i went to mazna to fix some oil leaks of my engine and then they inspect the engine and they recommend me to replace the engine ,engine burn nearly 1l of oil around every 3000km, my car milage also around 240000km , According to what they said they just a replace engine (not included coils, power steering motor,AC compressors. etc ). im planing to keep my car at least for next 4 years so i want to make this repair last long so thats why i thought replace whole thing one shot. yes i called colonial and they said they accept parts from outside because they don't have parts for my car (BJ5W)
