Was it the oil pump by any chance?

That was a good question.
Despite all the oil pump problems they have had in the past they are sticking with the rotary vane design oil pump on the Ford engines.

The design goes back decades. The Morris Minor has a vane oil pump but unlike the Ford one, seems to work.
BMW have used them for decades and I've never heard of one failing.
The Ford Australia design doesn't seem to be very well executed. Although in the Ranger, the 20,000 mile first oil change doesn't help either.
FAI make a very good geared replacement oil pump which is a fit and forget.
If I ever get to own a Ranger T6 that will be my preferred route.

I didn't know that. I thought it was a Ford design.
TBF I replaced the oil pump on my 2.2hdi Boxer due to the many failures reported. The previous owner had had the van serviced by Peugeot every time and the oil pump was fine when I took it out.
Its one of those parts you can't predict what will happen to it. It could have outlasted the van, it could have failed the following week or the new pump could also fail tomorrow. What I did find was despite the regular servicing done by Peugeot the oil pump suck up tube needed the strainer cleaning out. TBH that surprised me.
I'm still very much thinking about doing a oil pump upgrade to the geared conversion although its become less of a priority.
A fellow windie with the same year Citroen Relay with less miles had his oil pump fail. That's what made me change mine pronto.
