VOLVO PENTA TAMD22 P-B

[Rog01929]

One other thought.

There is a small vacuum pipe which runs from the turbo to the top of the injection pump. This increases the amount of fuel sent to the injectors as the turbo gets going. If this is not connected at one end (I'm thinking maybe forgot to connect it at the turbo end), then you will not get the revs as the pump will not send enough fuel to the injectors.

Could it be that simple?

Hi
I have been trawling through various threads on the tamd 22 and lack of power and this is the first one that mentions this vacuum hose.Could you tell me where on the turbo array the connection is.I have a cracked plastic pipe connected to the top of the injection pump which I believed to be a vent/ pressure release.Is this the one you are meaning. Thanks for any assistance in this.

Check the heat exchanger for holes in the casing. My one had corroded away and was letting all the pressure from the turbo out. Also check that the exhaust elbow isn't blocked. Also check that the turbo wastegate valve isn't stuck open (you can do tis by removing the exhaust elbow).

I'm assuming that you've already checked fuel filters?

Hi, I have the same problem. My TAMD22 doesnt reach more 2000RPM (New turbo charger, Exhaust elbow ok, Fuel filter ok,). I have not enough air pressure to the inlet of injection pump to unlock the injection pump. I believe I have a problem on the heat exchanger... Please, could you tell me where was the leak on your exhanger? I am very interested. Thanks

Loss of power to my Volvo Penta tmd22 p-b diesel engine.. Turbo serviced. Do not know if it is valve or fuel injectors, not sure what to do next as I am not a mechanic. Any ideas. Drop off of power instant. Also black smoke. In neutral 4,000 plus, in gear between 2,000 and 2,200, had turbo reconditioned but not the problem. Fuel system checked all the way through fine. Re timed is good. Engine is very lumpy under power.

Hi, Did you find the problem? Thank you

You have to take it off and pressure test it. On trying to take mine apart, it was so corroded that it was not repairable, and a new heat exchanger was more than a complete new engine.

Good luck.
