you are putting words in his mouth.

He said he'd not do it because he has a reputation to protect and the probability of other possible failures could cloud the view of his one fix. Look how many misdiagnosed problems you see on the net forums and I, at least, think that a reasonable view from a business perspective.

Google him. Spend hours looking around. See how many people are dissatisfied with the services Jake has provided over the years. Compare it to other rebuilders I won't name. Some are all negatives in the first 5 links, but he isn't that I've seen.

There are people who believe in prevention and changing the oil every n number of miles and using a supposedly better oil than Porsche uses. And there are others who don't. And both sides can find examples to support their view.

When asked what I think and how I maintain mine, I tell people. It is my opinion based on all I have read, all I have experienced, and talks with some serious engineers. I don't condemn other viewpoints or approaches...or at least I try not to. One of my most frequent phrases is 'we each have a different tolerance for risk'. And I think for ambiguity and standards of proof.

One of the hardest decisions about any piece of machinery is the decision to prevent, maintain or discard...especially when you have no statistics to back your decision. How many times have I over-maintained a car? Too many to name. I have one sitting in my driveway right now. Do I fix the ABS system on a '94 Mazda? How about the oil leak? Car must be worth $500 but to replace it would cost thousands and so where to repair it and how much to risk?

But I'd rather have a guy who tells me straight up why he won't do the work or won't do the work the way I want it than to trust the yes man and get burned.

And it is his business and reputation...
