Piston Ring Set for the 2.5 litre four-cylinder naturally aspirated diesel engine, standard bore size. The rings seal the combustion chamber against the cylinder bore, carry heat f rom the piston crown out into the bore wall, and meter the oil film left behind on the liner. Worn rings show up as falling compression, rising oil consumption and crankcase blow-by, and are renewed whenever pistons are disturbed or the block is honed. Supplied as the ring set for one piston - four sets are required for a complete engine. Rings must match the finished bore size. Show more
