These are all good possibilities that the others have offered. So rather than be redundant, I would simply suggest the possibility that you may have excessive end play in your crankshaft. This would increase the likelihood of worn crankshaft bearings, allowing the connecting rods to put stress on the wrist pins, wearing them out.
It doesn't take much wear on the wrist pins to start getting piston knock.
As to the noise going away when you push the clutch in, you're taking the load off the engine by doing this , thereby reducing the load on the crank, allowing the parts to operate with less forces in them.
If this is the problem it will only get worse.
Good luck with this, hope you get it figured out

If it goes away when you do something then it isn't anything to do with the pistons or rods. If you press the clutch and it quits, the problem is probably with the clutch or transmission. Quite possibly the throw out bearing (part of the clutch). I have seen a stick get caught in the pressure plate (a part of the clutch) and as it spins around it whacks the inside making a knocking sound. I really doubt you will be that lucky, but you do need to have it checked out.

what's that in miles, mate?
t's engine time, the tappets are dry or the pisons are knocking, sounds like the oil ahs been low for some time. Get ready for the big bomb when it finally explodes.
If it's a clicking you hear it's just the injectors firing but if it's like someone at your front door it's time to shut her down.

i own a repair shop,and it sounds like it might have throw out bearing maybe trying to go out on it this would explain it not doing it when the clutch is in,if its that bad right now its going to get a lot worse on it,you need to take it and have it checked by a good mechanic and see what he says about it,good luck,i hope this help,s.

-broken bearing/piston (you're screwed)
-messed up timing (you're out a relatively low sum of money)
-some random chunk of something is stuck in there somewhere (could go either way)

has the timing belt been replaced? when it's worn it can hit the timing belt cover. but it could also be the lifters making noise

it could be carbon build up, try running some injector cleaner through it, the kind you plug into the fuel rail :)
