hi guys, whenever i turn off the engine after reaching operating temp, i can hear a loud crackling sound coming from the exhaust at the front of the car.  i'm pretty sure its not the manifold, but i've no idea if this is serious or not.  anyone have any ideas for me?

 

thanks

Hi Frankie,

 

Jim has made a good suggestion.  Jaguars do like a little bit of of energy now and then.  Clears away the cobwebs, so to speak.

i think your find it does this as its cooling down as jim says above i had the same with cars and i can also report no problems 

regards ron 

As with all cars I would have put it down to the cooling down period as Ron has suggested.

I get the same noise, too.

 

Being a former steelworker I guessed what it was!

Peter, Steelworker? riveting:-)

thank you kindly dear chaps.  I was beginning to get the fearties and imagine all sorts of problems and was planning to start doing the lottery on a regular basis.  

Thermal contraction sounds a perfectly reasonable answer, so thanks one and all.  it was just a bit unnerving hearing it.

 

thanks

Hi Kenny,

 

While ostensibly I worked in an office, my alleged expertise was in job evaluation, work study, and bonus schemes, and the only way to operate properly was to spend more time on the shop floor, and I have been in every department in many steelworks.

 

In the sheet steel hand mills the quite thin sheets were left to cool before being sheared to size by hand, and you could hear them contracting slightly but noisily.

 

Very interesting work.

 

Regards,

 

Peter.
