I've got this strange noise that occurs at low RPM, like below 1000RPM if I'm a little fast off the clutch and the revs drop I get this knocking noise coming from the engine bay. It actually sounds as if the engine is bumping against something. I've looked and I can't see any contact being made, or the engine moving around more than usual on the mounts.
I thought that it might be a bad engine mount, any other thoughts?

Re: Strange noise at low RPM
Yes it may be getting pinging/detonation due to being under too much load. Try putting the car in 4th gear, drop to 40 km/hr and then try to accelerate, it may do it then also. Like a metallic 'rattling' sound. If the timing has been advanced and there is 91 octane petrol in the tank, it may be pinging/detonating and require 95 or 98 octane petrol. Easy thing to check first.

Re: Strange noise at low RPM
It could be the Hydraulic lifters.
Have you lifted the bonnet and played with the accelerator and listened for the noise?
