Rust stains leaking around muffler - Man Engines

just a fast comment

the rust dont come of the stainless steal ring if there is any in them

the rust comes out the engine and a loose clamps,
after all it is cooling water that go to the enginge to cool the hot air down
and inside the engine it is never paintent

it is the same with your central heating in your house if you are disconnecting a unit the water that comes out is also brown hell


so dont wurry to mutch about the collor just make sure the clamps are good closed (thight = thight )

DD4: Had the SS sleeve deteriorated or just seperated from the Muffler? And ,do you think the sleeve was the source of the rust, or more like pbekker's explanation?

Thanks, I'll keep an eye on mine
