the engine noise is increased i think, i will upload video soon.
also the AC compressor bearing is worn out, today i checked from AC mechanic and he diagnose that the compressor bearing need to be replaced. my question if the AC switches ON, should the compressor bearing comes into action via compressor clutch or this bearing rotates even when the AC is off (in winters). if the bearing rotates with the engine belt then may be it is the noise of that bearing. (will change the bearing in next two days, will let you know)
Another point =>
1: the noise increase with the accelerator.
2: when the engine is idling & AC is ON, & i accelerate the engine from throttle, the engine rpm goes up when i release the throttle and the RPM drops, upon coming down (near to end) a TICK sound is coming from the engine bay & i am pretty sure it is TICK of some relay.
what if i go to mechanic and he recommend me some components to change inside engine, what component you expect, he will point out.
