I currently have a 2011 Corsa SXI 1.4 Petrol sitting at 54000 miles. I recently purchased this about a month ago and had noticed that there is this mysterious ticking noise.
Startup No ticking sound at all while idle or driving for the first minute or so
While driving
After 1 minute of driving, the ticking noise occur Ticks only when at 1k-2k RPMs during slight or constant acceleration (no ticks when gas pedal is not pressed) Sound seems to be more noticeable inside the car compared to opening the bonnet Sound also occurs in neutral at 1k-2k RPMs Switching the Engine off
After a drive with ticking noises, turning the engine off and on again the ticks disappear and reappears after a minute of drive again. During the startup, there is no ticking noises whatsoever, however after a minute of driving the ticking noise appears and only ticks when I press the gas slightly and goes away when I don't press on it. I checked the oil, seems fine.
I took it to Halfords Autocentre & they told me it is likely it is loose pistons? surely if it was that they car would loose power etc.
The car runs smooth, starts smooth etc just the ticking noise is driving me mad
thanks!
