usually from my experience at perodua SC is RM300 to remove the engine and do what ever thing that u want to replace like engine mounting, clutch, flywheel oil seal. RM300 includes all. the oil seal itself usually is very cheap like less than RM50. plus some dealer can accept outside parts. just pay them labour. that is what i did for my mom's kelisa. bought the engine mounting outside, and ask them to install. and they can even install all 3 without removing the engine unlike most workshops.
