Pls kindly help me out on my ford focus engine cracking sound anytime I accelerate fast but not nocking sound

 

Where does the sound seem to be coming from maybe engine compartment or maybe under the front of the car ?

 

The engine part

 

Very light cracking sound when I accelerate fast

 

Without actually hearing the sound, it could be an exhaust system leak possibly coming from the engine on down to the exhaust pipe(s). On acceleration exhaust pressure increases and that is when some leaks will appear..

 

It sounds like metals cracking together with force

 

I don't know if this is the problem with your vehicle, but if it is a cracked flex plate for the trans, you should have it checked out ASAP.
