V6 wierd noise from manifold

[VN_Pretz]

hey guys,

was playin with the VY the other day and noticed a sound comin from the manifold once the ignition is turned off, sounds like a ticking noise, lasts for about 3-5 seconds

any ideas?

thanks in advance for your help

are you sure it's from the manifold? There shouldn't be anything moving in the engine 3-5 seconds after it's turned off.

My car makes a ticking/squeeking noise for 3-5 seconds after i turn it off - but I think it's the radiator fan. There's no odd noises when the car is running so i haven't really looked into it.

this would be expansion/contraction noises coming from the steel when steel heats up it expands and when i cools it contracts and makes a ticking noise (like a house with an iron roof in summer) i know my z does the same this i just thought this was the case also could be the thermo fan as old mate said

okay cool thanks guys, i didnt think much of it as it's been there a while and not distinct while the cars running

hey guys, just established that it does it without actually starting the car, so it's not the fan, thinking it's still intake

probably the IAC on the throttlebody moving to its preset positions for key off and on

Yes it's been a danger for the 3 years of had my car?? lol I'm with delcowizzid on this one

[taztassio]

might just be the idle air control valve sticking?

It is the IAC valve resetting , nothing wrong , thats a normal function on engine shut down.
