Hey guys.. having a night mare with my astra j vxr.
Wondering if anybody has any ideas.
Its got a loud whine sound once warm from top left side of engine bay but only on idle or very low rpms. Checked belt pulley tensioner and its not that.
Don't wanna replace timing chain as everyone's saying as it sounds nothing like a chain issue.
No power loss/ problems at all, still drives perfectly Other than ridiculous loud idle. Sound like a bus when warm
Has it had any work on the water pump?
I offer a chain fitting service on this series of engine also if required :)
Are there any codes ?
