car been feeling a bit weird over last few days. a bit 'aggressive' at the back end - kinda jolty and a bit unpredicatable.

turns out im loosing oil! weirdly theres no noticable drips on pavement, so it must be fairly recent, but it's collecting oil enough to turn into drips.

gonna grab a new plug seal for it tomorrow before it gets too bad and costs me a diff.
anyone know the size of the seal needed? honda is a drive, but local parts shop is a 5min walk from work.
