pressure sensor switch question
 

my pressure sensor switch is leaking badly (squirting oil all the way up to the engine cover). I am a student and only have some tools with me at school. Could somebody tell me what size socket fits the nut for it so I don't have to buy a bunch of sockets and then return them. I can't get any calipers down there.
Thanks

Jurhip,
I think you are referring to the oil pressure switch on the top of the engine just aft of the distributor.
Go to a parts store, tell them you want to buy a socket that will fit the oil pressure switch for the 914, 911 engines. BTW, you can buy a new switch for $2 or $3 bucks, much cheaper than the socket.
