Hey Steve - nice about the turbo, and regarding the oil leak, remove the lower rocker cover and see if one of the rocker arm shafts has walked in it's bore (take a pic and post it) - when that happens, oil leaks past it and and if it walks enough, you will start to hear increased "tapping" noise (like you mentioned). It would be a good idea to check that before you run the engine much more.

If you do a search for "walking rocker arm shafts", especially in the 911 and engine building forums, you'll find many threads on the subject (with plenty of pics).
