Well getting ready for ford fair, took the car out and went for a spin and white smoke is coming out of the exhaust straight away, also misfiring on cylinder 1&2. She does run quite warm. But no oil in water or cream/mayonaise. The coil pack is working as the leads are sparking against the body. What is wrong with my rs turbo series 2? She's running Zvh Efi, cosworth turbo, gen 8 management. Rebuild done 7k miles ago with forge Pistons etc...
Thanks in advance.

 

Sounds like the headgasket to me mate especially as it's misfiring aswell

 

hope not, but to me too...
have you tried to blow compressed air in the cylinders?
(through spark plug holes, with a high gear in, e-brake & a brick to stop a wheel... etc)
white should be water...
if the crack in the head gasket is between the cylinder and the water channel, then you should see bubbles in the water expansion tank.

if it is between cylinder and oil channel, then you might feel blowing a little from the crankcase (or from the valve cover) ventilation hoses. not every time this one works...
