more specifically i'm wondering what size socket i need for the glow plugs to remove them, however having only done this job once on an escort i'd like any advice i can get as it was a pair last time!

I understand vauxhall glow plugs have a knack for snapping so i'll use a generous amount of plus gas before getting them out and warm the engine, and i'll copper grease the new ones.

Cheers

Thom
