The francorchamps is letting me down again..

I'm having this weird knocking-sound from the engine itself in stationary (doesn't sound like a tapper to me)
And when I compare it to the rallye, it sounds really different! While they sound much more similar when revving.
(it's a 1.8 16v xu7jp4 on 10w40 half synth oil)

The knocking goes away when revving or driving though..

The local peugeot garage says it's OK, but it's just driving me mad and something tells me it's NOT OK...
I'm currently on 20mpg with this car, which can't be normal either (again, garages say it's fine..)

Here's a small vid with the sound (turn up your volume)
Knock-knock?

Any ideas?

Can you locate roughly where about in the engine bay the noise is coming from?

I would say check your mounts as it sounds like something hitting.

well, it seems like it's coming from above the cams or the inlet...

the mounts are still fine (just replaced one aswell)

i'll make a vid in daylight if that helps more!


*edit: i do seem to have a slightly higher than normal pressure in the inletmanifold

My car sounded like that when the power steering pump was shot.It (mine) sounded as if it was coming from the cam area though.
