Tin can rattle on gear change

dvdman1 · 16-10-2019 7:16am #1

This noise only happens when i first begin using my car..
.....
when i change gear upwards then push the accelerator in the next gear it creates a sound like a rattle of a tin can.

After driving and the cars warmed up it doesnt make this noise, seems to be 1st start only.

Any help or ideas on what this is would be great

Fiesta 2008 1.4 petrol

Loose heat shield?

Doesn't rattle for instance if i stop on a journey then restart the car and continue....would a heatshield rattle only on 1st start of the day

Sounds like you're just changing gears too early, go up the revs a bit more and see if that cures it

I dont think its a case of that, im very consious when im doing the start off to see if the sounds still there.

Does noise go away if just light press clutch pedal?

It could be pointing to bearings on the way out:
release bearing(top of pedal) or pilot bearing(full depth)

And it would most likely rattle just on the application of the accelerator after changing up gears on a cold engine, hence why i suggested going up the revs a bit more before doing so.

I've an automatic so putting it into D didn't always create a rattle,,,,idling for at times vv frustrating, thought my car was knackered

Over revving on starup and gear change seems to make it disappear, once i down the revs i hear the rattle.

Have a look at the heat shield so, you may just have to bend it away from the exhaust a bit or there may be a bolt loose.. easy fix.
