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

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.

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.
