Autoweek Words on IMS

[Trey T]

I agree but I would NOT recommend people to use the LNE or Pelican retrofit. Those are just as good (or bad) as the OEM. Pelican nor LNE makes no guaranteed of performance, according to their websites; who would, right? Remember OEM IMSB have been reported with >100K miles by many.

I believe the DOF could be a very good solution.

And if you want an early warning, the aftermarket has that covered to with the LNE's Guardian that goes on your dash. Worrying about is unecessary because this is one failure that you can actually do something about.

arguable. In the 3-4 years since the aftermarket options have become available, and across the various Porsche forums, I can't recall a single person who did the upgrade and came back to report an engine failure. Not a single one. In fact, I'm not sure I can think of any other product that you can buy for a Porsche today that never had a person post a complaint after the job was done. Neither Pelican nor LNE.

Point is to take the orginal one out at some point, sooner if its the single bearing unit. And with most things in Porsche world, if you have to replace a known weak spot, replace it with something better and in the case of the LNE unit it is in fact a much better spec'd unit over stock. Even if the bearing is not the root cause of the issue its still a critical engine component that should show signs of development, not unlike your coolant cap. And if you go with the LNE Solution, you remove ball bearings from the equation entirely which pretty much means you never have to service the bearing or need to worry about oil feed issues ever again. Sure its expensive but welcome to Porsche world where parts are expensive on the following days: M-F, Saturday and Sundays.

There have been 0 reported LN dual row bearing failures to date and perhaps 5 single row ones over thousands of installations. That is a completely different track record than the track record of the OEM beating.
