Considering picking up 2000 Boxster S. Seller says that MY is not prone to IMS failure. True?
Not completely true. MY2000 could have either a dual row or single row IMS. If it's the latter, it's way more likely to fail, however both can indeed fail.
+1 with Charles.
I have a 2000 S (new to me) which will receive the LN bearing this spring. Just negotiate that into the price.
Do not believe the line that it hasn’t failed yet so it won’t. A replacement engine is at least twice the value of the car’s current value.
My IMS bearing was failing at 95k miles and was the dual row style.
My base 2000 Boxster sat for 10 years and I bought at auction. Pulled trans and found a single mass flywheel with a dual mass clutch. Made the tools to pull the IMS bearing and found a failing bearing. There was a lot of "silver" in the IMS tube. I made a centering sleeve that mounted to the IMS bearing flange on the block and a driver for the bearing so it was installed square with the tube. I cleaned everything up, ordered an OEM style bearing from 123bearings.com in France ($75 delivered) and put it back together with the stock flange using a viton o-ring. I also changed out the spark plug tubes as a couple were full of oil and the AOS Dropped the sump and cleaned with no real debris on it. Made an aluminum plug to replace the oil filter bypass in the filter canister. Drove around the block and all was normal. Finishing some body work on the bumper covers and will be back on the road.
It has been stated that the IMS tube may be slightly bent on some engines. This could accelerate the time to failure which no one has mentioned. Possibly a major cause of failure?
My trusted independent Porsche shop told me many years ago, the whole IMS thing is somewhat an "overblown conversation" on many owner forums. In their 55 years of Porsche service they had only seen 1 example of a failed IMS. They went on to say that in my case (1998 Boxster base 5-speed w/92,000 miles) IF I haven't had any issues in the first 92,000 miles I won't have any issue in the future. Their advice was to just change the oil & filter every 5,000 to 6,000 miles, and since it's just a sunny day summer driver only, that translates to ONE oil change a year in my 26 year old pristine Boxster.

Now bore scoring, that's a non issue for that model.

I believe the guy who has videos taking us through the rebuild process.
I believe the guy that says it affects 10% (oops said 90% wont be affected - forgive my brash math calculation)
I have a hard time believing something the guy's indie shop said many years ago when the first guy has videos of recently received motors waiting to be repaired (assumes he really has a backload of motors to rebuild).
I had an 07 Cayman S. the prior owner spent 26 grand to rebuild the motor properly. Didn't have an IMS blowout. They caught it right before it blew. So that probably doesn't count?

Google PCA and bore scoring for more fun videos.
Oh, I have nothing nice to say about the people I've dealt with at PCA in their ivory tower. However, the videos are not the people, and are excellent.
I guess the only thing that's agreed is that ALL BEARINGS WILL FAIL. If so, then I guess I've had 25 years and 92,000 miles of "good luck". I'll take my chances that my IMS continues to be fine with my yearly oil/filter changes. My beautiful 98' base 5-speed Boxster is my 4,000 mile per summer, top down fun ride . So....my attitude is DRIVE ON as I always have, top down, on warm summer days!

The IMS lawsuit and settlement in which Porsche was forced to admit to the percentage of failures was many years ago. The cars with an IMS are many years and many miles from that point and certainly can be expected to have seem many more failures since then. So using the numbers from years ago doesn't represent the frequency per car that should be used IMHO.
These cars are really old folks. And many have gone through many hands and who knows how well each of those owners has maintained their cars. How many have maintained to perfection? It wasn't thought to be a future collectable after all.
No car is without its problem areas. The IMS just happens to be one of those areas.
And that 2000 year just happens to be the one which doesn't help identify which engine with which IMS bearing was ready when it was built. And the car could even have a replacement engine with any of the three bearing types or the bearing could have been replaced with any of a dozen replacement bearings.

Is 2000 Boxster S prone to IMS failure?
