Both my neighbor and I are re-building short frame unstyled B's. We were putting new rings on his, and the three compression rings had a dot on the ring indicating placement toward the head. The fourth ring on the skirt (oil ring), did not have a marking, however it has a small chamfer on one edge, and sharp 90 on the other. The one we took off had the chamfer toward the head, and the rings on my B's pistons were just the opposite. Obvioulsy one is wrong. Which way does the oil ring go...with the chamfer toward the head, or toward the crank?

Jon - Not so short: Although oil rings come in a large variety of designs, they must all do the two same things: (1) distribute enough oil to the cylinder wall to prevent metal-to- metal contact, and (2) control the amount of oil distributed. Without an adequate oil film between the rings and the cylinder, undue friction occurs, resulting in excessive wear of the rings and the cylinder wall. On the other hand, too much oil is as undesirable as not enough oil. If too much oil is distributed by the rings, the oil may reach the combustion space and burn, wasting oil and causing smoky exhaust and excessive carbon deposits in the cylinder. Such carbon deposits may cause the rings to stick in their grooves. Sticking rings lead to a poor gas seal. Oil rings provide proper control and distribution of the lubricating oil. The bevel on the upper edge of the oil ring face causes the ring to ride over the oil film as the piston moves toward top dead center, but as the piston moves downward for intake and power, the sharp lower edge of the ring scrapes or wipes the oil from the cylinder wall. The oil ring is, in many ways, the most critical ring. It must give maximum oil control while metering just the proper amount of oil to prevent excessive wear or scuffing.

In short: The scraper edges of all oil control rings must face downward (toward the bottom of the piston) for proper oil control

I had to ask the same question on this board two years ago. Same thing BMAN said. Chamfer toward the head.
