I am putting the pistons in tonight due to lack of time because of work. The directions from Langs were lost: which way does the taper face for the rings? Does the taper of the top ring face up and the mid ring face down or vice versa? Much thanks in advance.
Tapers always go up.
You want the widest surface to be sealing on the bottom land......
so the bevel/taper on the mid ring will also face up then: (the flat, undisturbed part faces down?)
Bottom ring is 3 piece with thin top and bottom and corrugated middle, next ring is tapered with a dot on the top of the ring, top ring goes either way. This is for hasting rings.
Both set of rings I have installed had a mark to indicate which side was the top.
