Yup! I replace every oil pressure hose every 10 years. Mostly to insure that the fittings don't corrode together. If the cad/zinc plating is good I take the hose to my local hydraulic shop and have new rubber hose sections grafted on. Some hoses have specific lay lines to orient the ends. I don't mess with oil pressure lines. I even replace the "S" supply tube every 5 years or so. Oil lines are easy, engine overhaul due to oil starvation, not so much.

My S line is new! Lol.

The oil lines are on the scavenge side of the system. They are low pressure with oil and air being pumped to the cooler and to the oil tank. Very little stress on the hoses. That end of the crimp has no load in it. That is why the crack survived so long and even corroded. If that portion was removed, the crimp still works.

Point being, the rubber will likely fail before that region.

Its not the pressure, its the weight of the line, oil and force when hitting a pothole or other road irregularity. I can personally attest that plenty of oil will exit any defect in the hose.

Agree. While you're saving up for the inevitable or find a suitable replacement, I'd install a stainless hose clamp around that area to augment the crimp, then pay attention to your oil pressure, but most likely the smoke that results when leaking oil splashes on the exhaust system. Inspect at regular intervals.
