Ticking noise from inlet, not tappets.

28th July 2011, 23:58

another thread about my ticking noise....basically i have a tapping/ticking noise which sounds like the tappets but it is only when the engine is warm, doesn't do it until the engine has warmed up.

The noise isn't all that noticable although i can hear it....if im driving in a quiet road and in like revs higher than ticker if im not accelerating i can hear it....it cant really be heard at idle its just when the engine is revved and it gets quicker with revs.

The things i have tried are:

-tappets adjusted to spec...plus two mechanics have said the tappets are fine and the noise isn't coming from them.
-spark plugs are tight.
-changed the ICV as thats the only thing i thought it could be in the inlet mani.
-just had the injectors cleaned by injectortune.

Does anybody know what it could be? I havent really seen another vtr to look but i have seen a few peugeots with 1.1 8v engines and they dont seem to make the noise?

nobody?

29th July 2011, 12:04

could just be the injectors, they naturally tick

29th July 2011, 12:15

it mite just be you thinking you hearing it when really it isnt that bad at all

Possibly an air leak on a vacuum hose,that`s all I can think of mate.

You may be right, but its defo noticable like i say in a built up area...moreso than other cars

How would I check for this mate? Cheers for the suggestion.

Get some washing up liquid & smear it around where the hoses join,then run the car if there`s a leak then you`ll get a bubble.It`s what gas engineers used to do when checking for leaks on pipes.

Okay mate thanks, i'll try that tomorrow, got a feeling it won't be that though as it just sounds like a rattling ticking type noise...a bit like tappets but its coming from around the inlet area....i hear the leaks are more like pop noises? :/ I may just have to live with it.

tbh honest mate i`m clutching at straws because I can`t think what else it can be.

The injectors are noisy even if they are clean they will still be noisey.

I can't understand it myself....have stripped the throttle body down to see if there was anything loose there, but polished it to a mirror shine while i was at it so wasn't all a waste of time lol.

Really? Are they louder than say a 1.1 peugeot 206 as I believe they are a variant of the TU engine and the guys i listened to isn't as loud as mine.
Its funny you should say that, when I fitted a spare set of injectors to send mine away, i thought they seemed ever so slightly quieter than my set but thought it must have been my mind playing tricks.

I just can't imagine the car coming out of the factory with this noise...which is why i thought it wouldn't be injectors if they are doing it when clean? For example its not as loud as say those tappy fords and corsas you hear....but can be heard if the bonnet is close and you give the engine a rev...

+1 Agreed

30th July 2011, 18:42

Even if the injectors have been cleaned the internal parts are still the same so the old muck and grime in them may have actually been insulating the injectors

30th July 2011, 19:46

been said but i read the whole thread so im still gonna say it

noisey injectors will be noisey when cleaned or not, it can only really be injectors or tappets

the tappets may be worn, and hence noisey even when set

30th July 2011, 22:50

cleaning injectors will not cure worn injectors, the ticking noise the OP refers to is common on these engines as previously stated and a new/replacement set of injectors is needed

Like I say though mate it doesn't appear to be coming from the rocker cover, its coming from behind there, ive set the tappets at both 0.2 0.4 when cold and 0.2 0.3 when warm and although i thought there was a difference it appears there isn't really....i have also adjusted them using the thread pitch and its pretty mutch the same as setting them with the feeler gauge.

Ah shite....so i've pretty much wasted my money cleaning them? I read a post of yours which i prosume i've confused cleaning with refurbing? I couldn't imagine either the injectors or tappets being nackered after 60k miles though?

If so how much does refurbing cost and do you know where I can get it done?

A quick update on the noise if this will help, basically i can hear the injectors quietly on idle....which sounds different to the noise im trying to combat, this noise is more of a rattle sound...kinda like someones thrown a ball bearing or two in the throttle body or a loose bolt and when revving it rattles...the noise only seems to appear if i rev above approx 1750 rpm though, and like i say it only seems to appear once warm... please someone help me sort this as its doing my head in, hope i haven't wasted £50 cleaning my injectors though :/

31st July 2011, 19:39

also, does this faulty injector noise sound like tappets..as thats what mine sounds like but its not from that area.

1st August 2011, 00:04

Anyone? Heard a saxo tonight as my mate drove past him and it did have the same ticking sound....not sure if mines louder though?

2nd August 2011, 00:16

I took the car to an engine reconditioners today and they did say they could hear a slight rattle but would be happy if it were theres as its one of the quietest of these engines they've heard...and another lad there said "whats up with it it sounds sweet to me" lol but yet the noise is still noticable to me. They did get the stephoscope on it and the only thing he could point out was that no.2 injector sounded "louder and harsher" than the rest through the stephoscope and said I should swap no.2 out with my spare...if that doesn't sort it swap them all out for my spares. I swapped the one today and it didn't appear to make such a difference so i shall try swapping the rest out tomorrow.

If not i dunno what it could be....i know they said it sounds okay to them buti know for afact it wouldn't have come out the factory with this noise and i want it gone lol.

2nd August 2011, 00:32

i honestly think your mind is playing tricks on you now you know it's there, seems it is being exaggerated as you have noticed it.

maybe get a video up of the noise? gunna check mine tomorrow to see if it taps ha.

2nd August 2011, 16:49

think ive got the same noise- got used to it on mine as its a 10year old car- and oviously has worn abit over time- been told by a mechanic its my injectors

I think you might be right mate, it was the fact i can hear it in built up areas making me think its loud...i have now swapped to my spare injectors despite spending £46 getting the others cleaned....so we'll see how it goes.
If anyone wants to buy a set of clean with new filters and seals and perfectly flowing(yet maybe slightly noisey) injectors let me know.

Ah thats probably it mate, I might get a quote on some brand spankers if my OCD mind can't live with it lmao.

I have a vts, and I've changed the clutch in January, but after that I've detected a leak in the gearbox and I've took it back .. and after that I've started to hear a kind of a tappet noise but not so strong, in acceleration and deceleration, but only when the car it's hot .. I'm tired of spending money and nobody knows what it is, saying that it's normal .. but the car never made that sound ..
The clutch is a valeo original citroen.
The flywheel was also taken out when I changed the clutch, to replace the crankshaft seal .. but only at the second time that I took the gearbox out, the noise appeared..

24th September 2011, 01:21

Could that be the clutch bearing I dunno? I hear its a common thing on these?

Mine was the injectors it seems, had my set ultrasound/ultrasonically cleaned and the noise was the same if not louder...so I swapped them for a spare set I had from a scrappy and the noise seems to be gone, or a lot quieter...waste of money cleaning the injectors but if anyone wants a slightly noisey set running a decent flow rate let me know, must have covered under 50 miles since cleaning haha.

Maybe is the clucth bearing, but when I press the clutch the noise is still there..I´ll try to took the gear box out again..it´s the only thing I didn´t try again..

Sorry I can't be of more help mate, maybe worth making your own topic to get more views from somebody in the know?

P.s- sorry for my English..

25th September 2011, 02:15

No probs mate, you can continue if you wish as i've sorted the problem

I just thought you'd get a few more views if the title described your problem more

Hi. Iam new to this forum. I had this ticking/tapping noise when engine was warm only. I could hear it was from behind rocker cover and was told various things it could be. Injectors. Inlet. Even tappets lol. It ended up being a lose spark plug. Took coil pack off. Tightened the offending plug and tapping gone.

fingers crossed now.
