The Chrome compression ring used in the top ring groove of the 348 models has been discontinued and may be re-placed with a compression ring, as used in the second and third ring grooves (listed above).
The newly introduced oil control ring is the expander type known as the “Uniflex” oil control ring. The characteristics of this new ring are such that its contour follows the cylinder wall, prevents blowby and keeps the oil from passing into the combustion chamber.
These rings may be ordered from our Parts Department on the regular part order blank.
