Hyundai ix20

intermittent grating or whirring type noises. Sometimes happening when engine is cold but can also happen when in the middle of a journey. It sounds like something is rubbing against something else. Sometimes happens when changing gear but...

Ticking noise between gear changes at low speeds.

Fuel starting to leak along joint between upper and lower half

can anyone advise me how this can be fixed. The key can be removed when left in reverse or drive gars.

Often unable to pull away to begin with in first gear without really bad judder no matter how carefully I control the gas and clutch. Problem getting worse. Only happens on first couple of pull aways and then car is fine.
