Today I've had a go at doing my own service on the engine. Not a job I would like for a living. Its so awkward to get in and do anything.
All filters were low down and so bloody tightly fitted. I ended up hammering a screwdriver through the oil filter in order to undo the thread.
One lesson learnt, I did not heat the engine up enough to make the oil a bit thinner for the extractor to work fast enough.
Also chickened out on changing the plugs as my back was starting to ache and its just too low down. Job for Ross i think
