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.

Suspected cause
I'd be curious to see if the issue is scoring, but the Cayman forum will likely steer you in the right direction.
Leading evidence: 'scoring' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'scoring' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace after pulling the ignition coils' (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.

Suggestion
Seems simple enough to replace after pulling the ignition coils.
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.

When changing my spark plugs and ignition coils in my 2007 Cayman S I noticed oil was in every plug. The car was misfiring so I changed out the plugs and coils but now I still smell burning oil. Could this be the O-rings or something else?
Not being very familiar with your
2007 Cayman S
in the 996 Porsche forum, however, I'll venture a wild *** guess - residual oil in your cylinders being burned off. Is it consuming oil? If so, then yes, your O-rings are bad. Look up piston O-rings. Let us know what you find. Also, how does it smell warm? Just wondering....
I saw what you did there. Do you think these guys might also be able to help:

There is oil in the spark plugs, so I think it's the o ring seals on the spark plug tube that is allowing oil to leak into the spark plugs. I guess I was hoping someone would tell me I don't have to take the sparks and ignition coils off again because I just replaced everything but the spark plug tubes and the upper and lower o ring seals but looks like I'll have to. I guess I should have done a little research first. .

Not showing any O-rings on the coils, so that must be it. Also not showing spark plug tubes like on a 996 engine. Seems simple enough to replace after pulling the ignition coils.
It does have spark plug tubes with a upper and lower o ring seal, pretty much the same as the 996. If you don't have a lift it's not a really fun or easy job. Thank for the part number, have a great fourth!
Definitely see the Cayman thread. The engines aren't quite the same as the m96. I'd be curious to see if the issue is scoring, but the Cayman forum will likely steer you in the right direction.
This is a source reference. Confirm exact model applicability in the original material.
