Depends if it is just the bearing replaced in which case you would consider a change with clutch for caution.

I pulled my IMS out of a perfectly running 2002 Boxster S (3.2) with 140K and the bearing looked perfect.
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.

A mate of mine bought a 996 with 120k on the clock
the IMS bearing was done about 70k ago, does it need to be replaced again or the process kind of once in a life time?
thanks
Been doing bit of reading on 996s of late, from what I can gather it should be done at the same time as a clutch.
Great info here.

Depends if it is just the bearing replaced in which case you would consider a change with clutch for caution. If the ims solution was done it should not need replacement
I'm about to buy a 996 3.6, and i'm going to go with the LN Engineering IMS Solution - mainly because after that I'll never have to think/worry about it again. it's a fair bit of money just for a bearing replacement and oil line (but cheaper than an engine rebuild)

Find out which LN Engineering bearing it is and check their website for the recommended replacement period. There has been an updated version in recent years of one of the options. Yes, the LN Engineering bearings need to be replaced at some point.
IMS... IMS...... ok, so it comes down to the cars age and how its lived its life. If its been a garage queen and rarely driven and never pushed, i would change it with every clutch. If you have a original dual row bearing i would leave it. Rock solid. I know it sound stupid but a lot of the IMS issues occur due to the way the car gets used and how well its up keep and service has been done.
Take that with a grain of Salt. I know i wont be replacing my IMS anytime soon. At every oil change you should open the filter up and see if there is any metal shavings to see what the condition of the engine is. Should give you an indication on the internal condition and you can move from there.
Good luck, cause the 996 is an amazing car to drive and own. IMS is an addressable fix.
Here's my original dual row... All theories aside, I'd just do it, but then again, I ducked a $30k hit by replacing mine.

This one is worth doing some research on too.

Developed by guys racing Spec Boxsters in the US and suits 986, 996, & 987, 997.
I were just going to thrash the BoxRod as is and splash that oil around, but it needs a clutch so might as well do it...
Some say, just popping the front seal off the bearing does the trick though and costs ya nothing!
I pulled my IMS out of a perfectly running 2002 Boxster S (3.2) with 140K and the bearing looked perfect. Nothing wrong with it and didn't show any signs of wear or failure. I still replaced it with the EPS Roller and process was no harder than a clutch replacement. If you've got the room, tools and time, I'd encourage you to give it a try yourself. Only cost me $1000 for parts including loan locking toolkit that I've still got (happy to loan to people if they wish). You can read about my journey here if you're interested

Someone is selling the removal tool (together with an RMS) on ebay if any of the DIYers are interested:

Looks like Porsche now has its own IMS retrofit:

otherwise not a very useful article and does not seem to appreciate the distinction between LN’s retrofit kit and its solution
