Piston ring orientation

Forums

Hi all - I am in need of advice regarding ring orientation. I am installing new Gandini ring sets as supplied by Andover on original AE Hepolite pistons . 

The second compression ring - the central one located between the top compression ring and the oil control ring - has a rabbet around the outside edge on one face . Should this rabbet face up towards head or down towards crankcase ? I am thinking down to act as scraper but I am uncertain.

Thanks in advance for any input .

Cheers - Richard

Should have looked closer - ring was marked “top” - indeed rabbet faces down . IIRC “ rabbet “ is “ rebate “ on the other side of the pond.

Once again divided by a common language!
