Recently my engine started to block and give out smoke instead. what is wrong with this engine!!! It really troubles me a lot

Engine is blocked because of many reasons.

1. the oil drainage switch is turned off or the switch blocks

2. The spiracle of fuel tank cap blocks

3. The block of strainer in sedimentation glass; or the block caused because of dirt deposition inside the oil-taking joint of fuel pump

4. There is air in oil-way

5. Dirt deposition of fine filter or coarse cleaner

6. The fuel delivery pump doesn’t supply oil or not enough oil supplied.

There is something wrong with engine, you need to be repaired

Blocked? Need more information than that.
