Hi There, I have just bought ford falcon 2001 (LPG only). when I checked it via mechanic, he found two cylinder out of six got some low pressure problem. Therefore he advised me to change the engine or sell the car. I got it for 3100 and to repair it I mean to change the engine....it will cost me around 2500. Anyone have any suggestions ? or does anyone know any mechanic who can do it bit cheaper.
