wierd ticking noise constantly coming from fuel rail?

[sebstenator]

i notice wen i turn my car on and listen into the engine it has a constant ticking noise. i tried to hear where it was coming from and it seems as tho its coming from both sides of the fuel rail. would anyone know what the problem could be?

[Boonz]

how loud is it? could be a lifter?

could be an injector?

its more often a lifter than an injector. still possible though.

It is common for injectors to tick as they pulse.

EDIT: put a screwdriver on the injectors, if the tick is in-time with any of them when you touch it, then you'll know.

hmm well its not the injectors cos they dont tick that loud but yeh it cood possibly be the lifters not too sure tho

[vn calais manual]

narrow your search down with a mechanics stethoscope or as said a screwdriver. if its a lifter, then just try some lifter free up, every now and then u get the odd car this stuff works on. but more than likely youll just have to live with it untill your ready to pull them out.

reckon its a lifter deos it go away when it runs a bit

More than likley its the injectors especially on a V8,i had a VR statesman V8 and the injector pulses were very noticable,wasnt lifters.But if you had a lifter noise you would know about it,a lifter noise is more a higher pitch than an injector pulse.
