I was quoted RM5000 by Soon Eng Hup Segambut for N42 2.0 engine back in April this year, but please open the head and replace necessary gaskets, o-rings, seals before you put in to be on the safe side as you do not know the engine's history. With labour you might spend rm7-8k in total....I rebuilt my engine instead but it cost more and takes longer to complete but the engine feels new.
