Guys thanks for the help the problem is diagnosed. Mechanic perform the Compression test and only 1 cylinder was working.
Actually this is the same mechanic who made the head work Valve etc 3 months back. And was giving me guarantee that these valves are original and would last long 35,000 km minimum. But as i told that only 1 cylinder was giving pressure and after opening the head, Valve condition was extremely bad.
And he said keh main ne Original Valve hi dale hain aap ki gari ne Mitti (dust) khenchi hai Air filter saaf nai tha ya Air Filter box sahi band nai hua. He started to blaming on me. I said bhai Air filter ager itna hi faulty ho to car missing kerti hai aur ager box khula reh jaye to Sound se hi pata chal jata hai. He said keh i will do the work free of cost ager koi keh de keh yeh problem kisi aur waja se hui hai kisi bhi mechanic ko le aao.. So guys this is the story can someone explain could it happen mitti khenchne wali story..
