How many of us have not changed the IMS

[Jgkram]

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

[DrCactus]

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

[BXTRBRU]

03 2.7 59K original

[Benitom]

98 Boxster 66K - No IMS

[clickman]

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?

[navair]

'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

Original IMS

NO ISSUES

[Perfectlap]

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?"

[heliguy]

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

[Tom Mohr]

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

[j.fro]

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

[Boxtaboy]

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

[dghii]

00S 133K miles = No

[kk2002s]

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.

97 Tip, 26,000, original.

[RandallNeighbour]

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........
