Expert's Assistant chatimg
Customer: Hi Bob
My 2011 1.4 petrol Fiesta (zetec auto) engine has a very noticeable tapping sound (at half engine speed) which to me sounds like tappets although I've been told it is the injector. The sound is most noticeable at idle or at low driving speeds. The engine feels a little sticky ie not very free revving. I would appreciate knowing what it is (and if it can be treated). Thanks, David

Hi is it David good evening to you and sorry for the delayed response

Ok does the vehicle have a lumpy unstable idle

Does the vehicle missfire or hesitate on acceleration

Is is the tapping noise worse when cold

Kind regards ***** *****


the idle is not lumpy and there is no misfire; the engine feels otherwise sound. The tapping is noticeable at start up but if anything is more noticeable when warm. under the bonnet I can hear a clicking sound around the injector (which I believe is normal) but there appears to be a tapping (rattle) around the camshaft area. At above 20 mph the sound is not noticeable - I notice it because I drive a lot in queues in traffic.The oil level is near the top dipstick mark. The mileage is 25000.

Hi there good morning to you and sorry for the delayed response

Ok this tapping noise is commonly just an injector noise

We see a lot of the 1.25&1.4 zetecs booked in for a noise from engine

we compare the customers car to a brand knew one and found the tapping noise to be from the injector solenoid

I have had a handful of vehicles where by the valve clearances have needed adjusted due to a rattle from camshaft area but this was on earlier zetecs ie2006-2008 models

I haven't seen or heard of anyone adjusting later models valve clearances for a noise

If you require the measurements to check the clearances I can provide them for you but in my experience(obviously I cannot road test the vehicle ) it will be the injector solenoids (this is normal for model )(design intent )

If you need anymore help or advice on issue please let me know

If you have been completely satisfied with my answer /advice


Kind regards ***** ***** and have a nice day
