P194 of the GCR states:
Piston rings are unrestricted provided that:
1. One oil control and two compression rings are used
2. No modification is made to the piston for the installation of rings.
Is the top ring in a gapless set considered 2 seperate rings, or a single 2 piece ring? (the standard oil control ring is called 1 ring but it's 3 pieces)
Thanks in advance.
