Exhaust manifold wrapping

[Victor Lee]

Back in mid 1990's, I had the custom extractors on the 3.0 24v wrapped to reduce the heat in the engine bay.  Less than 5 years later, they had rusted from the inside and could not be saved.  I got my next set ceramic coated.  These are the same set that are on the car now. 

So that's a big NO from me for wrapping!

Hey Poohbah,
Here are some pics of the heat shield and snorkel on my GTV 2.0.
Cheers 

cheers mate, no hurry. Sounds like it was a lot more complex than the basic one on mine.

Thanks for the pics. I have seen those before. Is the snorkel meant to direct cool air from airbox over the manifold?

As it turns out, I believe I have identified one ill effect of removing the DIY heat shield from mine. Since doing so I appear to have cooked the elbow connection on top of the AC compressor and one of the hoses. Meaning it has split and the other day broke off, resulting in the AC hose resting against the manifold itself. Now the insulating material prior owner had wrapped the hose in has gone very crispy. (The AC compressor on mine is non OEM, which seems to have also necessitated the relocation of the battery to the boot).

that was not a shield as much as it was a hot air collector for the aircleaner
so in cold climates it had thermo valve on the inside the air box and opened the hot air
