Can someone identify that sound?
Is it expensive fix?

Sounds like a sticky starter not pulling back in time when the car starts

 

Can it be something related to motor chain?

 

i would have to agree w/seanjordan starter drive issues engagement/disengagement.

 

The timing chain? No such thing as a motor chain. If that is what you're talking about only you can differentiate that from popping the hood and have someone start the car. The starter and timing chain are on 2 different sides. Once you know what side it's coming from you can answer the question.

A loose timing chain would cause a slap and if it jumps time the car wouldn't start. You'll also hear it clicking (chain running against the engine) until oil pressure build up. You'll definitely have to open the hood to get a further idea.

 

Thank you for finding time to answer my questions.
