There are lots of places to leak oil. While warranting a previous repair would be a nice thing, I always like to point out that previous repair analysis is poor diagnostics.

My approach no matter who is responsible is to find the source of the problem. i always chuckle at the calls where the customer starts by telling me the car is doing the same thing it was last time. Yea it is broke. To the person behind the wheel being broke looks the same. They proceed to waste ten minutes telling me about their last repair.

History does have value to dislodge underlieing causes, but what is wrong now will not be any easier to diagnose by narrowing ones quest in a non technical discussion. Another similarly funny discussion is where I get told what to check because that is what they can afford, barrel of laughs. Problems are where you find them! Convenience or responsibility form no usefull part in diagnostics.

My suggestion would be to have the problem professionally evaluated to be sure you don't cause further damage to non warranteed concerns by the long drive home.
