Frequently asked questions

What is the RTC419340 piston ring set used for?
The RTC419340 piston ring set seals combustion pressure against the cylinder bore and controls the oil film on the bore wall for one piston. It fits the 2.25L and 2.5L four-cylinder diesel engine used in the Land Rover Defender (up to 2016) and Series 2 and 3.
How many piston ring sets do I need for an engine rebuild?
One set covers a single piston, so you need one per cylinder. The 2.25L and 2.5L diesel is a four-cylinder engine, so a full rebuild typically requires four sets. Order by the number of bores being rebuilt.
What does the .040 inch oversize mean on these rings?
The .040 inch oversize means these rings suit a cylinder rebored 0.040 inch above standard. Measure your rebored bore first and match the ring size to it, or the rings won't seal correctly.
What are the signs worn piston rings need replacing?
Worn piston rings typically show up as blue exhaust smoke, high oil consumption and lost compression on the 2.25L or 2.5L diesel. Once the bore is worn or scored, reboring and oversize rings like these restore the seal.
