Oil pressure switch

[Muderfahker]

First timer posting here.

My 03 protege5 is leaking oil, I have traced it to the oil pressure switch. I got the part and plan on doing this little job on my next oil change.

Is this a common problem?

Anything I should know before I mangle another piece of my car?

Any information helps. Thankya

i had a leaky one too, cheap part, my mechanics did it for next to nothing, i dont have the equipment to do it myself, nor ramps.

my car had 3 different leaks, all are now fixed, im just awaiting to replace my valves in the crank, burns oil like crazy

The switch is on the back of the block, next to the oil filter. The shop manny has a pic.

When you're under the car looking up at the oil filter it'll be to the left of the oil filter a bit- goldish round knurled looking bulb (when clean) with a wire connected to it.

im still confused... seems like we are describing the knock sensor

<---- runs out to take a look under the hood

Use nylon thread tape to install (if it doesn't have an O ring).

How the hell do you remove this little beeyotch? Dammit.

With a deep socket or open end wrench

Take the oil filter off first and give yourself a little more wiggle room, and I can attest it is an awkward bastard to get off.

What size is the ******? I'll have to buy one. 23mm or 24, but because I can't fit my shallow socket over the damn thing I can't tell.

Check your replacement part. Socket size should be the same. Let us know if it fixes the issue.

Thanks!

@808mp5...the knock sensor you are thinking of is to the top left of the oil filter (top of cylinder 1)

Also take off intake manifold support bracket (dog bone shaped) to give you more room.

The new one is 22mm. I bought the deep socket yesterday. It doesn't fit the oem switch. back to Autozone.

an adjustable should work fine...unless its rusted in there that bad.

Adjustable won't work in there, not enough room and the best place for an adjustable is the dustbin. Most of the time all you manage to do with an adjustable is round off the corners.
