Yeah--tell me about it!
With only 142K miles one would think it was a long way off from such a thing.
I was having doubts about how sound this engine was even though it seemed to run strong pretty much always. When coming to a stop the oil pressure gauge on the cluster would fall to zero, a warning chime and message would appear saying "check gauges". Initially I thought it was simply a bad pressure sender but decided connect an actual gauge to read what was happening.
There was a lot of ticking and what I'd swear was a loose rod or possibly crank slapping---none of which were very comforting.
At a hot idle I should have had about 25psi---I was lucky to hold 8!
Just off idle I'd get up to 60+ psi Discussing an engine swap with a knowledgeable mechanic friend he suggested I run a concoction of Rotella 15W40 and a quart of Lucas Oil Stabilizer which I did.
With that oil installed my cold idle was 70 psi, when warm it was struggling to hold 15-----even that was dropping a bit. Given this is a work vehicle and dependability is the key word I wasn't going to put this on the road in its suspect condition.
If interested here's a few videos of the final testing: https://www.youtube.com/user/jwa718/videos

Who knows how long it would have lasted in that condition---replacing it seemed prudent.
