Leak Free Type IV, Pipe Dream? Options

[thomasotten]

I was replacing a motor mount on my engine as I prepare to stab it back into the car. I got my hands full of oily grease crap. It just got me wondering about the possibility of a "leak free" motor. I started to look for leaks, and you know my engine didn't have any dripping leaks, it just gets coated with oil nevertheless. I know the real gushers are the pushrod tubes seals, and the oil cooler seals. But mine are fine, and my car doesn't drip any large amounts of oil. Obviously I have a small leak (or several leaks) that cause the engine, and engine compartment to get coated with gunk. Why the heck are these engines so dirty?

As I start to consider rebuilding, I want to know if it is possible to build the engine so it doens't leak. Period. Any tips?

I will be selling all my selants in a kit soon that goes over in depth where we use them and how to prepare the surfaces.

How soon? I want to build this engine ONCE and never have to do anything but regular maintenance to it after that! (Which is why I'm also anxiously waiting for the results of your next round of lifter tests!)
