Engine Mechanical problem
2003 Peugeot 206 4 cyl Front Wheel Drive Manual 47000 miles

im having problems locating timing marks on a 206 gti (134bhp) 2003 i have found the top 2 pin holes but cannont find the flywheel lock pin! also in the autodata book it shoes this car with 4 bolts holding on the bottom pulley but this car only has one centre bolt so there is no lock hole? i have contacted peugeot but they have qouted me £500 + vat to replace the belt and wont give me any infomation. please have you ever heard of a problem such as this? im not sure now that the engine is what it should be? ive been through diagrams but still cant understand why this car is different from the book? thanks
