Any pictures of the mess? Just curious. That seems like premature cracking for a relatively new part.
 
After this happened the responses are that it is common. Moto Guzzi apparently contracted with a vender who used the wrong materials for this application. Check yours....it happens fast, at least for me
 
I just fixed mine yesterday. Both sides were cracked on my Norge. The left side was leaking all over the place and the right just started. For a quick, easy fix I just cut the ends off and reattached them using new clamps. I have 36,000 km.
I found the leak while setting my valve clearances. That job was overdue.
 
Not sure at all of which oil tubes were cracked. Are they on this diagram? If so, which Number(s) are they?

Thanks,

'Geezer

Mine were cracked and leaking at 3000 miles. Replaced with new hoses ordered from AF1 and sleeved the new hoses with heat shrink tubing. So far no leaks or visible cracks at 35,600 miles.
