172 ticking

[Avo-R]

please please please can anyone help??

seem to have tapping noise on idle which is more noticable when your inside the car, it doesn't always happen but worried what the problem maybe.

any ideas???:dapprove:

it will most likely be a relay clicking!

 

[Avo-R]

na mate its well coming from the engine cause if i rev it its gone but seconds later back

aux belt and tensioners possibly?

 

[mij29]

Hydrolic tapets or the injection, used to get it on my GTE16v

Had this on my 172, needed the aux belt and tensioners needed changing.... £600 at Renault... :-( they changed the cam belt also..

 

[Avo-R]

umm maybe it is.. just hope it dont cost the earth my bro has a clio and said something about charcoal fuel box on the side of the engine

I had a very tappety sound from my fezzy, but that was couse i hadnt shimmed the engine proper after putting fast road cams in.

dont think thats what yours is

most likely the charcoal canister, they are metal on 172's but the 182 has a plastic un and they don't tend to do this.

If it ticks constant at idle and you rev it the tickin increases its the charcoal canister!!
Nothin to worry about, i think there £40 from ReNo and its located left side of the engine.

Take left wheel off - remove the plactic and you'll see a box thing!!

I haven't bovered with mine!!

All good tho!

what the hell is a charcoal canister?

 

[Justin182]

Yep, it the Charcoal Canister as mentioned above... i think its cause by there not being sufficient lining round it or something and is nothing to worry about. If you rev a little, it should increase and then go away.

It is used to evaporate exhaust fumes i think.

 

[philmots]

think mine does this too, new aux belt and tensioners go on in 3k anyway!

 

[pip.]

Mines done this from new, usually does it when the engine has been run a while, but goes away when revved.
I simply view it as part of the Clio percussion

 

[Avo-R]

just happy its nothing bad its defo this charcoal cannister from what u guys are sayin...

 

[LegoHead]

that's funny, how can you say for certain it is the charcoal cannister.lol.

 

[JONNY172]

ahhhh, so its the noise from the switch/relay that opens and closes the tank feed on the charcoal cannister!!!

that makes sense!

had this problem on my subaru so i removed the whole system!

what the system does is allow the fumes from the tank to be burned at idle so there is no vent to atmos on the fuel tank.
