hi

my bugeye was making slight rasping/scrapin noises everytime i put my foot down. The bloke at the garage said it was jus a loose heat shield, not to worry too much and come back later to get it removed/replaced.

So what is a heat-shield and wot does it do?

 

probably the heat shield round the turbo

it shields the engine from the heat of the turbo

i would get it tightened up rather than removed, hot air in the enigine bay dosn't help anyone

 

well i know it was directly under the gearbox somewhere cos that was where he was lookin at.

 

remember that its there,usually for a reason,to shield something from heat,so best to keep it on.

 

"heat shield" - it does exactly what it says on the tin.

The guy was probably looking up the back of the engine to the turbo heatshield, which is the one most prone to rattling. Without it, hot gasses rising off the turbo will mean that the intercooler can become an interwarmer, which can in turn cause det, power loss or even engine damage if you're unlucky.

 

Heatshield for the turbo is just above the gearbox area. Mine got a split in it, what a horrible rattle. i was lucky to get it replaced as a post warranty.
Don't remove it. It's there for a reason.

Yep defo keep it mate, your No 3 cylinder will be hot enough as it is let alone removing that sheild. Fix or replace it matey
