tried changing the oil this afternoon and fell at the first hurdle. namely, I can't get the nut undone. i'm thinking that facing the car - bumper in front of me, I need to put the spanner on the nut and pull towards me - correct? seems rock hard - maybe the garage that serviced it were a little over enthusiastic. anyone else encountered this? - tellingly the nut screwed in has a hole in it while the official Daihatsu replacement I have is solid.
