Depends on the car.

If you drive a Koenigsegg, like I do

can you explain this a bit better?

Christian von Koenigsegg built me a special edition, called CCX^2, don't know xactly what he meant by "squared" though.

Say Hi to Christian when you see him, from me!

Ohhh good ol`Christian! I still remember when we got drunk and destroyed a Pagani Zonda with baseball bats.

The ticking noise on my car is parts falling out the bottom of it onto the floor.

I created a metal pan to run along underneeth to catch them so when I come back to it start up is so much quicker, dont have to spend so much time finding all those loose bits... I can normaly put it back together in about 2 hours now, I find it gets worse after a 2 min drive.

I suppose its quite time consuming if i'm just "nipping" out to the shops as it could take all day, but i just tell the wench not to stay up.

My '58 Plymouth Fury ticks when I turn the engine off. I was out working on it one day after apparently some vandals had gotten to it and I heard a noise and then turned around and noticed that the carbs had nice new chrome air cleaners. Weird. That car scares me all the time, it's like she has a mind of her own. She's always right where I parked her last, but people tell me they see her all over the place, but I never remember being at the places they say they saw her driving around. She had the brightest headlights I've ever had in a car too. At least she's not like my last car. It belched fire, bent things and turned into a werecar all the time. No ticking when I turned it off though, just an occasional belch and flame.

Mines does a similar thing sometimes. I sounds like it's the fuel pump still running. The relays sticking a bit, so if I put the keys back in the igition and turn it on and off it usually stops. Could be that.

One cause for a car and powerplant making such noises on cool-down is that they were very hot. I have seen it myself, when you take a car that has been run hard is immediately shut down.

Those noises may be the car's way of asking for gentler treatment, to allow the powerplant a few moments to stabilize the temperatures and allow a few moments of idling time.

For instance, if you are running a turbo, coming to a dead halt and stopping the engine immediately has dire consequences. The oil inside the VERY HOT turbo will cook itself, ruin the bearings. The cure is just to allow a few minutes of idle time so temperatures can get back under control.
