT pulled cause turbulence to the pump and now the pump impeller messes up and flow decreases.
and if not the temperature runs way too cool 150f is common.hot idle.
180 to 200F is normal.(STAT in place) your auto part store will tell you.
now the list of overheat causes.

1: the cooling system is failing, (alarge list)
clogged radiator,
pump impeller blades rusted to nothing or 1/2 way.
some one forgot to burp the loop of all air. and RAD level cold is way way too low of AF , anti freeze coolant.

2: using water only and not 50% antifreeze,never just water.
3: fans dead rear oif RAD.
4: fan shroud lost. (other owners bad acts)
5: old cars with fan thermal clutch the clutch is bad.
6: fan belt slips at fan or pump. or both, (year car told)
7:old hoses (big) bad and collapsing inside. hidden.
8: side RAD overflow bottle missing or bad or hoses inside and outside missing so every day you run the engine coolant is lost to the ground,.
9: bad head gasket engine burns coolant or far worse engine cracks
10 head in engine cracked, or just warped.
I-4 engines have no valley gasket so it is not leaking V6/v8
11: and coolant lost to ground,front passenger foot wells
12: coolant lands in Oil pan ,oil looks like milk chocolate.
i'm sure missed, 5+ more points of leak failures. sure.

Check spark , as a first step.On anything...
then check fuel reaching engine intake , injector feed rail etc..

actually, 3c...is that a diesel? I remember LiteAce 1c CM20 used to be a diesel...if so, cancel what I said about checking spark..

It seems you haven't been taking enough care on your car up to the point the whole cylinder head is worn out leaking oil from the inlet means both the valve stamp seals,valveguides ,oil scrapper rings valves and timing belt worn out. The timing jumped making the piston hit the valves damaging the guides and seals, oil started to come into cylinder and during comp%ssion it is pushed through the valves to the inlet until it damanges the throttle body.the D4 pump is also faulty, low pressure if the car can't rev. Better do cylinder head service and buy another D4 pump before condemning the throttlebody

As long as you install everything required to run the diesel yes.

It sounds like the turbo has gone out. That will make a diesel sluggish and burn oil out the turbo. replace the turbo and it should be fine

It is part of the cause,

why their is a back pressure in water system what is the cause,when you accelerate ,the accelerator.he water comes out on the radiator filling valve?

Clean intercooler.Full of engine oil

If it has glow plugs or an intake heater you will need to disable the circuit. Then you can use a small amount of ether to spray into the air cleaner.!!! If you spray too much and/or Dont disable the circuits you can damage the motor!!! When you spray the ether, if the engine starts and stalls then its not getting fuel. This could be related to the fuel pump, injection pump, the fuel system loosing its prime(fuel line leak), fuel shut-off valve or solenoid. If it doesn't start then it could be related to your timing, valves or maybe compression.
