It's a double row timing chain on my 1.8.
The tapping sound seems to come and go.
When it comes, it is more apparent at higher revs (2000rpm) and seems to fade away as the revs go down.
It sounds faster and slightly louder when the accelerator is pushed.
Could it be drivetrain related, coz the tapping is not there when I rev in P.
It is only there when in Drive.
