Piston Ring Set 4mm OIL RING TD42 - Nissan Patrol Y60 GQ

Piston Ring Set 4mm OIL RING - Nissan Patrol GQ Y60 TD42 Early

This piston ring set is fitted to the pistons inside your vehicle's engine block. Piston rings are crucial for sealing the combustion chamber, allowing compression to build, regulating oil consumption, and transferring heat from the piston to the cylinder wall. This high-quality set from Engine Australia is designed specifically for the early model Nissan Patrol TD42 diesel engines which require a 4mm oil control ring.

Over thousands of kilometres, the constant friction and high temperatures inside an engine cause piston rings to wear out. Worn rings can no longer create an effective seal, leading to a loss of engine compression, increased oil consumption, and reduced performance. If you are rebuilding your TD42 engine or have noticed symptoms of ring wear, this set is an essential replacement part.

These piston rings are standard size and the oil ring measures 4mm where as the later model blacktop GQ engines and GU N/A engines run a 3mm oil ring. Please check the sizing of your pistons rings before purchasing if you are unsure.
