Hi

I have some question.

I end working with front cylinder and start rebuild a rear head.

I take out the rear head and start to clean the clean a top surface of piston.
When i start cleaning i feel that the piston is going a little left and right and give a little noise puk puk puk. When i try to do it up and down noting happens, up and down piston don't move. I did not feel that in front cylinder.
The compression was about 10,8 11 bar in front and rear cylinder.
I check this only wen piston was in top position and i did not check the surface of cylinder when piston going down. I remember that when i start the motor last time and give a little rpm then start a noise from rear cylinder and everything was good when the motor have work temperature.

Did you know what is to do, what i need to check or what in need to replacement

It is rather hard to tell without a complete tear down but it sounds like a wrist pin issue.

The only way to fix it would be a engine rebuild.
