2001 f250 tapping noise

[thew1ld]

Can anyone help me I have a 2001 f250 that has started a tapping noise it sounds like a gas motor out of time it does it when it warms up its on the drivers side I had #8 injector replaced it failed the contribution test but passed the buzz test . would low fuel pressure cause noise only on one side of the motor? Thanks

exhaust leak could cause it too.

It could just be injector crackle....which is normal for the 7.3L
