Hi, I have a Fiat Palio 1.2 NV Sports (petrol) from 2004 which has been having timing gear/crank shaft related issues of late. It first showed up in Dec 2014 when the car suddenly died on me (at about 97K kms). The Fiat service folks first changed the Driving Gear and Water Pump and within a month, the Driver Pulley and the Driving Gear once again. In about 4 months, the car was back at the shop and they again replaced the timing gear. At that time they said the crank shaft may need to be replaced because the crank shaft gear grove is broken. Now I have done 107K kms and my car is again not pulling from 1st gear until I rev up the engine over 4000 RPMs to get it to move. It it worth replacing the crank shaft now? Will it continue to have reliability issues even after the repair? Thanks!
