What exactly did you do to the injectors?

Can you provide any more history of the noise? When did it start, or did you buy the car with the noise?

Generally the lifters are noisy at idle, but then quiet down at higher RPM, so I doubt this is a lifter.

It could be a problem with a delivery valve or two on the injection pump, or a deeper problem in the injection pump, or an internal problem (bearings) on the engine.

Can you make a Youtube video of the noise, and post the link?
