Rear oil pan bolt snapped

Was going through and snugging up my oil pan bolts and the last one I did snapped. It is one of the two long rear ones (driver side, closest to oil filter). Is it possible to use some easy-out drill bits to get the rest of the bolt out, or since it bolts to the bottom of the rear main seal, will I be needing to drop the transmission in order to get it out? It snapped about a quarter inch up the threaded part of the bolt, so if I don't get the rest of the broken bolt out I'm thinking I could get another one and cut it down to that size and put that on in for at least some support??

Also, I drove it around the block and parked it. It doesn't seem to be leaking. Am I fine still using it as my daily driver, so long as there is no leaking?

now that there is no tension on the threads you might be able to use a pick or something and spin it out.

if you are good with an e-z out then you should be able to get it. If you want to leave the bolt that way that it is just keep an eye out for signs of leaking and get it fixed if it does.

Where was your torque wrench and torque specs? Those back 2 bolts take way less torque than the rest. You're working on a high tech all aluminum motor. You NEED torque specs and a good torque wrench to keep from breaking bolts and stripping threads.
