I think the 2.3 is similar to the 1.9 duratec.
you need the crank timing pin tool which inserts on the exhaust side of the engine. you then need special tool (205-126) to hold the crank preventing it from putting pressure on the: (M6 bolt inserted through the crank pulley into the front cover). there is also a special washer between the pulley and crank. you torque it to 100NM ??? and then turn the bolt an additional 90° (nice long piece of black pipe over your breaker bar for torque)
- Just noticed yours has a keyed crank... so i assume you may be able to do this with the timing pin tool alone, but that seems like a lot of force to bear? may be worth checking with cosworth
I'm not sure you can do it with the engine in the car. I tried once and it wasn't happening for me.
cheers.
