How many of us have not changed the IMS
 

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

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 😐

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

74K original IMS (as far as I know)

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... :)

78,xxx with the original IMS. When it is time for the clutch, I'll do it.

101,000 KM and all original, no plan on changing it either.

77500 km (~48k miles) so far without changing the IMS bearing. Since mine is a 2.5 -99 and had a dual row bearing from the factory, I don't plan on changing it anytime soon.

102000 miles including 10000 miles this year. Not changed and no plans to do so.

52k Miles
 

I did change mine when a new clutch pressure plate was needed but the original single row small bearing showed NO signs of wear.

93,000 KM and have not changed my IMS.... if it's not broke - ... you know the rest!

03 2.7 59K original

98 Boxster 66K - No IMS

130,000 km on original IMS and clutch. I will likely do the LN bearing when I do the clutch, but who knows when that will be?

'02 S, 81K miles, no IMS change. I beat it like it owes me money, autocrossed mucho, keep it at or above 3000 RPM. Someday when it needs a clutch I suppose.

2001 Model S with 38+Miles have not and don't intend to anytime soon change the IMS

+16 years
~ 55k km

Original IMS

NO ISSUES :cheers:

After 14 years of owning this car most of that time being on this forum it's my opinion that all mileage is not equal when it comes to this issue. If the miles were from daily driving where not-IMS-friendly contaminants are regularly burned off and the car is not left parked sitting in this stew, the better.

If the mileage is mostly from long stints with long periods of sitting parked with long oil change intervals...not better.

One forum member here had over 300k miles but daily drove the car for more than an hour obviously and maintained a strict oil change regiment. He said "what's an IMS?"

I never changed mine. 111,000 miles before the motor blew (not IMS related). My mechanic said the IMS was pristine.

1999 with 55k, have owned it for 5 months and it has not been changed.

2000 S with 188,000 miles. Owned since 2006 (60,000 miles at purchase). Heavily modded and autocrossed regularly. Original dual row IMS.

01 986. Original IMS. 73k miles. Oil change every 2 yrs.

00S 133K miles = No

95k+ miles, still on original. The bad one, single row 2002. I have started to see a few drops at the infamous motor/trans joint since last winter's oil change, only after I drive it for distance. I think it's RMS.
So would one be an utter fool to just change RMS and clutch???
I am to much of a perfectionist not to take advantage of the trans drop and change out the IMSB at the same time

1999 base with 62,000 miles on a replacement engine. (replaced in 2003) I'm not sure if I have a double or single row bearing. I had the clutch replaced 20,000 miles ago along with the RMS and IMS cover only with the updated version. If I ever need the clutch replaced again I will probably get the IMS bearing done at the same time, but will replace it with the Pelican Parts version.

Here's a Poll on IMS done not too long ago.
http://986forum.com/forums/boxster-general-discussions/65466-survey-failed-ims-replacements.html

97 Tip, 26,000, original.

37k on the replacement motor put in the car weeks before I purchased it without an IMS change.

I drive it like I stole it too. Every single time I take the car out of the garage.

I have decided that life is short and I am going to drive a Porsche like a Porsche and not worry about what might fail.

Hey, if I can get the motor to implode one way or another, I have an excuse to put a big Chevy V8 in it and start street racing doctors in turbos!

My Cousin has a base 1999 with ~ 90k miles. The only thing he has done was pay the dealer to tweak the top when it was out of sync. He has never visited this nor any other Boxster Forum and couldn't care less, He just drives it.

I wish I had his non-interest perspective. I replaced the IMS bearing (on my old 2002 Boxster S) at ~ 30k and the original was as tight as a drum, no pending issues whatsoever. I read, I freaked, I reacted and spent money I should not of, live and learn........:cheers:
