Hope it isn't the turbo as it wasn't cheap, it's not the engine as it was fully rebuilt 2,000 miles ago form top to bottom, I havn't driven it yet and saying that I thought it was starting to clear a bit. I will give it a good run in morning and see how it is then. Any ideas on the hanger, the instructions said fit when hot but you still only have half a turn either way otherwise the top bolt goes in cross threaded.
