Suggestion

Trust that it would have been WORSE if you were using "additional oiling", thereby force feeding the IMSB with debris filled oil.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I know the general consensus is that the LN bearing is the "end all" for the IMS bearing fix. Having just had my "new to me" motor turn to a big paperweight after not even 500 track miles (not bearing related but something internal - unknown at this time), and feeling the condition of the bearing during initial tear down, I'm beginning to think that the LN is no better than any other without the additional aid of oiling (it spun rough). This unit has more bearing surface and has two additional aids to keep it wet while in use. I'm also going accusump this time in addition to the new bearing on another "new to me" motor. May also do the X51 style pan baffle.......not doing a 3rd motor!!!! Just curious if anyone has used it or knows someone who has? Comments, concerns? Thanks EDIT: Not sure where link went when I posted this last night http://www.****************************************.com/ShowItem/294103%20IMS%20Intermediate%20Shaft%20Bearing%20Up grade%20Eternal%20Fix.aspx

POST 2Original post

If you want a bearing that will last, install LN's IMS Solution in your single row car. It's a plain bearing and it won't collapse as ball bearing designs can when they fail. You're second best choice may be LN's Gen 2 bearing. It provides the load carrying capacity of a dual row bearing.

POST 4Original post

Your "other internal failure" is what created that. If something else goes south in the engine, ANY of the retrofits out there will suffer from the occurrence. Trust that it would have been WORSE if you were using "additional oiling", thereby force feeding the IMSB with debris filled oil. Your "fixes" that are mentioned will not solve the root of the issues that led to your most recent failure. You haven't touched on the underlying condition that is always present, but don't feel bad, few people do. You may do a 3rd engine, whether you want to, or not.

POST 5Original post

Sorry to hear about what you are dealing with OP, pricewise anyway :/ sux Lot can go wrong with anything mechanical, not just bearings Now time to get something better, fun ahead! Cheer up bro

POST 6 / ORIGINAL POSTEROriginal post

Okay, I'll bite, so what is the "root" cause of my "other internal failure"? What's the underlying condition.........other than it's not a properly engineered and built 911 aircooled engine
