Storage question

[DWBOX2000]

I just happened to come across Pedro's IMS push for his bearing yesterday. It was pretty informative. I am not an engineer so don't know what is true and not true. Seemed to make sense. He was talking about cars that sit more having more problems than cars that dont. Then he said when a car is sitting (engine not running) the bottom of the IMS bearing is sitting in oil. Over time this oil seeps through the seal and somehow ends up in the IMS where bad things start to occur. I got to thinking, if this is the case; why not store the cars with the oil a bit low so it is below the seal. Just get up to level when the spring comes? There is likely a reason and I am just curious why? What else is sitting in the oil at the storage level. Please advise.

Don't want to think about winter so early considering it just ended, just for future reference. Thanks.

The factory IMS bearing was designed to sit in oil, bad thing start to occur when the seal hardens and shrinks.

As for Pedro, he is counting on you thinking things seeming to make sense...………..

Thanks JFP.

I got the LN retrofit a couple years ago. In your opinion, is that seal better than the stock or just the same?

No issues 5k later.

The LN bearing uses an "open" rear seal, designed to allow oil mist to enter an lubricate/cool the bearing.

I think if you want to know what Pedro thinks, you should ask him. Although he does check in here occasionally, he answers his email or phone regularly. Just go to his website Pedro’s Garage.

Pedro is also the moderator for Boxster/Cayman Tech Questions on the PCA site. Great source of information and he is overwhelmingly generous with his time and an honest opinion.

Anyone checked this out? Would that be a permanent fix? https://www.ebay.com/itm/Porsche-IMS-Intermediate-Shaft-Bearing-Repair-ETERNAL-FIX-Retrofit-w-Oil-Feed/173827551486?_trkparms=aid%3D111001%26algo%3DREC.S EED%26ao%3D1%26asc%3D20160908131621%26meid%3De754d 61847d848fe80b4433b054d9662%26pid%3D100678%26rk%3D 3%26rkt%3D4%26mehot%3Dlo%26sd%3D282858137387%26itm %3D173827551486&_trksid=p2481888.c100678.m3607&_trkparms=pageci%3Aa33ab470-6df1-11e9-b447-74dbd1803bed%7Cparentrq%3A7fc8b22516a0a9c9a157229c fff82b8f%7Ciid%3A1

Thanks for the info. I'll check it out.

I guess in my case, I don't have a seal so I just need to keep the oil relatively clean. Change every 3k or 1 year.
