How many of us have not changed the IMS

[Fuzzuki]

I wonder how many of us have not changed the IMS?

[bwdz]

I haven't, 66k miles on my 97 and original IMS and clutch still in there.

100k and original ims. I had a boxster before with 106k that was also on original. No issues with either.

Making me feel better already.

In a racing weekend, I will typically do around 400 shifts near/at redline (every upshift). Then I do this 15 weekends a year; so 6,000 shifts at redline per year. With probably a few over-rev downshifts.

I've done this for two years on a used engine with the original IMS bearing that already had 94,000 miles before I installed it. And its still running great.

Of course, at this level of use something will eventually fail (probably sooner than later) but its amazing what they'll take.

82K and original

Sixteen years with original IMS. I may change it when I do the clutch.

'01 S, 126K miles, original IMS.

I just recently changed mine, with 15 years and 146K on it. (Actually I had it changed by a pro). I pulled the grease seal off, and there was still a tiny amount of grease left in the bearing, so I'm not sure how many more miles it would have gone. After seeing that, I feel that it was a smart decision to change it. Since I had the clutch replaced, it just made sense to replace the IMS bearing.

Those of us that recently purchased our Boxster have no idea 😐 I wish there was a way to find out. Haven't had mine very long but don't plan on replacing.

If the PO had an LN replacement you'd have a little LN authenticity code sticker added somewhere on the door jamb or under the hood.

Yes but not all replacement companies do that do they? For all I know it could have been replaced 6 months ago 😐

74K original IMS (as far as I know)

I've never done it but maybe you could get a periscoping camera down in there for a look?

I just bought mine 03 Boxster 5 spd has little over 71k miles 3 months ago. No service history. Clutch is still solid. No indication IMS bearing was replaced. I do feel uneasy but I will wait till needs clutch to do the IMS bearing. I do rev. up the rpm to 4000 plus when driving car most of the time fear that will lube the INS bearing.

102k, original, and never plan to change it for as long as it's a daily driver.

Don't get caught up in the hype of them failing. It's rare, just go and enjoy it.

Hi there,

Well, I drove my 53 plate S for 176,000 miles from new (most days) before the engine blew last year and never replaced the IMS...

Here's a Poll on IMS done not too long ago.
