04 996tt piston ring gap question

[t-tom]

Does anyone know what to set the piston ring gaps at on a 04 966tt. The pistons have the ring stop pin/dowel on the second ring land

Since those are water cooled cylinders I'd say use the usual standards for gap. I.E. 4.5-5.5
per inch of bore for top rings. Most important for second ring is that the gap is larger to prevent
pressure buildup between the first and second rings.
