Karl, I meant to say earlier, when Tony's failed at Brunters a few years ago, his turbo looked fine, but it wasn't until it was properly inspected that aluminium 'swarf' was found embedded into the BACK of the turbine wheel. There was alot of materal floating around in that combustion chamber and I'd not be surprised if some of it said 'hello' to the turbine wheel on the way out. I hope not for your sake, but you'd not want to build that engine back up, then lose it again because the turbo goes on to shit itself.
