ggggrrr!! I had a new Cambelt and runners fitted yesterday.  Ive just been out in the car and driven it for 9/10 miles, and its making a real ticking noise.  Its worse at lower speed than at higher speed.  Im assuming that the garage who fitted the new cam belt have done something to the car.  I has the cambelt fited because they said there was lots of play on the tensioners/runners.  I took the car in originally because I had the light appear - the one of a car with a spanner, thinking it was a cam sensor, bit its not!  Am I right that the ticking noise is connected to the new cambelt??

Update with model of car and did the garage who did the work use a full kit and locking tools?

[richard1967]

2002 2.2 petrol automatic, and yes they used a full kit.  Locking tools? DOnt know but have to assume yes

I would not run it again until it's been checked. Sounds like it could be valve to piston contact.

Can't see why it would tick :-/ something not right, what codes came up when they put it on a diagnostic?

Although may be irrelevant as you have a new proble, help will be along shortly

[richard1967]

Valve to piston contact? Youre not serious are you??? It wasnt making before the Cambelt was done?

[richard1967]

The codes that came up on the diagnostic, were low trottle response, service interface? and also they said that the ecu and gearbox control unit (its an auto) didnt appear to be talking to each other

That is of course 'worse case' if timing is out it isn't beyond the relms of possibility.

Where abouts are you?

[unlucky mark mv6]

I would take it back richard,if it aint right. :-/

[richard1967]

Hi Dave the Diver, Im in Swindon, Wiltshire............now youve got me really worried.  Surely if there was valve to pistion contact there would have been more noise.  This is a ticking noise that is worse at idle and low speed

[richard1967]

Hi Mark,  Yes Im taking it back tomorrow morning first thing

It's difficult to diagnose noises remotely and it could be something quite unrelated. However, if an engine starts to make unfamiliar noises immediately after a cam belt change I would always advise checking the timing straight away.

If the engine was not timed up correctly or the belt tension was not set correctly the timing could have slipped and the worst case scenario is that the pistons hit the valves.

I haven't heard this noise, so I don't know. It could be something trivial like a cover vibrating, but that's the worst case scenario, I'm afraid.

Spurious gearbox interface errors I have seen before, so if the fault wasn't marked as present I wouldn't worry about it. Throttle response errors point to a problem with the drive by wire system, so the throttle body or pedal position sensor perhaps. Would need to know the exact code reported to know for sure.

Was waterpump changed? Always worth changing waterpump when doing 2.2 cambelt

[richard1967]

Hi The Boy ( I got your message about reading the codes- thank you)
Ive just looked at the invoice, and the waterpump wasnt changed......sorry.  Ive just gone out to listen to it and it sounds like a diesel, not a petrol

[TheBoy]

If it didn't tick before, and does now, suspect what they have done.

What worries me, didn't they notice they introduced this noise (of course they did, but choose to ignore it), and I would have expected any decent garage to recomend the pump change at same time...
