    Default Advice needed with low powered Ford Ranger 2.2

    Hi all. I have a Ford Ranger 2.2 T6. We have replaced the injector seals on the valve cover as well as the valve cover gasket as it had a small oil, since then it seems as if the bakkie doesn't have power. Slow acceleration, poor open road performance and poor diesel consumption. Seems like it's also using oil. It doesn't smoke only on cold start.
    No codes are given on diagnostics. Injectors are fitted in the correct order.
    What can be the problem?

    Can you compare your engine bay with someone else's.

    It might show you something that was installed incorrectly.
    Check that all electrical plugs are clean inside and fitted correctly.

    Air box/ intercooler hoses tight?

    It does seem like all the hoses are connected tightly. But I will have a look at the plugs. Thank you.

    Sounds like a damaged or unplugged sensor, unfortunately you'd need a code scanner to check the errors.

    Is the check engine light on? If the vehicle is in limp mode, the light must be on.

    There were no error codes when the scanner was plugged in. There are also no lights on, no engine light and no traction control light.

    Can this be faulty injectors perhaps?
    I can't detect any leaks on the down pipe or the boost pipe.
    That's why this is so confusing.

    Any big issue will have a code.

    If a sensor sends a rubbish value, the CPU doesn't see it as a "fault" to throw an error code.
    We had that a while ago on my daughter's diesel Micra. The temp reading that was sent to the CPU was -273°C (0 kelvin). The motor was performing horribly, while trying to compensate for the absolute temp it was trying to cope with. At first Nissan said it was turbo problems. Turbo guys found low compression and said motor was gone. And all the time no error code. Lots of subsequent testing found the -273°C reading. Replacing the sensor didn't help, so finally Nissan said CPU must be replaced for R10k. In the end we disconnected the plug from the airbox sensor. That gave an error code, but the car ran perfectly.
    So Jelo, I actually support your earlier suggestion that a sensor is faulty, but it doesn't necessarily have to be accompanied by an error code.
    The statement by the OP that the engine is suddenly using oil is very confusing though.

    Sounds like a boost issue that can also come from an enrichment issue. You need fuel to spin up the turbo. If there is a shortage of fuel, reduced boost..
    Could also be a leak of boost. A little sensing pipe can make all the difference. Make sure all the little pipes have a home.

    Had this with a 2.5 Navara after some work was done.

    I had another look and there are no pipes out of place and there are no pipes leaking.
    I will have to take it in, hopefully it's not something major.

    Thanks for all the advise.

    The wastegate on the turbo not stuck?
    CAT not blocked?
    EGR blocked off?
    Musn't the intake manifold be cleaned out?
