I had started to get a weird buzzing on throttle above 2500rpm under load, and then over the course of a week or so had started to burn oil on start up, so much that she would misfire and splutter every morning and afternoon - v embarrassing and not healthy at all. I drove to Parsley Hay car park one day after work to go hiking, stayed the night in the truck after finishing late. She took some turning over in the morning and choked in to life in a cloud of acrid smoke. After inspecting the intake I diagnosed bust seals and worn journal bearings.
Access was an arse at times, but on the whole removal and refit was straightforward. To split the compressor and the turbine I had to remove a collar similar to an exhaust clamp. Once that came off the two halves just fell apart... not! Dean came up with the ingenious solution of 3 bolt 'presses' placed between the housings, with a socket butted against a nut on the end so that as you wound the nut, the sockets pushed the compressor away form the turbine - see pic 1013. Once they were split, disassembly of the turbine shaft and bearings etc was OK, and I only pinged two of the tiny little circlips across my lounge.
Rebuild started on Saturday and then everything tightened and checked over on Sunday. I'm pleased to say that she's back to her usual immaculate behaviour
