Tractor noise, continous white smoke on acceleration and idle, no power, hissing. Help!

[SOLIDSNAKE]

Hi, I have all the problems listed above,

I know the injector seal has gone because of the tractor racket, I am re seating tomorrow. I may be loosing compression out of there too.

If I am losing compression where is the white smoke coming from?

I need help with this!

Unburnt fuel

I can only suggest that one of your injectors has become damaged and is allowing an uncontrolled flow of fuel into one of the cylinders.

I have no Idea what it could be currently I am planning on recutting the injector seats again, do you think it could be burning oil?

It could well be oil. What does the white smoke smell like?

I'd suggest coolant was getting into a cylinder, but you've done nothing to disturb the head gasket. I previously suggested a damaged injector as it seemed most likely fault considering your recent efforts.
