Macster,
I concur with your prior post, BUT all too often I talk to owners who believe that just because they have kept their Porsche serviced that the IMS failure will not happen to them. (similar to what the OP in this thread stated)
Only a couple of times last year did I talk to owners of failed engines who said their Porsche had not been well maintained prior to it's failure.
The bearing beginning to fail is generally what compromises the bearing's seal- Thats when oil starts entering the bearing and the hollow shaft, then you end up with the IMS leak of death, but not all failures have this or the same symptoms.

Looks like this. This is what we found when we opened it up to install the bearing upgrade. There had been no leakage visible from outside.

Thats a very early one, but that nasty black oil starting to drip from the 4 O clock bolt is a classic. If the oil that leaks onto the floor under the car is darker than whats on the dipstick thats when the trouble really begins.

signs & symptoms
Jake,
I and many appreciate the rich discussion. Can we assume that if the engine-transmission junction has ANY sign of an oil drip (moisture, wetness, drips) that we are running a risk? Can we also assume that if the same junction is bone dry that we should continue to monitor as we do the rest of the car and get back to basics (driving the car)? Do you routinely see failed engines with absolutely NO visible signs at the junction? I am guessing probably not. Probably no owner wants to admit he never looked under his car for signs of potential engine failures once the bearing fails. My take on this informative thread is kick the tires, look under your engine and run your engine judiciously.

Interesting.
Not bragging mind you, but just noting for the record this must mean my 02 Boxster with 227K miles still has an original and intact IMS bearing seal?
If so, what could have possibly kept the seal intact all these years, and miles? Could it just be the luck of the draw?
I will also point out that my car has received 5K mile oil/filter services from day one. (Actually, I treated it to an early oil/filter service at 2K miles, then another 3K miles later, at 5K miles, then 5K miles thereafter.)
Not leading up to anything in particular, just asking, no more like thinking out loud.
Sincerely,
Macster.

If the engine is making any sounds, do NOT fire it up. I haven't read any of your posts that state any of the IMSF symptoms thus far.
When a bearing has began to fail, makes noise or has IMS drip syndrome (very nasty black oil discharge from the bellhouse area) the engine's life can be measured in seconds or minutes. Once the bearing gets bad enough to alter cam timing by 16 degrees the valves will contact the pistons and the engine looks like 3 mile island inside all at once. I have one of the worst IMSF engines we have seen thus far ready to come apart this week, wait till you see these pics!
Shark, I answered as many of your questions as I can here on Rennlist.

Do you have to take the engine out of the car to do the work?

Depends, They make a retro fit kit that can be done in the car, then they make an entire upgrade kit that requires the engine to come out of the car and the IMS to be machined to take the new bearing. So pick your flavor!

Poured what seemed like a quart of oil out of the shaft when they removed it.

Yes, the retrofit can be done in-car for any M96 powered Porsche up to 2006.
In the Washington area I recommend SCAN Automotive, they are one of our partners there and have done the IMSR successfully.
