    Fiesta 1.4 TDCI Engine noise

    Hello all,

    Take a listen here -

    [youtube:14eh23ed]http://www.youtube.com/watch?v=f9iR_-vW_uc[/youtube:14eh23ed]

    Sure, you can hear the engine running, but what's the cause of the additional rattle?

    I'm wondering if I have a hydraulic valve tappet that's failing?

    Will post again once diagnosed and repaired as it may help others.

    Thanks
    Richard

    I'll be honest... I can't hear anything other than the engine running :-S

    I'm sure I can hear something, it does sound like it's only from one pot too.


    Is there any other 1.4 owners on here willing to do a similar clip to compare it with?

    I can deffo hear it
    Might be one noisy injector?
    You could try unplugging the injectors in turn and see if the noise goes. Try it at your own risk though as I've heard the injector can remain open and try and flood that cylinder with diesel! (I have unplugged the injectors on my old Fiesta with no probs though)

    Thanks TMagnet, will try that.

    It's in bits just now. I'm replacing the cam belt. The jobs going fairly well so I should have it mobile again tomorrow morning. I was wondering what state the cam belt was in (89,000 miles) and maybe it had stretched. The belt that's come off looks in pretty good condition so it will be interesting to listen to it tomorrow to see if there's any change.

    I'd check the injectors for leaking exhaust gasses...

    DON'T UNPLUG THE INJECTORS ON A RUNNING ENGINE!

    the engine will start just fine on 3 good injectors so switch off between unplugging. if you have a siemens ecu you likely have piezo injectors which indeed stay open until the ecu closes them.
    cubic inches, there's no substitute...

    I'm pretty sure this is a leaking injector, it seems this is a common problem with 1.4 tdci Fiesta cars.

    Symptoms are:
    - Chuff chuff rattling noise from one pot as per the video
    - Have removed the air cleaner, there's lots of backed on oily carbon deposit around one injector
    - Have seen blue smoke appearing from under the air cleaner
    - Stronger than normal smell of oil under bonnet.

    Will post again once repaired.

    there is a very strong possibility it is an injector seal.

    It's fixed!!! Problem was a leaking injector seal on the second cylinder. Thanks to all those who posted.

    Cost of Injector seals, 16. 1.5 days of DIY labour at a steady pace. Lots of time taken cleaning components and the cylinder head.

    Some pics for your interest...

    Not pretty....
