Hello all
The rings came from The Seven Workshop.The ones shown appeared to be made of black cast iron.They were gapped to 6thou. The rings needed either none of very little removed to correct the gap. The gap now is around 10thou indicating some bedding in has occurred. The other areas of missed wear are also in line with the website. The compression rings have bedded better but still show signs of a slightly triangular wear pattern, 3 high points. Wished I had thought of shining a light from below. The new rings are totally different. They are silver colour and machined on all faces with the two oil control rings of different construction. The bores are all round and still show some crosshatch pattern. I would like to state this is not a supplier complaint. I am only too happy to have the level of spares that our cherished supply us all with.
