Hi,

The exhaust manifold heatshield on my 1998 L501 ED-20 engine has got a bit rotten round the edges, but worse still a couple of the bolts are badly rusted. It's also rusted round one of the bolt holes so it's developed an annoying rattle.

So given the rusty bolts it looks like it will be hard to fit another. I'm assuming that running without a heat shield would lead to melted plug leads and worse? Would it be OK to run with exhaust manifold heat wrap instead or would this lead to a cooked cat.

Cheers.
