What is the worst noise your car has ever made?

For me the worst noise ever had to be the sound of a con rod going through the sump (and right through the exhaust downpipe which is made of iron).

My second worst noise was the metal snap and grinding noise of a brake disk snapping as I started braking hard.

The most frightening noise was a spark plug popping out. It made a big bang, I lost compression on 1 cylinder and it sounded like the engine had been shot. Thankfully a new spark plug fixed it. (Must remember to tighten them up in future.)

What about you? Whats the worst noise your car has ever made and what were the implications of it?

I haven't experience any worse noise coming from my car yet,because every time i hear a little noise coming from my car, i will check where is the source of it and bring it to the mechanic to have a look.

Maybe this is the worst noise that i had encounter,that is i used up my brake pad and grinding sound of the disk brake.

oh god the towing hook thingy is right underneath the bumber and sticks out about an inch or two, i was rolling up a kirb (that was in front of the car) when i heard this very loud crunch!

i thought my bumber had just got mashed by the kirb but it was the bloody towing hook scared me to death! now i dont tend to park at the ends in car parks

When I had my exhaust fitted, I needed the bumper modifying slightly so it would fit...the sound of somebody cutting a piece of my car...ouch! I didn't wanna watch! Other than that, I haven't experienced any bad sounds.

skidding into a roundabout. going over the kerb smashing up 3 alloys and blowing out 3 tyres. that was rather scary . and the worst part i was only doing around 30 at the time. it was wet and slipped on loose chips.
Did manage to control the car through the 1st half of the roundabout but couldnt get it to go the other way. £700 to fix up. and no bugger stopped to help.
week later a wagon driver did the exact same but on a much bigger scale
