Turbo Heat Shield Rattle and Removal (Merged Topic)

[our06t]

I'm planning on removing mine but only after I get all the manifold,dump and turbo ceramic coated

yeh, I left mine on, even though my zorst looks sweet in the stainless now.

Strongly suggest you leave the shield in place. It does an excellent job of keeping the radiant heat (note radiant heat) from the exhaust and turbine casing out of the engine bay and thus greatly protects your engine bay components from damage by radiant heat soak. On a slightly lesser level the shield also contributes to keeping the heat where it will do the most good.

The shield is I think, and I could be wrong, is a metal ceramic composite. In any case its ability to insulate, by reflection at least, is somewhat deceptive and far greater than you would imagine; the engine bay is an area that that is hot by human terms so it is difficult to appreciate just how effective the shield is at doing its job. Just remember the turbine casing and exhausts are big heavy lumps of metal, frequently big heavy lumps of red, hot, metal.

As alluded to earlier the shield also keeps the hot bits of the engine relatively hot (though there are additional and much better measures you can take such as wrapping or coating) and the cool bits relatively cool (though again there are additional measures you can take to insulate the appropriate components). On a fundamental level the difference between hot and cool is how and why your engine actually works and keeping that hot-cool contrast as wide as possible is a prime element in any engine’s efficiency (this applies to petrol engines, turbos, jets, steam engines, diesels yada-yada). This is why some people go to the trouble of ceramic coating or wrapping the exhaust and or the turbine casing and on a somewhat more distant level, insulating the cool side, intakes systems.

Can we remove the heat shields for short trips?? I want to take mine off before I get to my mechanic to save him all the hassle of pulling them off.

Dont see why not if it saves you a few bucks and you will know in future how to remove it then.

You run the risk of melting your overflow tank and/or boiling your coolant if it's off for an extended period of time. Leave it on...

I drove with mine off 4 ages, the reservoir only melted when the turbo was high mounted

I have this same problem at the moment. I have taken it to the mechanic who want to change the cat straight away, but I am not convinced there is any failing cat symptoms. Plus the vibration really only occrurs at idle. power still seems fine.

My plan was to remove the heat sheilds and wrap the pipes with exhaust wrap and re fit the shields. Anyone see any issues with doing this.
