ticking noise
 

Hi all,

05 blob 2.0 widetrack. 40k
Faint ticking noise can be heard at idle. nothing loud but its there. Can't really hear it from cold, but can hear after warm up.

Any ideas much appreciappreciated.
Thanks in advance.

Injectors can be heard ticking or could be a slight exhaust leak/uppipe.
Valve clearance,inlet manifold gasket etc..could be a number of things really.
Post up a vid/sound clip if you can.

See if you can locate where it's coming from as any noise needs investigation, if it's something breaking up then it will get worse but could be an easy repair at the moment,

If you use a laptop, cheapo desk microphone and headphones you can make a listening device. Idle the car until it makes the noise, point the microphone at different areas and hear where it's loudest. Worked a treat for me in the past.

I had two loose spark plugs cause a ticking/knocking noise,

Which was only there when warm

My classic did this. Noise was from front of engine.
Scoob garage removed the fan belt, it was still doing it.
Turned out to be the crankshaft pulley rubber anti-vibration layer had come apart, and the pulley was able to move.
New pulley.

Cheers for all the ideas here guys its really helpful. Gonna get proper onto it at weekend. Trying to upload sound but its not letting me. Probably this phone. Anyways my mechanic had a listen and he's asking me whether these models have hydraulic lifters? Cheers again guys this place is proper helpful.
