Rattling noise - from engine bay

[Nismo_286]

Hi guys,

would anybody have experienced rattling noises from their engine bay?

I am driving a R32 and this rattling noise seems to be coming from the throttle body. The sound comes and goes and the worst part is, it sometimes whirrs when I am accelerating.

It is similar to this problem as quoted :

and i quote:

"I am experiencing a weird tapping noise that appears to be related to the engine speed and temperature. When the bonnet is down, you can hear it pretty clearly just by standing behind the front wheel. With the bonnet up, it's drowned out by the engine noise / injector clicking. It goes away eventually when the engine's warm. It's louder while idling."

What is the cause of such a problem? Is it the lifters or throttle body?

Anybody knows how to clean lifters and throttle body? Or recommend any good workshops that can do it?

Many thanks to you guys. I totally appreciate it. Any advice and info would be helpful.

i would say most likely a missing bolt from your exhaust manifold......coz mine was missing like 3 of em when i got it fixed up....u will need a new manifold gasket as well in the process.....coz mine only did then when the car was cold and dissipated as the engine heated up

I was told by a mechanic at Nissan, that the noise I am experiencing are from the injector solenoids and clutch plate.

He mentioned that as the noise that i am experiencing is rather random as such, I do not have to worry about it. But if it starts to become noisy constantly, it can be from the lifters which might need replacement.

Hope this helps.

Cheers.
