Its nothing you have to worry about right now, you aren’t leaking oil down into those spark plug tubes (based off your pictures of your spark plugs). If they were the threads on the plugs would be soaked (as oil tried to make its way down the threads) and when you removed the coils, the tubes would be filled with oil.

I’d be willing to bet your oil consumption issues are stuck oil control rings, or worn valve guides. And you can easily look inside your intake to see if there’s oil pooling in there: just open your throttle plate and flash a light in there - oil pooling could be a sign of blow by ,(worn rings/stuck rings) will cause this.

Be happy yours didn't look like this! Got new Denso's in and its running great.

In your case, you will need more just a fresh set of spark plugs.

Ya think? They looked about the same when I changed them 30-40k prior to that. What it needs is oil. Lots of oil. Every time I get gas I top up at least a quart. I have valve cover gaskets and spark plug seals but have not yet installed. She just keeps on humming and loves it when I get on the gas.

No just one point of entry via the top hat can come from the cover to tube seal or the coil to cover seal.
