    So did I.

    Have we all been misled?

    Did it split length ways or around the tube? I was thinking I'd have an old bend to get you through the weekend but the turbo I just removed had a cast aluminium bend in that spot.

    I recently bought some silicone hoses from this eBay store. They seem fine, although I've only had them about two months. Good prices and fast delivery, although you'll probably want it today I guess .

    And, as with most things in life, there's silicon hose and there's silicon hose.

    The good stuff isn't made in the east and it uses more layers of fabric braid than the cheap stuff.

    Massey Ferguson makes a spiral steel wire reinforced 90 bend which is a straight replacement (South African and UK models at least) which I used on all my 300Tdi's after the first time they split.

    The silicone hose sold by Devon 4x4 comes pretty highly rated...

    I would have thought that the right angle bend immediately after the turbo would be subjected to quite a bit more heat than the hoses further down the line and that the later ones would therefore last a lot longer.

    Or is that just wishful thinking?
