Hi trying to ascertain if cylinders are nikasil or alusil in my 77 911s 2.7l.Have tried magnet test with no obvious attraction to cylinder which is stamped Mahle along with piston.The cylinder has following nbrs 9ozn2w7,147 Mahle g... plus usual grade markings,piston nbrs c021 90l61 with original style 3 piece oil cont rings.In need of one cylinder, new/2nd hnd to replace victim of pulled head stud thus want to be sure of type.The cylinders are originals 140000mls on ex calif car,first time apart!
