Steve is right on mark. His Rennsport Systems does it correctly.

As I said above, “rebuilding” an engine with all new parts is easy – still it requires skill and knowledge.

The problem is that almost no one wants to afford a rebuild with ALL new parts. The “art” of rebuilding is the cost-effective balance between replacing everything in sight and the criminally negligent by some who specialize in advertising and BS.

So … how do you tell what level of “rebuild” someone is claiming? Clearly some are honest, competent, and skilled rebuilders – including Dealers, independent shops and DIY. We also know there are others.

The reputation of the builder tells a lot. The parts list gives a good indication of the thoroughness of a rebuild. Important is the documentation of the critical engine dimensions.

I think the term “rebuild” has to do with what is necessary to return the engine to reasonably like-new condition. In most situations the builder can better the original Porsche build because of 30-40 years of hindsight and improvements. Just as the original engineering is a compromise between competing engineering & cost aspects, so is any “rebuild”.

We seldom hear about the gazillion of proper and successful rebuilds. Everyone goes home happy. It is the failures that catch our attention. It is very worthwhile to examine these failures.

I think it instructive to examine every failed situation. This allows both the customer and builder (even if the same with DIY) to learn and realize how to improve the situation.

To end on a positive note, with good communication on the Forum, almost anyone can have a successful experience.

Best,
