When your oil lines failed where did they leak?

[dstoops]

I'm curious as to where most oil line failures occur. Is it at the engine block end or at the swedged crimps? Did it blow all the oil out at once or just leak until the level was too low?
Thanks

Mine did not fail they were starting to weep at the cooler end crimp connection.

The oil line generaly "Weep" at the crimp connections at the cooler end. If you open a failed line up you will see why they weep. The tubing has a very shallow set of square grooves, .015" or less deep, cut into the tubing and the hose compressed into these shallow groves at only one of the 3 crimps, the other 2 miss all togeather. Over time and temperature changes the oil creeps past this inferior mechanical joint. There is a second cripm at the end of the connection used to keep the hose from blowing off the end of the tube. That crimp would withstand several hundred lbs of pressure but the cripm used to stop a leak will not hold 40 lbs.

The suprizing thing is GM uses the same system for the AC lines and they hold against 300 lbs. of freon an much small molecule than oil.
