Right guys...rather than try and explain my engine noises i thought i would try put on a video.....please click on the link below
The engine was up to temp
Tick over on 700-800 rpm.
think the ticking is the fuel injectors but its the knocking that is the worry, it doesnt go up with revs well cant hear it, and is louder when the engine is warm.
..it has had a good oil change, full spec oil synthetic, air filters etc,

Any ideas from your wealth of knowledge or is this terminal
