What is the name/manufacture of the sin bearing?

epapp.... shortish fuses maybe but......

Over the last 40 years working in Engineering around the world I've been associated with some very smart guys - BSc's, MSc's and Dr's, Hons grads etc, etc. Most of these young guns thought they were Gods Gift to the Engineering World As We Know It, but that mindset only lasted a couple of years after graduation & reality kicked in - sometimes you have to put aside the theory and look at the problem from a wholly realistic & practical view based on years of hands on analysis. Many a humble shop Foreman has outwitted his new Grad Eng on the practicalities of life.

Now I agree that new ideas from keen minds are the stuff of dreams, but remember that some people have been at the IMS coal face for over 10 years, pioneering solutions that have saved us mere mortals a whole wad of money with their combined expertise, knowledge and commitment. Flat 6's Jake Raby, LN Engineering's Charles Navaro and Hartech's Barry Hart are no fools and have earned their spurs the hard way. To say that you are going to add "some real engineering" to the IMS problem (which by the way, they were working on when you were probably still going through puberty) is going to be very interesting.

I for one am looking forward to your revelation regarding a new course of action - the Epapp Solution (Pappsolution) perhaps ...........

But the failure rate of those other parts you mentioned seem to me to have a much lower probability of failure when compared to the IMSB. Sure cam chains can break, and the IMSG will probably pick up on the metal fragments and alert you, but my quest is to solve the issue of unknown IMSB health given my cam chains will probably be fine for the life of the engine (probably just jinxed myself).

Not so much. I currently have failed engines in my facility from 23 states & 3 Canadian provinces, and they came to me in their respective Porsches shipped from all over North America.

Of those TWO of them are here for failed IMS Bearings. The rest are here for one of the other 24 modes of failure. In the last 6 weeks we have seen 4 broken timing chains and have caught one more that was in the process of failing and was discovered while qualifying an engine for an IMS Solution retrofit procedure.

The reason why more of the other failures occur today and less IMSB failures is primarily because more engines have been proactively retrofitted. Another reason is because the other issues have always been there and because we have always seen them, they just haven't been highlighted like the IMSB issue. When I have tried to share this I was just blacklisted as a "fear monger" for exposing this. I pulled those details off the site because I got tired of it. The jobs find us, no matter what.

Concerning "real Engineering", well there's always more than one way to achieve the same end result. Some are better than others and some are overly complicated. Simplicity drives my personal developments. The component that isn't there, can't fail. Thats why the IMS Solution eliminates 11 wear components found within the OEM single row IMSB.
