Hi Colin, on your engine if the cambelt breaks there is a large chance that piston to valve damage will happen!!! if you have ruled out this damage you need to get the #1 piston on TDC this should mean that a dot on the crankshaft pulley aligns with a mark on the engine casing and then align the camshaft dot with a triangle mark on the cylinder head then the engine is timed The firing order is 1,3,2
