[QUOTE="damnu, post: 14208, member: 8508"] Hi All,Decided not to transplant and stick with my current M40 lump. Planning to do a top overhaul because the engine smells of petrol after each drive. Been getting stronger lately. Would also want to fix up the tappets. Would anyone know how much this would set me back? Since I'm going to take the top out, what else should I look into as well? Would also want to seek the opinion for the following:1) Port and polish (was told that the improvements would be minimal, what's your take?)2) Since the car will be in the workshop for a while, should I just overhaul the entire engine? If so, what would the cost be? (asking coz was thinking of balancing the crankshaft but was also told that it's minimal, doesnt justify the investment)I've ran through the idea of a transplant a gazillion times, so it's safe to say that I'm pretty sure I'm going to stick with my current lump. Any other improvements I can make to the engine? (just to improve efficiency, and if possible some extra juice also)Would like to know what your opinions are.Thanks! [/QUOTE]
