My shogun is borked. 2.8 turbo diesel. Fine when cold and on short journeys. After about 20 minutes I get a loss of power and shit loads of smoke out of the back. I'd think it was the turbo or the injectors but its fine when cold. Only theory I have is that the seals to the turbo are fucked but when the engine is cold the seal is better. When it all heats up it expands and the turbo doesn't work. ????? I need to be in the know when I pay for a *bloke*
