Vauxhall insignia oil pump and seal

[Tomsta79]

Just posting this to ask about the oil pump and oil seal and oil pressure sensor . My car is fine but should I get the 3 above done for peace of mind are don't fix it till it's broke. It's a 62 plate so it's not the face lift version. And if I replace parts which make should of buy and much would people say average cost of the job all in thanks
