hi

My vehicle is a DDIS engine maruti swift 2009 model clocked approx 33000 kms.

I have been hearing knocking sound in my car engine, loss of power and clutch thuddering from few thousand kms. My car has an engine oil chnage every 6000 kmsand we also chnage the filters with the oil change. The macanic has no clue why this is happening. Please suggest as iam worried as to what should be done.

Thanks
SVS
