hi, this video shows the knocking sound that my Land Rover 2.25 diesel has. I am pretty sure its a diesel knock from an injector, however I don't know wether it could be bottom end? or even a hot spot? anyone know what this is? I am leaning towards a bad injector because when cold it likes to miss and puff smoke on one cylinder.
any help appreciated,

thanks.

Series 3 - Land Rover series 3 knock

hi, I have a series 3 2.25 diesel that has a slight miss when cold and a constant knocking sound. when started cold, the engine seems to be missing or poorly firing on one cylinder. it sends a shake through the cabin and a puff of smoke from the exhaust. after about a minute this stops. however...

Did you check the heater plugs and test by slacking off injector nuts

It would be better if the vid was under bonnet , what happened when you slacked off each injector nut in turn when it’s running

I will get a video from inside the bonnet later. when I slackened off the injectors it wouldn't stay running, and would stall.
 
When I did mine when I had diesel knock when you slackened the faulty one it still ran whereas on the good ones. It stalled. I also disconnected suspect injector swung the pipe round so you could see spray pattern and it was more like a single jet than a spray

Slackened them one at a time rather than all together?

It should still run, albeit not well, with only one injector slackened at a time.
