In my experience the hoses that connect to the engine are more susceptible to blowing than the two which are closer to the cooler.
Has anyone had the reverse happen ?
my working theory is that the two hoses closest to the engine have more vibration exposure, and possibly a little more conductive heat degradation.
No blown oil cooler hoses yet (knock on wood) but I am going to take a good look at them when I do the next oil & filter change, probably over the Christmas holidays. The car gets a 25-mile highway romp from me once or twice per week all year round to keep all the parts working properly and fluids moving briskly. My records show that I have not had to perform any maintenance on it thus far in 2023, which is damn hard to believe....
Mine started leaking profusely at the engine run on the driver's side and I think you are absolutely right about those sections being most vulnerable due to proximity to the engine.. But mine didn't "blow". It leaked between the tube wall and the hose as though it had lost compression of the ferrule.

my 2002 XKR has been the most reliable used car I’ve owned, and that’s accounting for 50+ years of buying used cars for my daily drivers.
when I purchased the car 6 years ago it had 116,000 miles on it and had just had the timing chain guides replaced by the previous owner. On my test drive (in the blowing snow in January Iowa) the CPU fan started an intermittent squealing, similar to a stuck pig. The seller turned pale, thinking he’d lost the sale. I had a pretty good idea where the squealing was coming from and told the poor guy to relax, that I wasn’t scared off yet. I bought the car and had a nice 400 mile long drive home in a prairie blizzard the whole way.
After replacing the fan (thank you SNG Barratt) I never spent another dime on car parts other than the consumables until the oil cooler hose blew out at the crimp. that’s currently about 75,000 relatively trouble free miles. Pretty good for a car with a bad reputation for reliability.

PS : I’m getting pretty close to 200,000 miles on the car. It’s almost broken-in .
zray, I agree 100% with your theory. It makes the most sense. A quick trip to the garage to refresh my memory and the right side engine hose is the one that blew.......the first time. The replacement set from eBay (minus that hose, I had bought a new one) blew the left side engine hose. In it's defense it was kinked in the box when I got it. Should have know better than to install it. Apparently the seller didn't think that would hurt anything. Yeah right. TM
Mine is a 2005 XK8 with 34,000 miles +or- a few. Should I worry? My hoses look brand new. It's been kept inside out of the weather since new.
I've been thinking about deleting them altogether, but don't want to deface the car.
Better than loosing it though.

Your hoses are over 10 years old ? It’s the age that matters, the rubber degrades over time, as well as usage, ie mileage.
So, an additional question comes to mind as a result of a different thread, has anyone ever had the aluminum tubing portion of the cooler hose/tubes blow out or break? If so, what were the circumstances and/or contributing factors? Had they ever been repaired prior to the failure? If so, by what means?
A Jaguar independent repair shop owner told me he’s seen the tubing crack right at the crimp location , but I have not seen that personally.
in my case, seeing a drop of oil coming out of the metal / hose junction didnt set off immediate alarm bells for me (stupid me) and a couple of days later it had degraded the rubber hose to the point where the hose just tore wide open and I lost 8 quarts of brand new
Mobil 1 in less than 4 miles.
People say it's the age but I hade the original oil cooler hoses on my MGB GT that is now sold and those where over 40 years old. They still looked pretty good and didn't fail at at least. Hard to tell if it was leaking or not though as those engines are known to leak so much oil it coated everything in oil, helps prevent rust though.
I just relied on the 10 year benchmark since it was the consensus of the forum that hoses over that age were a risky bet. Seems reasonable.
Aa search of the forum does reveal a good number of hose failure horror stories. So far my engine seems no worse for the experience. I shut it off two or three seconds after the oil pressure light came on. But it seemed like hours. My oil pressure, subsequent to the incident, is still very good . The minimum is 25 psi at idle with hot oil (Mobil 1 0w-40) and is normally 75 psi at 2,500 rpm or higher.
If its an electric gauge I would no trust it to be accurate
I am with you 100%. I always prefer a mechanical gauge whenever possible . I did put my mechanical shop oil pressure kit gauge on the car after installing the new hose set. It matched the electric gauge pretty closely.
However, I will be swapping the current gauge out for a full sweep gauge in the near future. Aside from being more accurate, the AutoMeter full sweep electric gauges have a better sending unit and are easier to read at a glance.
Of course, the full sweep electric gauge is pricier, but does have a programmable red light and audio alarm which both activate when when the oil pressure drops below a user-set level.
If your oil cooler hose blew, which one was it ?
