Speed Triple 1050 Oil Pressure Sensor

Hi all,

Anyone experienced an oil pressure sensor leaking.. oil?

It's a 2005 Triumph Speed Triple 1050, I've noticed a slight oil leak and traced it upwards to find the source at the oil pressure sensor, it appears a washer has aged and allowing a small oil leak which is running down pretty much everywhere. (Casings, hoses, bottom fairing, gear selector, side stand).

It seems very odd to me that something like this would develop a leak and wanted to query if anyone knew of this happening before? I've also never experienced an oil leak from an upper region of an engine, normally this is a bottom thing due to physics. I've no knowledge how an oil pressure sensor works,
should there be oil feeding into it?

The other question is how easy is this to remove and replace as there's no wiggle room to get a hand in, but may be able to get in a 22mm tall socket in to remove after disconnecting the electrics. I'm assuming the casing is threaded for this sensor.. or should I be expecting a nut inside the engine area?


(Above pictures differs somewhat for my model) but it appears to be the second washer (#24) from the bottom up which connects to (#22) that's the offending part.


(Not my bike)

The oil pressure switch has also been causing the dash light to illuminate as a result after riding, I've got no concerns for this as it's been a previous problem for me for the last 1000 miles and tends to only illuminate on/off when idling after a 20 miles period and not applying any throttle/revs which when is applied the light turns off.

 

Oil level is spot on, checked this afternoon and idle speed hovers just above the 1k, tested today when the light was on held at 1500, light only comes on when drops back to idle.

 

Light is never on when moving just at idle, leak is from switch which I’ll bw replacing just looking for advice on how to get to it and if oil should be in the sensor area where the leak is.
