They are recommended IF you overbore the block and use over size 76.75mm pistons. Will you?
Measure your bore in three places. Measure the piston for each bore. Should be 76mm for an A14. Piston to wall clearance should be between 0.001" and 0.018" give or take. If much over that it should be over bored and over size pistons used. Using a 0.75mm over size ring to make up the difference is not advised. Certainly NOT without some measuring. When compressed the ends may touch or touch when heated up and they will break.
No mention of honing the cylinder walls. If the stock pistons and walls are withing spec the wall will be too smooth to wear the rings in. If using case iron for this you need a special hone.
If going to larger pistons and over boring the finish will be perfectly round and no taper. For this you can use chrome molly rings for much better seal and longer life.
I'm going to be using the stock pistons & everything is within spec. Should I still give the cylinders some fresh cross-hatching? Also what kind of rings would be the best in my case for best performance & longest life? Thanks everyone!
