injector tap/click

[GregT]

Hi guys,

Recently got my 'scrap' terrano through the MOT and only had to actually buy shoes and wheel cylinders. couple of advisories but nothing bad. No corrosion or rust!

Anyway, it does have quite a tap to the engine. I checked valve gaps and they were to spec. Looking at the receipts it came with it had an engine rebuild in 2014 costing 2k!!

So I think it's an injector and the MOT man agrees with me. Are there any quick/cheap fixes? (or indeed time consuming cheap fixes) He said he could do it but wouldn't give me a price... never used a garage except for MOT's and at £70 an hour I don't think I want to start now. OR should I just leave it being a cheap truck?

As you probably guessed I don't want to spend much, I'm less than £500 into this and don't want to spend much more If I can help it.

Any help would be very much appreciated :thumb2

In my view can't see it being an injector ?

I am not sure how an injector can make a lot of noise though my experience is more with electronic ones rather than mechanical ones.

Have you used a listening tube to establish which cylinder the noise is coming from?

Is the noise at engine r.p.m or half crank speed - I am sure someone here will know more than me!

Have you tried a dose of injector cleaner straight into the air inlet?

If it is an injector making the noise then a broken/damaged spring is most likely, if you can positively identify which one, then it is a simple matter to replace it, you need to check if it is Bosch or Zexel, Rick
