I don't know. It seems like an odd theory about expansion and contraction as the clamps were tight and it held for 10k. I ordered the replacement hose, but it was not the same as the original and since the screw clamps had been holding the shop left it with my makeshift repair. I had the pull the clam again and try to fit the hose (which has 90 degree ends with swivels, not 45 degree as was on the car) and it fit but would rub so I called the place I bought the hose and they are looking into it.
It really ticks me off because it can't be that hard to keep oil in a hose.
The theory I am working on is that there is a sticking valve or thermostat or something that cause a pressure surge which causes the weak point to fail.
OTOH, my other love, Land Rover Defenders, have an issue where the oil cooler lines are too close to the exhaust manifold and when they fail over time it ends up causing engine fires. There was a poll and nearly everyone with original lines had a failure and it was 50%/50% on whether there was a fire.
I just hope the engine is ok this time. While the used engine was not that much money the first go around, it was NOT a fun job to put it in and I really don't want to pay a shop this time, but given my work schedule, I probably will have to if I want to drive it this summer.
