Cayman S 2006 IMS fix??

2006 Cayman S - IMS fix?
Soooo tempted to grab this car.... am getting snagged on the IMS Issue. Anyone know a reasonably ($) good permanent fix for 2006's IMS?? Is bearing concern an overhyped and non-real source of worry??

2006 Porsche Cayman S

The 2006-2008 IMS bearings still fail, just not in as large numbers as the single row.

LN Engineering makes a retrofit kit for the 06-08 engines which will allow you to use either their ceramic hybrid or the bullet proof IMS Solution. Unfortunately, you need to take the engine out and apart to do this update.

I was doing the same looking around last year and ended up with a 2007 Cayman S, 54K miles $21K. Had service records. $22K is an OK price, but not a steal. If the IMS stuff keeps you awake at night, go for the 2009 or newer. I'd bet if you take the $22K for this car and add $2K for IMS fix you can get the 2009+ model. By the way, I ended up putting a clutch in after driving it after 6K miles. So be aware, 50K miles is getting into new clutch territory even if it seems good now.
Seems like most agree these need to be driven and they need regular oil changes.

Isn't it possible on a '06 third gen IMS

to remove the seal from the bearing to improve oiling. Is't that what Hartack in the UK does? Takes trans removal.

Yes Mike, you are correct. If you are not going to retrofit the 06-08 engine, pulling the rear seal is the next best bet; no supplemental oil feed is necessary or even helpful.

How many retrofits have been done?

Last time I talked to Charles the number of rebuilt IMS shafts was less than a dozen. Granted that was probably several years ago but speaks to how few were being done compared to the earlier IMS versions.

Mike, LN now makes an bushing/insert that can be field installed in the third design shaft, with an inner diameter that will accept the field serviceable LN IMS retrofits, including the IMS Solution. So it converts the 06-08 cars to the earlier design:



If you look closely, you can see the bearing is inside an insert. This still requires disassembling the engine for the installation of the bushing, but after that it is field serviceable.

And Merry Christmas, by-the-by...............

While on the topic, whats the price of a dealer/factory teardown and of a competent private job? I'm on the east coast for what it matters.

Define "teardown". At the high end, replacing any part with known problems with redesigned/improved parts or just crack the case and insert a new upgraded bearing?

Teardown as I see it means removing engine unit from vehicle totally, then making repair or adjustments. I had an old VW once that required an engine replacement, private mechanic charged $600 odd for labor and replacement engine was around $400 - $500. When repair was complete sun roof stopped working along with heater.

So you want the labor hours for an R&R, remove and replace. Engine and Trans. put on stand and remove transmission from motor. Not including any repairs. Not including any work to separate case to access IMS. Not including any parts. What year? Model? What transmission?

If you gave me this in person I would not give you my car to repair. None the less I persist as my time to own a used Porsche is nearing. Dont worry I plan to buy a Durametric so we can knock off for the scans.

I have investigated this. The short answer is it expensive! A new motor is about $18k plus install. A full rebuild of an existing motor is about $18k. The LN upgrade to a 3.6 or 3.8 from the 3.4 with some goodies on top of that AND with the new IMS bearing is more. Opening up the engine and not doing pistons, cylinders, rods, rings, valves etc and the IMS, plus a new clutch and flywheel might be a teardown but not exactly a proper rebuild.

if you like the car, and the price
buy it
drive it
rev it.
and give it frequent oil changes.

it's an M97 engine, so not servicable anyway...

Great, thanks! I knew it was expensive, just read the other areas of the forum. So I think how can a pre 2005 Cx 911 with hi milage go for under $22000? Whats the sense or logic? I'd much rather a 996 than a cayman. Whats the life expectancy on an ancient 996? This is evolving into a topic for another area of the forum, sorry.

I too have been surprised at the prices of the M96 996 cars. The only thing I can come up with to explain it is the same thing that has affected 986 prices, people read about them and are scared and so they are tough to sell, not appreciating, etc. Add in that some are now 20 years old and lots more work on them needs to be done, parts and labor hours are expensive and you have big $$$ to maintain a reliable car. 100k miles scares lots of people and Boxsters and even Caymans accumulated lots of daily driver miles.

A while back, in my community there were several of us who had 986 era cars, now not so but a few 993s. Since it is a community populated by people in the prime years of "boys with toys", I think this expresses the collective opinion about the value of these now old cars.

I can replace the IMSB in the car, if that is the real problem. If it's a spun rod bearing or cylinder scoring, it requires teardown. I am in NC near Charlotte. I can save you thousands $$$
Not Mike Focke approved repair but I have put 52,000 miles on an engine with this process.
I have posted DETAILS and PICS for your perusal. Just google SAPIENTONI

Defining "rebuild"

My first Porsche rebuild was for a friend of his 2.2 in a 914-6 original. There is a book with Porsche engine specs which sets upper wear limits or an acceptable "range" of part fitments. New piston rings had an end gap in his cylinders that was at the very upper limit. I don't recall what gap the rings that came out of it had. This engine got bearings, rings, those danged studs, and seals replaced, but the pistons and cylinders were worn to the very upper limit. He was too cheap to pay the $1200 they wanted so the engine went back together as he wanted it. Of course it didn't run very smoothly. It did seem to run well, but we had no other example to compare it to. I was not experience with Porsche air cooled then. He was directing what he thought it needed or what he wanted to spend money on. We tried balancing the Webers and improved the running a little. However when I suggested a compression check, the results were 90,120, 100,130, 110,90 psi. I think the numbers were supposed to be about 150. So you can see why the engine wasn't smooth and for certain wasn't putting out the 155 hp it was rated at. He was just using it as a daily driver and cruising, so it wasn't tooo bad, just a super poor monetary decision in my opinion.
