The smoke being emitted is a blue/white smoke, not a balck smoke that I have heard can be a bit of a problem. The noises from the engine is almost a sort of rasping noise, until I ease back slightly on the throttle and it seems to disappear. But obviously, by doing this, no acceleration is taking place! It's almost as if some of the power is being bled off elsewhere, with the engine not responding to the amount of throttle being applied.

As for my budget, I'd be looking to purchase an engine for approximately R4000, and I have a friend who would be able to install the engine for me. I would ideally like to purchase a 1.6 engine, and would value your ideas on such a thing.

Thanks
