Hi Sir,

I am very worried, I got Honda city IDS I 2006 model , CNG is installed there.
Few days ago I started hearing a strange voice ..

When I start my car there is no problem starting is perfect and some time I see water coming out from clincher .
When I start my car after some time means when it is cold there is no voice, but after some time it starts giving me voice like GRRRRRR.GRRRRR
and this voice comes when i leave accelerator , and when I push Clutch
the voice gets louder and when i leave it the voice gets a bit less louder bit still comes, while hearing from engine it comes from
engine area ...

I checked with mechanics some says it is a crank sound and some says it is coming from gear , i am upset , what is that ?

any clue ?
regards,
