Guys, It only happened when, The car is in gear Throttle is down 1000-1800 rpm However, when I took it to the dealer, the car didnt make the noise, guess the car is warmed up, I dont know, but they keep on making statements that I shouldnt rev the car above 700rpm, it can crack the pistons. But I left the car there, I told them to check the timing and hopefully when i pick up the car today, everything is good.
