Ok thanks Amba , will do my best to investigate it 

[feeutfo]

Frequency sounds to slow to be lifter, and it's not "tocky" enough either.

Sounds like exhaust to me. Manifold to head gasket? Or perhaps lower down.

I think i would sooner it be a gasket than taking the cams out , then again 

[feeutfo]

Maybe get Daz to have a look at it?

You might not wish for that if it is the N/S exhaust manifold gasket

That is a real bitch to do

  Suppose everything is do able with patience although i have read about some tough times trying to replace them .

Having heard your video mate don't think its a lifter.  Sounds more like exhaust manifold to me.

Does sound like it 

There should be a thin gasket that fits between the exhaust downpipe and manifold 

Do you mean the gasket to the bottom of the manifold Amba ? On the bottom of these ...

Doesn't seem to be a guide for exhaust manifold gasket replacements ..

Hmm. That does sound like a lifter to me. Pretty much how I remember the Silver Bullet when it suffered lifter issues. Sounds once-per-engine-cycle which would figure.

It's so hard to diagnose remotely, though. The noise sounds quite directional to me, as the camera is panned around. One idea might be to listen through a couple of foot of hose pipe to the ear. Run it round the cam cover and also around the exhaust manifold mounting to the block, from above and below. This really helps to identify the source of the noise. Is it only that bank that's noisy?

thats a bloody great idea!!!  that should isolate the noise.

kev, i spose the fact that its happening once every cycle it should narrow it down to one (or two) lifters per cylinder???

was thinking on the lines of compression stroke...? As opposed to cam revs. TB's being a combination of both with egr pipe on derivers bank and lifters... I thought?

It's certainly not the same noise as my old 3.2 when I got it. Far more aggressive and repetitive per rpm. ...could have been more than one lifter though I suppose.

But as you say, difficult remotely.

It is only that one side but seems more noisier further down the side . I been thinking that if some exhaust paste can be smudged around the bottom joint i could see if the noise goes away , not sure if a hand can be got up there to do that though .

Not hijacking.... simply trying to compare.

This is the ''ticking'' I have. Car hasn't been started for a day and it's about 8oC outside...... (ignore the slight belt squeal, I actually only noticed it tonight)



This is then after a drive when it's up to temp.....again bit of belt squeal but the ticking seems to have stopped.....



If I had to say.... I think this sounds like ''light'' lifter crud build up. Feel free to comment.
