Read evidence and context
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.

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: 'Repair with dismantling' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Repair with dismantling' (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.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

Porsche Carrera S 911 997 (M97.01 - 3.8L)
The engine was under repair with dismantling.
After - have problem with work.
Сrankshaft and Сamshaft waveforms after repairing.
This is 966 model normal Сrankshaft and Сamshaft waveforms (
here
same)
Does M96 and M97 engines must have the same Camshaft and Сrankshaft waveforms?
If this correct - I think that camshafts not correctly installed !
I do not have PIWIS now.... I have Camshaft and Сrankshaft waveforms...
Do I currectly understand, what in my case I see deviation values = 15 degrees ?
Crankshaft has 60 tooths. One tooth - 6 degrees. I have about 2.5 tooths deviation .
Is this correct ?
Here
is normal deviation one tooth of Сrankshaft (I think)... 6 degrees
I have no idea, that is not the way the factory does it, and I have no idea what your "wave forms" are tell you. I do know that when one of these engines is one tooth off on cam timing, it is more like 12 degrees or so.............
Autologic, Durametric, Launch, various AUTEL, PIWIS will all give you the data you need. Also if out more than 10 degress (IIRC) a code will trip showing a deviation.
This is a source reference. Confirm exact model applicability in the original material.
