Install the oil / air seperator like Matt said, clean the MAS with MAF sensor cleaner, and fix the damned vacuum leak. Problem solved. You're seriously making this out to be a ****load harder than it really is. This is about as basic as you can get as far as problems. On the "difficulty" scale it ranks right up there with changing oil or spak plugs.

If the engine was recently rebuilt, check teh compression to make sure someone didnt **** something up. If they did, then rebuild. if it's fine after doing the three things listed above, then that's the end of that. It's really not that hard.
