Hi all,
End is right, like he said, the egr valve was hard to remove, I don't have a crazy skinny socket. So at the end of the day I couldn't remove it

. Thinking of removing the engine cover and use a 12mm key instead of socket + ratchet. Hope that works. Someone knows how to remove the cover without breaking it? I try to lift it up but afraid to break it.
But anyway where did you guy get a long skinny socket like this.
