2.5DI fuel pump/smoke adjust

[andypdq]

Just a thought here and I don't even know if this is possible but if the torque sleeve sticks the syptoms are normally the opposite of the symptoms you are experiencing.
Could the torque sleeve stick at the other end of its travel thus giving great pull but smoke and poor fuel economy?

Correct, if the piston sticks fully open it will overfuel at low rpm, good power, lots of smoke, poor fuel economy.

Worth checking then, here's the 'how to' link

Thanks i check that! Maybe i need new gaskets before i open it?


My fuel consumption is not totally bad. It was 8 and under at highway with first adjust and it runned pretty well.


Then i got creedy and adjusted more. It started to smoke some, not awfully. Consumption rised about 1liters 100km.

Now it wont stop smoking no matter how i adjust. Runs fine. A

Check, maybe the air damper on your car does not open fully?
There will be a lot of black or gray smoke and fuel consumption will increase.
It is difficult to search for a malfunction in someone else's car on the Internet with the help of a google translator!

Is there some part numbers for torque sleeve/seals?

[Ransettimies]

Part number for whole torque sleeve/piston?

Uh... Still fighting with too high fuel mileage

No matter how i turn screws i only got: good power and speed with pretty fair or very fair amount of smoke or very little smoke but poor acceleration and top speed.

Now fuel economy is 10-12liters / 100km and before it was 8 liters / 100km.
