ticking whilst accelerating.

[amulday]

It's only started happening recently, when I put my foot on the accelerator theres this quiet ticking/creaking sound. I take my foot off and it stops. I can stay in gear and it doesn't tick, only when I'm accelerating.

Any ideas on what it could be?

coming from which area?

exhaust manifold gasket

how loud a tapping?
i would say exhaust leak (manifold/gasket)
or even maybe pinging if it is a light ticking from inside the engine.

Is it consistent or more varied?

if it comes from the lhs of the engine bay - while driving - and sounds like a soft inconsistent tikka-tikka noise - thats pinging and is very bad. You should get your AFR's checked immediately - and don't hold power while its doing it or you will see a piston more close up than you would like to....

After reading the posts I had a good listen, it sounds as though it is coming from the exhaust manifold. I'll take it in to get a new gasket and tightened up properly when I get back from work.

Thanks for the info

it may not be just the gasket. vr4's are prone to cracking exhaust manifolds.
