Who HASN'T done the IMS Retrofit (and why not)?

1) I don't fix what's not broken
2) I don't normally get easily influenced by those in the business of changing parts
3) I follow official reports and figures - in this case they are very low, or still non-existent
4) I couldn't care less even if the car itself would blow up, I'd get another one tomorrow
5) A car is for driving, and life is for living


I've not rebuilt, nor do I lay awake at night worrying about it. Madmods said it best.

This is my 6th summer with my Boxster... I have 70k miles (had 30k when I bought it) and I don't worry about it. I drive it like its supposed to be driven. So far my oil filers are clean of metal debris If it happens, it happens... I'll deal with it if and when that time comes. If I need a clutch at any point I would probably do it though...

[ProjectM96]

I am at 86,000 miles in my 2000 Box. Haven't done the IMS and don't plan to anytime soon. I also drive my car like its meant to be driven. Always revving high, turning fast, accelerating as fast as I can each time I drive it. When I did oil change at 80k, the oil filter had no debris.

Plus, I hear the IMS issue is due to maunfacturing tolerances problems. Some were not in the correct tolerances and some were. It's impossible that all Boxsters were effected.

unless you're already in there and/or have lots of disposable income.

I do have the double-row IMS bearing sitting here however. Been here for the last 12 months or so. I was waiting for a valid reason to drop the tranny so I can fit it. However plan changed after confirming a severe cam deviation (-3 degree in less than 15k) in an engine with less than 70k, and other little things which (for my taste) clearly show that this is not one of those perfectly manufactured motor!

I'm at the stage where I do not know whether I should drop the the 2.5L and rebuilt it myself (as a hobby... love gasket kits!) -OR- just enjoy it until it blows up and then mount a 3.4L fully rebuilt engine.

Car stories for you brotha. Good luck with yours!

Yes I agree 100% with this. I have weakened and had installed the IMS Guardian though. PPI said fine oil mist on rear of engine and bell housing. Is that a ploy to get me to install new RMS, ims job and new clutch while in there? When the Guardian warning goes off , then a new IMS. Otherwise I drive my 2001 Boxster base hard when conditions permit. Good post. Great thoughts.

I have been wondering about this "When the Guardian warning goes off"... doesn't that mean that it's already too late ? Bits of metal floating around in your sump means quite a bit of damage has been done already surely ?

Yes Terry I understand your question. I think that LN engineering has done enough research to show that the detection of metal buildup is occurring before an actual IMS disintegration. The makers have way better explanations than this layperson. For me it is a form of insurance. When the warning horn/lite goes on pull over asap.

I have spent $2k on my 2001 Boxster last year and assuming nothing goes wrong, I am only spending minimal on real Porsche coolant this year.

[j.fro]

I bought my 2000 Box S in Feb 06 and it had 60,000 miles. I'm now at 152,xxx. Last year at 142,000 I had to pull the trans to fix the second gear synchros, so I had a nice look at the back of the engine. The RMS had a well established but dry velveting, so I left that alone. The IMS was dry as a bone. 140,000 miles of dirt, but no signs of oil.
With this many miles and five years of hard autocrossing, the engine doesn't owe me anything. When the time comes, she'll be rebuilt to add some serious power, and then I'll do the bearing, along with everything else.

[97 Boxster]

I have had my 97 for 3 years now and it has 82k on the clock. Its a 5 speed and it still feels solid. I drive it daily and I maintain via oil changes and any other necessary repairs. If it goes, it goes and I will then repair it. 3 years of pleasureable driving will not make me change how i feel. Hope it doesnt happen but if it does, then it does.

+1 for Madmods.

The only thing I'd add is that if my IMSB has lasted 104,000 miles, then its likely to last quite a bit longer. My theory is to redline often to splash some fresh oil into the failed IMSB seal!

Boxster 986 Complete Suspension Overhaul

And all this time I thought you were like me...fix EVERYTHING that is not broken...because it is fun! Just messin with you.

Oh and I'll be giving an update to that thread...since I to developed suspension overhaul fever.

And yes I DID change out my perfectly good IMS double row

[Dave S.]

I haven't upgraded the IMSB in my 2003 S (24k miles). Seems spending $3K + on an insurance policy that you don't know if you need seems pretty steep on a $20,000 car.
If it fails, I'll either sell the dead carcass for a few thousand and never buy another Porsche again, or maybe take advantage of the situation and try to find someone with experience installing a 3.8L 997S engine into it and make it a rocket.
If I ever have the transmission out and am replacing the clutch, I would probably do the IMSB for good measure, just not willing to spend that much for nothing in hope that I'm fixing a problem.

[rdc8118]

I've got a 99 boxster with two major accidents under it's belt.
Resale values on old boxsters are low and mine's even lower. If i needed a clutch then I'd spend the extra cash and replace it. For now I'll just do frequent checks on the oil filter with a high power magnet (I pulled out of an old hard drive).

After some research, I discovered that it doesn't have to cost 3K to do the IMS upgrade. In fact, for low mileage vehicles such as yours and mine that probably don't require any clutch work, , with the right "indy" the service can be performed for under 2K . Not bad for something that will not only protect your investment, but give you a piece of mind as well .

mine was $1900 including RMS and oil change. My clutch looked like brand new, I should have done the flywheel, going to have to do that within the next year after the shop showed me pictures of it and I have a very slight amount of clutch chatter.

good news was the shop gave my car a clean bill of health after the IMS (besides the flywheel)

Im going to be out of town to a beautiful southwest asia resort for the next 9 months so I did not want to take any chances since my wife will be driving the car some while I am gone.
