Hello I recently bought a Grande with the starjet engine. When I accelerate between 1500 and 2000 I get a strange noise like a very light metallic rattle. Any ideas what this could be I was thinking the camshaft variator maybe?

have a look through the last couple of pages in the Grande section,

several similar posts recently,

It's strange because it's only happening when accelerating (100% load) from ~1500rpm to ~2000 and then silence, all normal.

(also if i'm going uphill the noise is much louder)

The heat shield on the manifold is held down with about 6 x 10mm nuts.
When i say 10mm, i assume they might be, as ours had all but disintegrated.
Two of them to the point that they were no longer serving any purpose.

I assume the sound you are hearing will be the same one we heard, which was the heat shield resonating.

Hard to describe, but sounded like a shhhhhhh, or even zhhhhhhh if that makes sense

yes shhhhh makes sense to me.(y)

Removed shield (it's 7 x 10mm nuts) Noise decreased a lot. It's still there, but I think it's the exhaust mount under oil pan?! Can't tell for sure.
