My next question was answered in your website, the LN retrofit is rated for 50,000 miles, which means I can look forward to another replacement in about 3 years 
I think when the time comes, I'll return to the stock Porsche bearing with the improved seal. It seems to me that relying on splash lubrication in a part of the engine which was never originally designed for splash lubrication will have a lot of variability, like your driving style. Mine is a daily driver highway cruiser, which is probably the worst scenario for lubricating the bearing. You really need to "drive it like you stole it" for the best lubrication. I can imagine explaining that to a police officer, "Just lubricating my bearings, officer!" lol |
There is no "stock Porsche bearing"... Never has been, never will be.
My development of the IMS Retrofit included engines that saw nothing but idle speed for several hundred hours. At idle speed the bearing sees more than enough splash lube, even with idle being the highest load the bearing sees, ever.
The record is an engine idling for 265 hours straight without being shut off at all. Then it came apart and was reviewed.. Then reinstalled and ran wide open for 4 solid hours, so long that the exhaust bolts broke in half and fell onto the dyno.
You don't need to drive it like you stole it for the bearing to live with splash lube. Quit listening to people who don't understand the topic they are writing about.
