Renault-Logan (India)

Hi, I own a 2009 Renault Logan Diesel which has a K9K DCI engine. After completing almost 115,000kms I had the engine rebuilt. At this time I got the Compressor and Cooling Coil of the AC changed too. The problem I face is as follows:
1. When the engine temperature goes high the Car engine shuts down when I press the clutch to change gears. If I switch of the Compressor then the car restarts again.
2. On RPM greater than 2500 the engine emits black smoke.
3. The engine leaks oil despite of changing all gaskets.
4. At speeds greater than 100kms the engine knocks slightly and does not give adequate pressure.

I drive almost 4000 kms a month and the car has clocked almost 155,000 Kms. If you solve one problem another starts. I have even changed the starter switch and the Oil Pump. All parts are original from the company.
