Looking at the piston there appears to be 4 machined grooves in the outer diameter between the top ring land and the piston top surface. Also looks like a deep groove in the area between the top ring land and second ring land.
Is this correct or is it machining marks or optical illusion?
Please provide more details on the piston and what this is.
Also, are these supplied with standard OEM Goetze rings or what optional rings are included?
