Picked up this 1st gen and noticed it has a broken oil pan bolt.. what are my options here? Thank you in advance.

 

Doesn't look to be causing a leak. Probably best to leave it. Some of the oil pan rail bolt holes are through holes but that one is blind. Removal would involve a left handed drill bit and some luck. If the pan has been off once or twice, the threads are probably gummed up with bits of silicone.

I recommend leaving it as it. If the engine comes out in the future, fix it then.
