watermeade Posted January 31, 2007 Posted January 31, 2007 Hi, Can I ask if any members with a 1.6 petrol consider their engines to be noisy please. On a cold morning my sounds not unlike a diesel,I am guessing it is the hydraulic tappets pumping up,but it takes a good 5 - 10 mins fo the noise to reduce and even then if I drive with the stereo off I can hear a constant ticking,is this normal or have I got a problem ? i.e are these engines noisy or have I got a cam/tappet/spring problem. TIA... Quote
wozza Posted January 31, 2007 Posted January 31, 2007 Cant say there typically noisy engines no. Mines near enough silent to be honest. Quote
Rich_Eason Posted January 31, 2007 Posted January 31, 2007 Engines with Hydraulic tappets will always sound rattly on start up more so on cold mornings where its be standing over night. This is normally down to small amounts of oil draining off, nothing serious as once the engine is cranking ti builds up the oil pressure again. The ticking sound you refer to, is it comming from down near the drivers door pillar? Some owners have reported on here that the depolutions canister(which is located in this area) make a bit of a clatter, not too dissimilar to that of the tappets. Most of us here have experienced it at one point or another. If you are still not convinced, my suggestion will be to drop it in to the dealer and get them to look at it and see what they say. Hope this helps. Quote

My 1.4 is noisey on startup - but the noise reduces after a few minutes - it tends to help that I usually send the gf out to warm the car up before most journeys :blink: The ticking sound you refer to, is it comming from down near the drivers door pillar?

Is there a fix for this? I noticed the noise this morning - was definately coming from the driver side pillar - particularly so when the driver door was open and engine running. Quote

Havent seen any fixes yet that cure it......but then apart from the fact you can hear it, its not a fault. Quote

Havent seen any fixes yet that cure it......but then apart from the fact you can hear it, its not a fault. I had this, the dealer confirmed what kfk said, not a fault, but did take it out to look at it, they said they didn't do anything to it, but on the way home I noticed it had gone, never to return. That was 9 months but not many miles ago. Mine was there all the time, never disappeared, but you could only notice it really when stationary. Other than that super quiet! Quote
watermeade Posted January 31, 2007 Author Posted January 31, 2007 Thanks for the replies Guys, Much appreciated... Quote
Guest CE05LDB Posted February 1, 2007 Posted February 1, 2007 My C3 1.6i 16v Sensodrive is quiet. I find my brothers is a bit louder and when changing gear in his. Quote
Welshguy Posted February 1, 2007 Posted February 1, 2007 your noise is caused by the charcoal canister electrovalve.........i would be more worried if it didnt do it. Fair enough - thanks again for inparting your knowledge! :D Can I ask....what the hell does it do? :unsure: Quote
Stuey Posted February 1, 2007 Posted February 1, 2007 Can I ask....what the hell does it do? :unsure: The question I dare not ask :D Quote
syrup Posted February 1, 2007 Posted February 1, 2007 Fair enough - thanks again for inparting your knowledge! :D Can I ask....what the hell does it do? :unsure: This was supplied by kfk in an earlier posting on this "basically.....as simple as possible....... fuel tanks nowadays are sealed and not allowed to vent to atmosphere.....hydrocarbons being bad for the atmosphere etc..........so how do they allow the tank to vent and get rid of the hydrocarbons (vapour)? They fit a charcoal canister under the wing and a pipe runs from the fuel tank to the canister......the canister then has a pipe that connects to the inlet manifold. At a predetermined time the canister valve will open and close....the speed of its opening and closing is determined by many factors. when it opens it vents the hydrocarbons into the inlet manifold where they can be burnt.....the clickng noise you here is the valve opening and closing, it sounds like a single tappet loose."

bill03 Posted February 1, 2007 Posted February 1, 2007 And I always thought it was the Doppler compensators being out of phase with the warp matrix flux capacitors. Should have known. :unsure: :D Quote

I have exactly the same noise have you got anywhere with it?.I have been to two dealers who pronounce there is no fault...im not convinced....sounds like premature wear taking place to me Quote

Welshguy Posted May 7, 2007 Posted May 7, 2007 <_< Your not convinced it's the cannister valve then as previously stated? Not sure if this is entirely relevant but the noise from the cannister value has completely gone after my 20k service... Quote
watermeade Posted May 11, 2007 Author Posted May 11, 2007 I have exactly the same noise have you got anywhere with it?.I have been to two dealers who pronounce there is no fault...im not convinced....sounds like premature wear taking place to me I have noticed that it is very temperature sensitive,below a certain temperature it sounds like a Diesel ,nigh on all day,but on a warm day like yesterday which was around 15 degrees it was noisy on initial start up but this decreased after a few miles until it was barely audible,but around 10 degrees it is very noisy most of the time,so I have concluded it is due to the oil viscosity and decided to stop worrying about it.Also I have complained (on here) about the ride being hard,and I have noticed I get a (marginally) better ride on a warm day.I was wondering if the fluid (or gas) in the shockers may be more fluid when warm and this would account for it.Any thoughts ...

Is it from inside the car you are saying it's noisy? Quote

watermeade Posted May 12, 2007 Author Posted May 12, 2007 Is it from inside the car you are saying it's noisy? Oh yes,funnily enough it sounds worse inside the car,from outside it seems quite quiet,even in a multi storey car park where you would expect the sound to be amplified due to the reverb.Today it has been 15 degrees and apart from the initial startup noise it has been been nearly silent,and is coming from the camshaft area,if I lift off the throttle it goes quiet but put a bit of throttle on and it comes back.As I said I am certain that it can be put down to the oil viscosity/ambient temerature and have decided to stop worrying about it.

Had a good listen to mine today for you (1.6 petrol) ultra silent even on start up in my garage, when stationary I sometimes have to check the rev counter thinking I've stalled it. As I've said previously the only noise I had was the cannister valve which Welshguy has got back ;). No problem with the ride either, but it probably depends on what you were driving before, mine was a Freelander. Quote

No problem with the ride either, but it probably depends on what you were driving before, mine was a Freelander. To be honest I think mine would be quiet if it was kept in a garage overnight,as I suspect the ambient temperature would be higher.Unfortunately I have more chance of becoming Pope than getting my car in due to all the CR4P in there ...Now where`s me Mitre gone...

Re:Ride. I had a Laguna before this and compared to that,Driving the C4 over anything but a nigh on perfect road is akin to driving over a ploughed field (no I am not kidding) I suspect you could drive over a fag paper and feel it,but on the Motorway it is an ok ride,but over manholes or slight depressions it makes me just that....depressed..
