How do you set timing with dual cam for peugeot 307?

To set the timing with a dual cam for a Peugeot 307, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the camshaft timing marks to their respective positions; the marks should point towards each other or align with the engine block, depending on the engine type. Use a timing tool or locking tool to secure the camshafts in place, and then install the timing belt, ensuring proper tension and alignment with the crankshaft mark. Finally, double-check all alignments before reassembling components.
