Sounds like a diesel whilst ticking over!!!

[Fletch172]

Hi

I have a '52' plate 172 and recently the car has started to sound like a diesel whilst ticking over!!!!

I lift the bonnet and it sounds like the engine is racing! It only does it whilst ticking over, it stops once over 2000 rpm!

Anyone got any suggestions on what it can be and how to fix it??

Thanks

Could be a sticking hydraulic lifter , this fault would give the noise u decribe when did u last change the oil ?

 

[Dan@SJM]

do not drive it until you get it sorted.

its the cam dephaser, it'll soon let go and it'll be like the cambelt letting go.

did an oil change 6 months ago. ive ordered some hydraulic lifter treatment and will change the oil again. Hopefully this will help?

 

[Dan@SJM]

nope its not hydraulic lifters that are the problem as that would be through out the rev range.

nope its not hydraulic lifters that are the problem as that would be through out the rev range.

not nes as the oil pressure increase at higher revs could disguise it if the lifters only just starting to fail

Thanks for the feedback from everyone, looks like a trip to renault will be in order, maybe not to repair the car but to trade it in for a 197!!

Let me know how you get on Fletch172 as i've got the same issue with my 172 cup, sounds like a diesel and when you rev the sound goes. Getting the cambelt, aux belt etc done in 2 weeks, dunno if this will solve the problem.

I will do clip200bhp, thanks

checked spark plugs are tight?

 

[clio200bhp]

would that cause a knocking/ticking noise like a diesel if the sparks where loose?

As dan says it will be the dephaser, if its making this noise it won't be too long before it lets go and takes the valves/head with it. Stop using the car and get it changed. Its not a tappet.

 

[Josh@Renparts]

ive got a dephaser if you need one.

 

[Fletch172]

Hi joshydee, how much would you like for the dephaser?

 

[clio200bhp]

Does the dephaser get changed when you get the cambelt and aux belt kits put on. Only saying this as i'm getting the a new cambelt kit and aux kit put on in 2 weeks. Does anyone know if this will resolve the issue or get it replaced will the cambelts getting done etc?

 

[Dan@SJM]

nope. but if it needs changing the belt has to come off again so its effectively a new belt again.

 

[bmh.01]

And if its making that noise it might not last 2 weeks btw!

60 notes for the dephaser.
