    Puma 2.2 Fuel Rail Pressure?

    Puma 2.2 engine clatter is noticeably louder after 96,000km

    Hence seeking advice re fuel rail pressure...what should it be?

    at idle?
    at 100 kmhr / 2200rpm?

    I will set up my ultra gauge to read rail pressure and let you know what my 2.2 reads, later today

    At idle, low 20s.. I would be running some CRD cleaner/ lube through the tank, or even 200mls of non synthetic 2 stroke oil. Also worth a pilot relearn after 96k.

    Not sure what the specs are but this what UG reads from PCM

    3.5K psi at idle
    21K psi at 2200 rpm flat road 100kph

    31kpsi is about 22k Kpa

    Thanks JC, I will try some CRD. Hopefully that will do the trick as it sounds like my psi/kpa is about right. ...assuming 34-3500psi (approx 24000kpa) would be within normal operating spec at idle?

    Interesting that the 2 stroke mix comes into the equation again.

    I did it all the time with my D2 td5.

    It was originally considered not to add 2 stroke to the common rail engines and I'm very interested why the change of heart Justin.

    It did the td5 no harm over 100s of 1000s of kms.

    I would assume injector pressures in the td5 would be as high as the common rails?

    This was originally one the reasons not put any additives into your common rail diesel fuel.

    Any enlightenment would be much appreciated.
