A ticking sound under load, any ideas?

[cleg]

I noticed last week when I took the Griffith out there was a ticking sound that was appearing to come from the back of the engine bay, from inside the cabin it sounds like its behind the centre of the dash.

The ticking sound matches the revs with regards speed of the ticking increases with more revs and only happens when the car is under load/accelerating.

I have been underneath today to check the exhaust but all looks ok, I also checked the manifold bolts incase gas was leaking past the gasket.

All this to no avail, has anyone else had a similar problem?

Or any ideas other places that could cause a noise like this?

Cheers,
Chris

Cheers Apache,
Pinking did cross my mind as I had to fill up on normal unleaded last time as they didn't sell super, but it’s not the kind of pinking sound I have heard on a car before.

It’s more of a tick that you hear if you actually say tic, tic, tic yourself quickly, if you know what I mean. (quick lock me up lol)

I will check the plenum just incase and fill her up with optimax ASAP.

Cheers Tim,
I did have a look the best I could when I was checking the bolts on the maifold, maybe its worth changing the gaskets just to be safe.
