Yes, I just charge up Euclid and enjoy the views.

I have 127K on my car with the original IMSB. I'm not worried about it with this many miles on the engine. I'll drive it like it is until the engine or IMSB fails and get me a low mile engine and do the IMSB at that point. I love this car, it's in perfect condition. I don't know what Porsche did to protect these cars against rust, but there is zero rust on the body of my car, even the bottom side. It's like you could keep putting engines in the car for 30 years and it would still be like a new car.

I have parts sitting here that I've had for over a year and just have not got around to installing them. I have the complete 911 (996) gauge cluster to go in it, new KONI FSD struts/shocks and 1" lowering springs, plus new bits for the suspension. Still got my eye on getting the O.Z. Alleggerita HLT wheels and they have them in gloss black now. Lots of fun and life left in this wonderfully balanced car.

I've never owned any vehicle as long as I have owned this car. Unless the car gets wiped out in an accident, the title of this car will be in my name til the day I die.

not all 2001 have the single row some of them have the dual row installed, you just never know

Here's what I don't get about those who want to run away from the whole IMSB thing...Given the bias most of us share is the pure pleasure of working on our cars, what is so different about the IMSB? We swap motors, do clutches, talk to our cars with our laptops etc. Why is the IMSB so different? It seems like just a weak point in an otherwise excellent mid-engine sports car. You do not even have to remove the engine and the multitude of available fixes, videos etc. should make it a perfect DIY project.

I don't think anyone is running away from it as an issue, but if you have been on this forum for a while the majority of new user at some point will post something like, "I just bought a 986, I'm super excited, but I heard about IMS should I be worried?" It's tiring and annoying, and got old several years ago. I agree with the other posts that called the IMS fix a job you might consider if you are "already in there," but not something you need to rush out and do immediately.

Although I’ve worked on cars for years, I am new to the guitar. Fortunately for me, more experienced guitar players are patient and answer my newbie questions without expressing annoyance. Perhaps musicians are more tolerant than Porsche People.

I don't begrudge people for asking questions that have been asked before. But this thread isn't from a new owner, it's a thread about the perception of the IMS issue. I understand why IMS is so scary for new owners. But that's why I was saying I wish IMS wasn't hyped up to be so scary. It is a known issue, but it's not a ticking time bomb, which is what a lot of people act like it is.

Perhaps sell your Porsche and buy more guitars?

The annoyance (for me) is more with the parade of responses by the same handful of bad actors that purposely play on and reinforce people's fears.

[The Radium King]

it's all about risk tolerance; a large expenditure of time/money vs protection from 2%-10% failure rate. where it is all blurred by year of car and type of original bearing, failure modes, misdiagnosis, potential failure of new bearing, multiple aftermarket solutions available that address the issue in different ways, etc.

unfortunately, the internet is not a good place for finesse; if you don't have the same level of risk tolerance as me then you are wrong. and there is some hidden (porsche?) economic hoightyness too; if you are unwilling to spend thousands to replace your bearing then you are wrong.

ultimately, i see it as a periodic maintenance item not initially identified by porsche, similar to the 15k oil change interval, water pump, tensioner paddles. further, the high-end cost of which is what, 25% of a new engine, so i, like kram, would rather save my pesos and pay the incremental cost for a bigger engine when/if the time comes. last time i had my transmission off i did not replace the bearing.

PW,
All this "annoyance" goes away by simply closing the 986 Forum which I will do next. I will then go to my shop where I must choose Porsche, guitar or lunch - retirement is a beautiful thing!
BTW, I have enjoyed your postings for many months. I just went through the headlight decision tree which was not as involved as that for the IMSB, but still fun.

It would be nice to have someone make a plane bearing like Jake's without the oil feed cheap in easy,..

They can't, the design is patented.

Plus a plain journal bearing needs a constant supply of pressure fed oil to keep the two metal surfaces separated by a thin film of oil, otherwise the bearing will fail immediately.

[Lapister]

I totally agree that the IMSB issue is overblown. If you are a Wrencher a engine is a engine whether it be a Porsche or Toyota. I read all the hype about this but couldn’t let it scare me from owning one and experiencing it. I have since sold the car after TB, 987 Airbox, and 997T upgrade but would not hesitate to buy another 986/87 if a nice one comes my way.

Jake actually tested what would happen if the oil feed failed by disconnecting and plugging the line, the answer after a prolonged period of running was “nothing”. Oil feed cools and prolongs the life of the plain bearings, but the splash oil mist seems to do a pretty good job in the short term.

Porsche would have done that if it were cheap and easy to begin with. Externally feeding oil is the only way to get oil back there since there are no oil galleys drilled in the block.

[PaulE]

Ok I was ignoring the fact that the IMS is in the sump so that makes sense. Crank journal and big end rod bearings are what I was thinking of that need the constant feed of oil under pressure. While Porsche decided to go with the grease packed sealed bearing at the flywheel engine and there is no internal oil gallery there, I don't see why they couldn't have put in a galley and a journal bearing, it is right below the crankshaft's rear main bearing. They had no problem getting an oil galley to the journal bearing on the front of the IMS. PS, I am sick of the IMSB too, having had
a preemptively installed ceramic one fail and going through a rebuild!

....has some sort of catastrophic failure mode.

Corvette 427 engines have thrown lots of rods.

BMW M5 V10 engines supposedly grenade at 60,000 miles. All of them. The internet said so.

Mazda RX-8 engines explode if you fire them up and only drive them for ten minutes. Kills the apex seals don't ya know?

E39 M5's all have bad cam phasers that need replacing.

1990 Miatas with the "short nose crank" all break their crankshafts.

Lotus Elise engines will oil starve their cams if you track them with sticky Hoosiers.

The list goes on and on.

Just add $3,000 for a professional IMS aftermarket install to the purchase price of any 1997-2004 Boxster and just spend the money on yours to get it R&R'd if you are trying to sell her.

It's just the world we live in. Complaining about it will not change the perception out there on the ground.

It IS what it IS.

Get busy livin', or get busy dyin'.

Or don't, quit worrying about what might happen and just drive.

Investing $3k in a $6k car doesn't make much sense to me, but whatever floats your boat.
