IMS tell tale

[algiorda]

Quite simply, this is the same issue we have been facing with other cars for decades with timing belts. It's a maintenance item.

Either you gamble and don't replace it, or prevent engine disruption by being proactive and replacing it before it fails.

While I would love it to be non-existent as an issue, I'm taking the maintenance tack: short oil change intervals (monitor for debris), change bearing with clutch and RMS .... only challenge is that historically clutches seem to last me longer than 20 000 miles ... so ....

What does the clutch lasting 20K miles have to do with anything?

Have you been following the thread?

Clutch job means it's your opportunity to change the RMS and IMS, due to cost effectiveness.

What if you're clutch is still good? What do you do???? What about the children????

"Bridge mean more traffic. More traffic mean more money ..."

sheesh.

Ok, here's my take on it...

There wouldn't have been a class action lawsuit brought against them, and PCNA wouldn't have settled, if there wasn't some merit to the argument that the single row bearings have a higher than acceptable failure rate.

If it worries you, have an LN ceramic bearing installed. Any shop that does it should pre-qualify your engine (by checking for metal debris in the oil filter and sump) before doing it. If they find metal, start sourcing a good used replacement engine or commit to tearing it down and rebuilding it.

If you never want to have to worry about the IMS bearing again, have an IMS solution installed. This will only prevent your engine from going boom from an IMS bearing failure. There are lots of other things that can cause your engine to go boom... (in my case it was a horribly stretched main timing chain which we caught just in time).

Whether it worries you or not, just get out there and drive it ("like you stole it").

JFP has provided more valuable advise on owning and maintaining a Boxster along with Jake Raby and Pedro Bonilla then anyone else on this form, maybe throw in Mike Focke and Macster.

They have the knowledge and facts to back up their opinions because they have worked on 100's if not 1000's of Porsches. I will take their advise over anyone who has owned only one or two Porsches. Their knowledge is empirical, mine and most others on this board are only anecdotal in origin.

Given the length of time that they have been advising, I would not dispute that. It doesn't give one the license to be condescending or disdainful. My original comment was almost rhetorical in nature that if an owner wishes to handle IMS work at the same time as clutch work (many threads here mentioning that as a best practice) that's great, but what if the owner still has a 'perfect' clutch? Then they (the owner) have a decision to make.

If you read a question or comment on a thread (in ANY user forum) that you think is stupid, or pointless or evidence of someone being mentally retarded (to use hyperbole), why answer it? Just move on. If you think that it's all of the above, but you actually wish to help, then ask for clarification. It may be a matter of semantics or other as to why you think that way.

P.S. the "You" is a generalization of a the forum user

Look at your posts, these are from someone on here since all of FEB and you're judging his credibility??? Read your posts and look in a mirror, there is/was only one insulting and acting like a left wing twerp here. You are way overboard and while JFP can certainly handle himself a post like yours leaves me pissed to the point I am compelled to respond. With your attitude here's hoping you end your post count at 89. Enjoy the Cheesecake Factory and lest I forget GFY!!

Lol! Well I think it's clear why some of these cars get vandalized. Smell ya later. You're all class.

Only true for interference engines. For non-interference engines this is not a catastrohic issue, more of an inconvenience. Memories of a 1980 Volvo wagon which ate its timing belt at 30k miles and fortunately suffered no ill effects.

And the timing belt maintenance is in the owners manual when you buy a car. I haven't found the section in my manual where it specifies the interval for replacing the IMS.

Has Porsche ever come out and defined this service interval, or do they just let owners discover it on their own? I don't use the dealership for more than parts -- has anyone ever had a dealer recommend an IMS replacement proactively?

The reason or that is that according to Porsche, you cannot change the IMS without taking the engine apart on any M96 or M97 engine, and as they do not let their techs take engines apart, you simply are billed for a factory replacement engine. Solves their problem, and yours, well, sort of anyway...........
