IMS Failure Risk-please help

[Invulgar]

Got over the slipped sleeve issue of my 986 the hard way. Unfortunately, I am being "offered" a low mileage Aug 2006 base 987.What is the risk of an intermediate shaft failure?

I would hate to go out of the proverbial frying pan...

I know all of the 997 2006/2008 engines have the improved/strengthened IMS design. I would imagine the 2006 987 would as well. I have not heard about IMS failures in 06+ engines...

We have. Basically, if you have an M96 of any vintage, there is some element of risk of the IMS failure. Porsche made multiple attempts at rectifying the problem, but only solved it with the introduction of the 9A1 replacement for the M96, which does not have the intermediate shaft....................

Now I have heard of a failure.. :huh:

Thanks for the info JFP......

There have been IMS failures, true. No one knows the probability or how many have happened. Been beat to death as a topic.

Jake Raby has a lot of info and a solution to the problem.

The boxster underwent an overhaul of the crankcase and RMS seal as well as the IMS bearing in mid 2006. The engines after that period were designated M97 rather than M96. With the S its easy to tell , the engine went from 3.2 to 3.4. litres on the 2.7 the difference was a Hp increase. Check the engine codes , if its an M97 then you have a reduced risk as I've yet to hear of any IMS bearing failures on the M97 engine , though RMS leaks (a much lesser concern) do still occur.

And so do the IMS issues; I personally know of two.....................

First of all thank you for the input. Now, where do I look for the engine code?

I've not seen any reports on forums of IMS bearing / shaft failure for the M97 engine (fitted post 2006) where did you see these failures JFP , what were the failures , shaft or bearing ? ?

Both were customer's cars, both appeared to be IMS bearing failures that led to other destruction; very similar to the earlier cars. One was under warranty, the other was not. Basically, if your engine has an IMS, you are at some level of risk; I have no knowledge of if the later cars fail any less or more, but they do fail.

There is a reason why the new 9A1 is a “shaft-less” design engine……………….
