My dephaser pulley has been noisey for a fair few months now but there's another noise that's quite worrying. It only happens when the engine is warm and when the throttle is blipped at low RPM. Could it still be related to the dephaser pulley or has another issue developed. You'll have to forgive the quality of the video as it was taken with my phone.

Depasher pulley?

In that video yours isn't making the same noise as mine, (I've watched that video quite a few times to see if I could hear it lol)
As the revs die down on mine I get a crunching sort of noise.

Just been out to it again and tried it. Yeah it does it as you've explained, rev it and you get a single crunch noise, then when you let off the throttle and let the revs drop it does it again.
Does sound like what you've explained though, funny how I've never noticed it before. Thanks Jord.

In your video, is it pointing out the high pitched whurring sound that it's doing when the word "noise" pops up in red?
Edit: Just heard the exact same noise in your video, panic over! Lol.

Much of a job to replace? Cost of the parts? Mine has been like this for some time, too lazy and tight to replace it :rasp:
nope if the car comes in sounding normal it "should" be fine, but if it starts rattling 6months down the line its not my issue, its the customers choice, if its a high miler i advise it
if it arrives sounding like a diesel = new dephaser
if the customer requests it - great, that would be the ideal thing to chage every dephaser on every cambelt change, unfortunatley the part is just over £140, so not everyone wants to spend it
unfortunatley there is no way to tell when a dephaser is going to start rattling, i advise RS clios should have an oil and filter every 6K, looked after that way and the dephaser will be fine, its due to lack of oil changes IMO they start rattling

What do you mean solenoid? is it easy to change,
i have a slight noise in my engine and still trying to find the fault, at first thought it was dephaser but its new,
Yep dead right mate. It's a pulley which is fed by oil pressure to advance and r****d the timing on the inlet cam hence the term vvt for variable valve timing, fred is also right, they are not changed when the cambelt is changed unless they are noisey or the customer complains, the most common time for the noise to be heard is on first start up in the morning when cold, there will be a clatter but it normally goes away quite quick when the pulley first starts to play up.
As for the valve, they have been known to make silly noises, sometimes you can be lucky and give them a "tactical tap" as my rte told me and this will sort it for a while or for aslong as it fancies really, might save you a few pennies
i disagree with you there, they never make a noise when cold its when the oil gets upto temp and thins out they start rattling
Mine is fine from cold, soon as its warm, it rattles its tits off

too much cold engine abuse?

From what I've heard, yours is suppose to sound just like mine. Don't know what it is of late but a lot of people seem to be having dephaser issues recently.
this is true, i'm just going off my experiences, only because when i've checked the reference values for the solenoid valve the percentages have been correct, otherwise the noise is the valve holding the oil way either open or shut i'm not sure and causing a surge/starve of oil to the pulley

That's good enough for me then Freddy boy
I've got an engine for you sir btw - excuse my thread hijack

anything i get
the most common time for the noise to be heard is on first start up in the morning when cold, there will be a clatter but it normally goes away quite quick when the pulley first starts to play up.
on the 1.6 16v K4M engine , the dephaser will rattle when first started , and dissapear after about 5 secs , unless proper knackered.
the 1.8 16v F4P and 2.0 16v F4R tend to rattle when hot , and be fine first thing.
As fred has said though , regular (quality ) oil and filter changes can help the dephasers live longer , but i have done a couple that are serviced with quality oil and filter changers approx 5-6 k miles and have still failed ,
1 started failing just before a cam belt change due , the other started failing approx 5k after the belts change. dont figure ?:S
customer paid for the bits and i fitted it all for free as she is such a good and long standing customer.
Bit of a funny noise coming from my engine bay at the min. Haven't located 100% yet, but have been reading about dephasers. I realise these are usually changed with cam and aux belt kits, but my car isn't due any belts...
So, how much am I looking at for a replacement dephaser fitted? Am I looking at around £350, 200ish labour, 150 part???
Also Reading this understand that become noisier when oil is warmed through and thinner, but does noise lessen at all with fresh oil?? I'm guessing that damage is done?
Hopefully this isn't my issue, but doing some digging
