Xulfiqar bhai I have corolla altis
I hear a sound like chirping while the engine in hot position.i open the inlet and remove the jaller as well but the sound exist too.cold startup is ok.engine pick and power is good as well in cng.consumption is too good.engine inlet also contains some drops of oil as the mechanic says that ur valve is leak.but that are only 4 or 5 drops.engine does not reduce oil,i think 1 litre consumption oil after 2000 km is normal in cng altis.please ensure me that my valve seal is leak or not?thanks
