1) No. But expect to pay more to have it trued up at a qualified machine shop. It is a desirable item as it is lighter then the Aluminum cases.

2) I doubt you could find a 'crate' motor. Especially for a '71. Maybe a 2005... The Porsche world is very much NOT like the domestic where you can just drop in a Ford/GM/Other crate motor.

That said, the engine mounting points are very similar from say 66-89 so you can drop in something used fairly easily. Your best bet may be finding a running duplicate 71. After that a running newer engine and make the conversion. After that, a core duplicate 71 that you can rebuild to like new... there are many other variants of the above, but you get the idea.

3) I'm one who thinks the 911 engine should not leak. That said, there are some very common places that do leak oil, but are fairly easy to fix without taking the motor apart. Depends on where your engine is leaking from. Posting some pics here will get a good response on some possible culprits for your individual case. I just re-built my '82 3.0 and have no leaks. I do not expect it will be leaking anything in the next 10+ years. The sealants we have to day and the techniques espoused on this board and in Wayne's book will lead to a no-leak engine...

4) Buy Wayne's book to at least educate yourself on what the process is and how you should be communicating with your shop of choice. It will give you a great primer on the choices you may have to make in the future.

BTW, where are you located? If you put it in your profile and you can ask for some good local shop recommendations.
