I love reading this statement. The more excuses I have to drive the hell out of this 2.7, the better. I haven't hit the rev limiter yet, but I have been about 200 rpms into the red. Unfortunately any red in 3rd gear is way over any posted speed limits.

i have a 97 boxster 2.5 just had it serviceds and it needs the rms doing as it is leaking at 50k miles i have only had the car for 3 months done 2k miles in it plan to drive it as my day to day car once the rms is replaced will this happen agian the car has a full service history and has had the rms done before.

what is the chance of ims happening at 50k miles +

also the drive window sticks some times when openning/shutting the door garage wants to replace the door lock £125 but isnt there a senser they could check first?

love the car but this rms and ims is a bit scary

as for the window, pull the panel and shoot some spray white litium grease on gears and rails. Sometimes the soundproofing gets pulled into the rails or gears also.

For the RMS- mine has been fixed three times. finally it is holding. The RMS just leaks oil and makes a mess. unless it is pouring out or you are doing a clutch anyway, fixing it is not really needed.

As for the IMS- it can go without warning at any time regardless if the RMS is leaking or not. If the RMS or clutch is going to be fixed, it is simplely a matter of 600$ to have the IMS replaced.

The cost of the IMS replacement is in the labor to get there to begin with.

40-60K has been the "sweet spot" for several IMS failures......

Jake Raby and Charles Navarro have been "suggesting" replcement of the IMS at normal clutch replacement intervals (40-50K miles), just to be safe until a larger base of installed units can provide better data. Last I heard, to date, no replacement LN IMS unit has failed in service................

I would like to know what happened to the original car that began this thread. It is too bad that many times, someone pops on to state an issue and then no follow up.

Unfortunately, probably like many other that have had one of these failures, the poster is no longer “part of the family”. More than one individual that has lost an M96 to the IMS while still under warranty immediately traded in/sold the car as soon as they got it back. One guy lost two engines this way, and drove the car with the second warranty replacement directly to another brand dealer the same day and traded it in….. And you can’t really blame them.

Thank you, i purchased the car with 60K miles, i have the 60K service comleted and the shop said overall very good car. i do trust the shop since they have worked on my benz for years. is there a way i can check the IMS to see if it may have been changed or is this require a major disassembly. i would hate to spend 1k if the IMS has already been done?
help if you can
thanks

Unfortunately, the only way to inspect the IMS is to pull the gear box, and then remove the clutch and flywheel. Many Porsche dealers still are telling people that the only way to change the IMS bearing is to split the cases (total disassembly of the engine), even though not just independent shops, but backyarders are pulling them from fully assembled engines and replacing them with the LN unit.

Two things to consider: If the IMS bearing had be upgraded, it would have been a featured selling point when the car was sold; dealerships (in general, as LN has won some converts) would not change the IMS bearing, they would replace the engine.

You can also check with LN Engineering to see if you VIN is listed as having been upgraded…………
