Hi guys , just bought an alfa romeo 159 3.2 jts with an engine problem. The previous owner said it's the timing chain, i've also noticed that there coolant reservoir is empty. I got a new battery and tried to start it , it hardy started for 2 sec making a loud rattling noise and shaking.There's a video with the rattle as i try to start it . The car has 122000 km . What do you think ? What should i expect ?
