Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.
Discussions that report identifying a cause

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'bore scoring' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'bore scoring' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace ims' (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.

ANY used car I buy gets a oil change A.S.A.P If it's a Porsche I also remove the oil pan to see what's in there if anything, & send a oil sample to LN engineering The IMSB experts.

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.

I just purchased this car and the IMS has not been done. I have read everything and now I am seeing blurry.
At 65000 miles , from 0-10, o being none and 10 being it will explode, How would you rate my chances of having an IMS failure at this point.
Only reason I hesitate not just pulling the trigger and doing it is that for this early 997.1 I understand it requires and engine drop.
Thanks
John
It has the larger non-serviceable IMS
The motor case would have to be split to replace the IMS
They have a 1% failure rate from what I’ve read
Bigger issue is bore scoring
Negative. Some 2005 models may have had the replaceable bearing, but not the ‘06.
Drive the car. Change the oil every 3-4K and at least annually if less. Don’t worry. Be happy.
Pull the oil seal on the IMS. I did at ~57k. I now have ~112k miles.

This is my normal ride, this is a highly modified 2.7 twin plug, screamer. I am new to water cooled
Anyone know where I can get 997 Factory workshop manuals?
I found all the manuals and Tech Bulletins. I think my insurance will be drop the engine and do a full service. At minimum I think I will do RMS, Serpentine belt, filters, plugs, and IMS. If case has to be split, I will service what I can without that drama, unless I find cylinder scoring.
Another fun project!
Further research indicated that IMS Failure in 2006 models were slim to none on builds after 3/2005 - Mine was built 08/2006. I am not going to worry about it.
