Decided to refit the farty collector box, after last weekend's angle-grinder bolt removal fest. Inserted new Alu rivnuts, and set them in liquid metal. Set to, and it was all a bit awkward fitting the collector to the exhaust pipes. Judicious use of a lump hammer ensued, and all was well - plonked the silencers on, and tightened up all the clamps. Key in, fired up, and it sounded like a squadron of Lancasters was taxying threough the garage. Investigations with a lit ciggie revealed a blow between the exhaust and the collector. Once unbolted, the gasket sleeve fell out in pieces. Ho hum, on the 'phone tomorrow, then. At least the MOT's not due until the 30th.
