Routine Preventative Maintenance

Is he an expert on the M96, without a doubt, certainly one of the top in the world, maybe #1. Still it seams that its all about failures, not the vast majority that don't fail and never will fail.

I would think that he does have the data on what will cause failures and what PM most likely will prevent failure (other than replacement)

you've got five posts into this forum and you want to start an argument already?

One thing you should know about this forum is that we steer clear of pissing contests. In fact, it may be the only Porsche forum I've been to where there isn't a daily drama.

While I may not have many posts, that does not mean I have not read a lot of the threads.

I'm not trying to start an argument at all. I'm just calling them as I see them.
The fact is, he has an extreme amount of knowledge on the M96 and I just can't believe that all is bad with the engine. Porsche has shipped 100's of thousands of them in various forms and they all will self destruct?

I am just asking a question that I guess too many are afraid to ask.

He is an expert, but IMHO, he almost always see's the glass as half empty and focuses on fear and and destruction. Lets fact facts, he does profit from repairing and building motors. I'm not saying that is a bad thing nor is he not entitled to profit from his knowledge and research. Very much the contrary.

I agree...EVERYONE of these engines will not crater. I thought I heard numbers like 1%, to 5%? depending upon the year and engine...as an engineer...I love finding the REAL relationship of data associated with engine failure...I have the utmost respect for Jake. So, I'm not pissing with him...I'd love to know for real the results of a root cause analysis.

We discussed this a couple times here and I even posted, years ago, some of the production numbers from Porsche for the Boxster and we "guesstimated" the number of failures. Given the numbers, in the 100s of 1000s, the actual percentage of cars with the IMS failure is certainly low. Sure many of the dealers and indies I talk to have seen the issue but again, in very low numbers compared to the total number of cars produced. From the top of my head around 160,000 986s were produced. Certainly less than 2% had IMS issues.
The lawsuit/settlement with PCNA will probably show way less claims than that.
I can bet Jake did not work on more than 3,200 engines with IMS failures.

Keep in mind people normally come to forums to discuss problems, and rarely to say how great they had their cars running for 10 years without a single issue.

Jake is indeed a great guy, top notch mechanic/inventor and an authority on M96 engines. One of my buddies attended his class on the engine and was extremely pleased and impressed. That comes from someone that was a Porsche Master mechanic for many years and left to open his own shop.

Don't punch the gift horse in the mouth. By your own admission JR is an expert on our engines why don't you just take his posts for what they're worth.

Fair comment, and Jake does provide information not available many other places. Maybe its his no BS manner

Exactly!

Yes, and as I said before, he may even be the #1 expert

Also, its not just 986 engines, it is some 996 engines as well, so the number of M96's is higher
