Peugeot timeing
its a long process for the novice. I suggest getting a repair manual at your local autoparts store to help in your troubles. The process includes finding the timing marks, partial disassembly of engine to access timing belt/chain. To sum up the process, you disconnect your battery, remove timing chain cover, line up timing mards on camshaft/crankshaft which could be dots, marks or grooves, replacing the belt/chain, and reassembling engine. The repair manual will give step by step instructions as well as pictures. To post all that here would take more than 10,000 charecters of text, which fixya limits us to 10,000 charecters. Very long detailed list of procedures for sure!
