From time to time I've talked to Jake, Charles and Ed by phone and email over a 5+ year period. The discussions originated before they were busy and long before there were even a dozen of the now thousands of engines saved by any IMS replacement procedure. They told me when they broke engines testing. They disassembled bearings mid-engine-life to inspect and measure them. They measured oil flow pressures and volumes both at the bearing and at the source before and after. They pulled apart motors that had run a few years and more than a few real-world miles to take measurements. One of their wife's cars was a rolling testbed. They raced their experiments and drove em between home and work. They drove em between the south and the north in all seasons. They asked people with problems to return bearings to them for analysis. They willingly shared with me their findings and gave me permission to publish some of them. They scrapped ideas as not working well enough after measurement. Some ideas were years in the perfecting because their first experiment didn't work so well or caused problems in other areas. Or distribution changes had to occur as experience with first-time installers taught them that the success rate wasn't high enough.
I also talked to (or at least tried to) initiate discussions with the other purveyors of bearing replacements. Listed and linked to them all on my web site. Both US and other continents. Bet you didn't know there is a UK fix and a Spanish one that are different from the US offered ones.
Why was I interested? Well it started when I got tired of answering "Buying a Boxster" questions on the forums individually and wrote a long article on the subject I could link to. Then I started to assemble multiple other pages that would answer commonly asked questions. One of which is "what are the problems". And so I tried to understand ....
