Rattly injectors

[Mr Whippy]

There is a thread over on theywhoshallnotbenamed and some people are saying reducing the advance of the pre-injection removes the ticking noise a bit, since later cars have reduced pre-injection advance.

However, I'd want to do a test before/after to confirm it using some actual recording equipment etc... not just go on what I thought it sounded like had changed.

I'm also cautious about just changing maps to alter a noise without knowing WHY the later cars had it adjusted, and why the early ones had it the way they did.


Lastly, all the HDi's I've seen have ticked to some extent or another. I don't really notice it or care about it. These engines run to 200k without issues even on original pumps/injectors if looked after, so something must be right

Recon injectors will probably reduce the volume of the ticking, but chances are if they have over 60k miles on them then recon injectors will do the engine the world of good in lots of other ways too any way which is the better reason for fixing them any way



PS, will someone send me a PM, just so I can check the forum sends me an email?

Thanks
