Today I started to take apart the 400F engine.  Here is what it looked like before starting.

So that was the tag that was on the engine, its a 1975, and it had "70% Leak" written on the tag, but over the top of the 70% was written 30%.  The guy I got it from said that the result of a leak down test was 30%.  I figured either way that was too much, and I wanted to learn something so I was going to take it apart.
