Completely remove one subframe bolt at a time, then put it back in 5-6 threads. Do this for all four. This will lower the subframe about 2". Next, use a jack and some wood on the motor mount arms so that you can raise the engine. You should be able to raise it about 2" which will give you enough space to remove the oil pan.
Take the hood off, hook the front of the motor, start lifting so theres a wee bit of tension on the chain, unbolt the motor mounts and see if you can lift the motor enough to take the pan out, if you can't then lower the subframe and she should come out then.
