My thoughts are the cores turned in during times like yours are stripped down and quality checked for cases and other major parts that are good.
Leading evidence: 'Check cases and other major parts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'tracking term' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check cases and other major parts' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

(For anyone interested, mine was replaced because of high oil consumption.

I went to my porsche specialist yesterday to get the coolant changed (I do it every 2 years)

Suspected cause
therefore it is most likely a tracking term so they know what engines are new and which ones are re-builds...
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
I'm still very concerned about whether the updates to the reman engines have fixed the problem.
I just had a reman 3.6 engine put into my 02 C4S by Porsche under warranty. The dealer told me that the Reman engines were basically brand new or had a minor issue which would have been repaired. The Reman engine is an 05 model based on the engine number.
Can anyone tell me what the difference is between a new engine and a Reman one? And if there is no difference, why does Porsche insist on calling them Reman?
Thanks guys
a new engine is made with all new parts (no used) and a re-man is made with some used and some new

did you have a choice?
They are called remanufactured because they are remanufactured. My thoughts are the cores turned in during times like yours are stripped down and quality checked for cases and other major parts that are good. Then Porsche takes all the still good stuff and makes it a remanufactured engine for resale with your replacement plan if it goes bad.
I'd like to see some performance upgrade options in the remanufactured engine deal but eh.
This brings up an interesting question. My car (1999 C4) has a remanufactured engine that was installed in Oct 2007. It has about 20K miles on it.
How reliable is the rebuilt engine likely to be (it is a MY2000) compared what it would have been originally (i.e. because it is remanufactured is it less likely to have RMS/IMS issues?). The reason I ask, it that I am about to replace that transmission and while in there I could do the LNE upgrade for not a lot more money.
Thoughts?
I was talking to a porsche master mechanic a few days ago about the IMS issue and asking him for help replacing my bearing. He said even the remans "with all the upgrades" are failing as well. He said it is also not just limited to the 996 but to the 997 as well. He said there seems to be sweet spots for the failure 5K 30K and 120K miles.
Let's get him man hehehe
I wanted to say that but, 'you aint getting anything free' was included.
I actually view a remanufactured engine as better than new in the aspect of machinings and other impurity items aren't as bad as new engines have.
I will say for you guys getting new or remanufactured engines and please follow along. A break in period highly involves both engine break in and getting the break in oil out in relatively a short period. Say a few months max.
Do not
figure you haven't done the break in
miles
so drag your feet till the mileage is met before dumping the oil. The oil during a break in takes a hit from the stuff it gets in it. Get that stuff/oil out and if you still haven't finished the miles break in run it up to to the miles changing oil every so often till you get there. New engines mainly concern bearing lubes and machining metals. Even remanufactured engines are going to dump their bearing lubes and some shavings from unbroken in metal parts making their mating. blah blah blah take care of that replacement engine. To be a nag even more think about silt being in the oil and settling on your bearings for the crank and such after turning off the engine. Take care.
No. As the man said, " if you come in with a Bic pen, Porsche wants you to leave with a Bic pen" albeit one that works. Also, because it was at Porsche's expense, no warranty extension on the Reman engine other than my original CPO.
Jon, I am not so sure that's how it works. What I understand it to be is this:
If teh owner pays for a reman engine, he gets a two year warranty from the date of engine install. However, if Porsche pays for the reman engine under the CPO warranty, the warranty on the engine expires with the CPO warranty, even if that is only a day, or a week, or a month after the engine install.
I could be wrong, but I have read that version on RL on more than one occasion.
I really love my car, but everytime I see a new blown engine in our spanish forum (soloporsche.com), I have more and more fear...
In soloporsche we have lots of user with "minor issues".
I'm decided to reinforce my engine.
I went to my porsche specialist yesterday to get the coolant changed (I do it every 2 years)
My mechanic advise me to upgrade the IMS, but he wants to change several parts as chain tensioners, chains, etc...
I couln't trust in any M96 reman engine till I'd upgrade my motor.
Hmm, interesting. Wonder if there are any Porsche service managers on the site to confirm?
For me hopefully a moot point since I am almost a year into the reman engine and it's been running great. At the time, the service manager told me it had a two year warranty, but she might have been mistaken.
(For anyone interested, mine was replaced because of high oil consumption. I documented it well, and upon inspection they found badly scored cylinder walls. Interesting that it still had very good compression and leak-down tests.)
You are correct. I pushed for a 2 year extended warranty on the reman. No dice. It's the Bic pen argument I mentioned earlier. If you pay for the engine you get the 2 year warranty. If they pay, no extended warranty.
I'm still very concerned about whether the updates to the reman engines have fixed the problem. I explored this with the PCA 996 tech advisor who said that he had heard of no problems with the reman M96 ( non TT or GT3 ) engines. Pipe in here any time Jake if you have any experiences to share.
I've heard of a reman grenading because of bad IMS from somebody @ porsche... but they said its very rare and I don't know what year that reman was produced ... remans from later years 2006 and beyond are probably more "updated".. the early remans would have basic stuff replace to ensure functionality but a lot of parts use to be transferred over... today's remans are out of the box and in your car...
it still doesn't do anything for the basic design problems of the m96 under high g cornering and oil starvation..
