Clicking-come-ticking noise from engine?
Discussion
Folks,
I'm sad to admit that my trusty Chim has largely lain dormant in the garage over winter, however I've decided it's a good idea to run her at least once a week whatever the weather - so to that end today I took her to work.
In the last few times I've driven her, and more noticeable than ever today, I've heard a [what's best described as] as ticking-come-clicking noise from the engine. As you've gathered I'm not of a technical bent but to me it sounds "tappety" - I don't even now if that's appropriate with these cars?? Could it be camshaft wear or associated kit??
The noise is more pronounced when the car is cold and when under load - however it's still there when just cruising and when she's fully warmed. It's also there when she's in neutral and you just rev her slightly. It definately sounds mechanically not right and I'm worried I'm making matters worse by continuing to drive the car. Anyone got any ideas as to what it might be? ....and more importantly what I should ask a specialist to look for and worst case scenario for cost?? ....incidentally I have checked the oil and she's 3/4's full (I'll top up once I can find some Mobil-1.)
Any ideas greatly appreciated????
Thanks as ever,
- Andy.

Exhaust manifold gasket. Happened to me last July - identical symptoms.
Have a look at this thread
Incidentally, it wasn't hugely expensive to fix. I had mine replaced with a high-spec steel gaskett and stainless steel bolts. Also had an MOT and had the power steering bypass pipe and clips replaced to repair a fluid leak, and the total bill came to £220.
See my car's profile for further details.

Hmm I wonder what sort of state your manifold is in? Similar symptoms could be caused by a split/hole in the manifold, or maybe the gasket?
Do read the thread I posted a link to though. As you'll see from an awful lot of people, the general concensus of opinion is to get it sorted ASAP or you run the risk of etching the head and that IS expensive.
Also, beware of doing the job yourself as a sheared bolt is a very real possibility and is apparantly a whole world of pain.

Quick update - just went out to the garage and stuck my head under the bonnet whilst the engine was running (sorry neighbours - boy that car's LOUD at 11.30!). Noise seems to be coming from one side of engine only, towards the rear. With my head under there it definately sounds more leaky-gasket than something under the rocker cover, plus, I could detect the whiff of exhaust fumes from that area. I'll leave it to the pro's but my money is on the leaky exhaust manifold gasket theory....
Thanks all again, aint Pistonheads great?!

Sounds like the exhaust manifold gasket to me. Sounds just like mine did.
You don't need to replace them in pairs, by the way. Just get the bank that is blowing done and then do the other side "as and when".
I had my N/S bank done back in July and the O/S bank is still fine. No point in spending out until you need to, as Dave Batty always says.

Just thought I'd update you on the "clicking come ticking" noise debate...
As so many of you correctly diagnosed, it was indeed a leaking exhaust manifold gasket - had it replaced by the chaps at the V8 centre in Wycombe and the car now seems like a different beast. Got that healthy V8 roar back, lots of pops on the overrun and seems to go like a rocket.
Thanks all for your help!
