oil pressure switch leaking

[versatile75]

I have a 04 1.4 vauhall astra that's leaking oil from the pressure
switch, there is a ribbed oil seal that sits on the sensor pickup
that must be naf, if I get a new sensor would it come with a new seal
and has some one had this problem and managed to get a replacement
seal on it's own,
Cheers

Presumably the ribbed seal you mention is on the outside of the sensor?
If thats it, it is there to protect the wires from water ingress.
Any new component will come ready to install.
