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

![](https://www.miataturbo.net/attachments/diy-turbo-discussion-14/66245-opinions-look-my-pistons-plug_04.jpg?dateline=1359637821)
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

Well mostly because I am a bit paranoid about the car since I am driving a turbo Miata...![Giggle](https://www.miataturbo.net/images/smilies/gay.gif)
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?
