So I am in the process of replacing a damaged engine for my hyundai coupe 4 cylinder. The damaged engine just had the head gasket changed but the water pump will be removed to my new engine. I'm not sure exactly whats wrong with the damaged engine but the car is slow, sounds like a tractor and he said 'one of the pistons...compressor...not working or something like that.
Anyway just wondering might this particular engine be of use to anyone\would I be able to get any significant money(£50+) for it or is that not the case in which case I should scrap it?
