Fraz Posted 21July, 2017 Report Share Posted 21July, 2017 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.http://www.pelicanparts.com/techarticles/Porsche-996-997-Carrera/14-ENGINE-IMS_Bearing/14-ENGINE-IMS_Bearing.htm Link to comment Share on other sites More sharing options...
D2000 Posted 21July, 2017 Report Share Posted 21July, 2017 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 Link to comment Share on other sites More sharing options...
firstone Posted 21July, 2017 Report Share Posted 21July, 2017 The article's I've read lead me to the conclusion that it has a safe working life depending on which one you use how long that is. Link to comment Share on other sites More sharing options...
Russ Posted 21July, 2017 Report Share Posted 21July, 2017 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)https://lnengineering.com/products/ims-bearing-retrofit-kits-for-porsche-m96-97-engines/ims-solution.html Link to comment Share on other sites More sharing options...
Simonk Posted 26July, 2017 Report Share Posted 26July, 2017 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.

Russ Posted 26July, 2017 Report Share Posted 26July, 2017 some of their kits do, the solution is for the lifetime of the vehicle Link to comment Share on other sites More sharing options...
Pokiou Posted 27July, 2017 Report Share Posted 27July, 2017 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.

Simonk Posted 27July, 2017 Report Share Posted 27July, 2017 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.IMG_2533 by RR Films, on Flickr Link to comment Share on other sites More sharing options...
TrevMcRev Posted 27July, 2017 Report Share Posted 27July, 2017 This one is worth doing some research on too.https://tunersmall.com/product/ims-bearing-direct-oil-feed-dof-lubrication-kit-m96-trsdof9705/http://www.pedrosgarage.com/Site_2/TechnoFix_DOF.htmlDeveloped 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! Link to comment Share on other sites More sharing options...
D2000 Posted 27July, 2017 Report Share Posted 27July, 2017 Some say, just popping the front seal off the bearing does the trick though and costs ya nothing!nothing but labour! Which is a fair component of the cost unless like you the clutch is being done at the same time Link to comment Share on other sites More sharing options...

80XTR Posted 3August, 2017 Report Share Posted 3August, 2017 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).

D2000 Posted 10August, 2017 Report Share Posted 10August, 2017 Well done.

Wonder what the warranty is with Porsche and claimed service interval between bearings. Link to comment Share on other sites More sharing options...
