F4R Clio Sport Timing Belt?

I'm considering doing my own timing belt on my 182, but read that these are horrible to do and autodata is listing 6hrs, I'm wondering whats hard about them? ive done Vauxhall chains and belts for instance the 1.3 cdti with a floating crank and no timing marks ive done several of them myself.

Is it that the Renault engine is also a floating crank and no timing marks that makes it hard compared to other engines?

Cheers
Mark
