Yep. Driving back from up country on Saturday night and the oil feed line on the turbo came loose and starved the turbo of oil. The first I knew of it was the engine losing power. The turbo had siezed but I managed to limp home.
I've been researching the turbo options and they used a really small unit on the TD5 to maximise low end boost and response. However they are restrictive up top and run some very high shaft speeds. The unit I'm replacing this little turd with is a variable vane turbo. They have a ring of blades around the exhaust turbine that directs and controls the exhaust flow. The upshot is that the turbo behaves like a small turbo down low and opens up to a big turbo up top. Should make more power across the board at much lower shaft speeds.
Cheers
