Is this piston leaking oil?

[Pistoneer]

Does this piston borescope image indicates the piston rings are leaking oil?
This is an Audi Q7 2019 with 67,800 miles on it.

some of it is cut off but from what I can see I would say no. There would be a decided brown ridge on one side of the piston crown.
That said, I do see what appears to be evidence of detonation aka knocking aka pinging.

Not exactly sure what's going on on the left side? Something doesn't look right. Post a few more pics.

That said, that image is grainy and not the clearest.

Does it appear wet (oil) or dry (carbon/fuel)?

 

[Oillover]

Need more than a single picture to determine leakage.
Compression test, leak-down test etc. are where I'd start.

The spark plugs will tell the story.

 

[Pistoneer]

This is how the spark plug looked like at the time the borescope was done.

 

[Lubener]

Looks carbon fouled. Rich mix or by looking at the threads, too cold of a plug.

Is your concern is oil consumption?
Here is a youtuber who does a lot of Piston soaks on Audi automobiles with high oil consumption. Good results.

Not seeing oil contamination on that plug.....,,,,,PLENTY of carbon though. Short trips ? Got an engine light or anything ? Any modifications made to engine ?

 

[Pistoneer]

No engine light. P10A7000 fault code. No engine modifications. 24 miles a day highway + few short trips.

That could be oil deposits, The piston looks beat up in the bore scope photo (left) right on the ring land.

 

[50yr Street Mech]

Pretty beat up for 67,800 miles. 87 fuel ????? I thought those Audi's like their 93 octane. I'm open for suggestions here.

 

[Pistoneer]

92 octane only. Serviced regularly on time. Can you share what/where looks beat up in the piston picture?

About 10:00 on the photo, unless that's carbon or some other foreign substance laying on top of the corner of the piston and bore. Looks like a mouse was chewing inside there in that area. Very slight piston pitting at 7:00. Other than that, it looks good to me. Plug just looks like carbon buildup....but for 67k....should be A LOT cleaner than that. That's an Iridium plug, looks like it has 167k on it. Are you the original owner ?????

I am the original owner. My mechanic stated he sees signs of oil wash on the right side. Do you see it?

 

[50yr Street Mech]

Yeah, I see something at 2:00. I'm no expert, but I would take the advice of Oilover about 10 posts up. Sad, only 67k Best of luck. Get it fixed and run 93 octane or octane booster. .OR.........You could sell it after you fix it and try to recoup you're money.,,,or keep it and hope the rest of the cylinders don't go south on you. Not gonna be a cheap fix. Have you're mechanic look at the rest of the spark plugs. If they all look like the one in the picture, you got problems. Iridium plugs last 125k or better. The one in the pic is shot.
