Default Opinions on the look of my pistons

Hi guys,

I recently bought a simple USB stethoskop camera to have a look at the top of my pistons...

This is how they do look like:

(from front to back) - and the spark plugs for the cylinders
Cylinder Nr. 1



Cylinder Nr. 2



Cylinder Nr. 3



Cylinder Nr. 4



And here are the videos of the cylinders
Nr. 1

Nr. 2

Nr. 3

Nr. 4

Looks like I got a wee bit of knock, some carbon buildup...

What are your opinions/suggestions?
Thanks

I cant see the pics (unsure why they didnt attach here). Otherwise, I just watched vidceo 4 and I dont get to see the squish area.

It looks like something ventured into/bounced around your #1 cylinder maybe. Unless that's just indents into the carbon layer?

Looks like the carbon layer is crackin and flaking.

The real question is, what made you look into this? Do you suspect something is wrong?

The carbon layer on the pistons look to be breaking off. I am with Miater on this did you have a problem you are trying to solve or were you just looking to look.

Well mostly because I am a bit paranoid about the car since I am driving a turbo Miata...

Also since the car is off the streets during winter time - I have to keep myself busy.

So you think it's just carbon layer flaking offf?

I would say its just carbon flaking off. If you run water/methanol injection they will be almost brand new clean with in two days.

Fuel injector cleaner will do a pretty good job of the same thing. Let it get sucked into a vaccum line a little at a time.
