TD5 Injector Spring Broken

[Budley]

Hi Team,
I had to change an injector on my TD5 Disco, which had broken the return spring and spat out the little injector push-rod thingy.
My question is - What can cause an injector spring to break?

I'd had the tappet cover off a few days earlier, to clean the injector harness plugs (usual symptoms - rough idle, low on power). When re-assembled, everything was fine. Idle and power back to normal.

I'm concerned that something I've done was the cause of the injector failure - re-fitting the tappet cover, or not seating a plug properly, or something. But I can't imagine anything that could cause a heavy duty spring to break like that.

Any ideas?

Don't worry i have seen a few also. These high tensile materials can have tiny imperfections and flaws which can manifest themselves a long way down the road as breakages. The instances are very rare to be fair and it certainly is not caused by anything you may have done. Jc

Thanks Justinc,
That's reassuring.

Cheers,
