ok gents, i've been working underneath my car on my back for some time now..i've tried every socket in my arsenal and none of them fit over my oil pressure switch nut. I need to go purchase one that fits can someone please tell me which size socket to buy so I don't buy 5 different ones only to return 4 of them

Thanx in advance.

 

well if it is the one on back of block i am 99% sure it should be a 21 or 22mm but a 7/8 wrench will work also

if it is the one on vtec sly i know a 7/8 wrench will work that is what i used last time to change mine for the green plug on vtec sly

 

thanx alot dude, i'm talking about the one on the back of the block

 

i say try a 7/8 open end wrench FIRST socket will poss break sensor when trying to put on or take off
