Frequently asked questions

What is the RTC617420 piston ring kit used for?
RTC617420 is a piston ring set for engine rebuilds on the Defender 2.5L 4-cylinder turbo diesel, replacing the compression and oil control rings that seal the pistons against the cylinder bore. It's fitted whenever the engine is being rebored or rebuilt.
What does the +020 oversize mean on RTC617420?
The +020 mark means these rings are sized 0.020 inch over standard bore diameter, for engines that have been rebored to that oversize during a rebuild. Using this kit on a standard-bore engine will make the rings too large for a correct fit.
Does one RTC617420 kit cover a full engine rebuild?
Yes, one kit supplies rings for all 4 pistons on the Defender 2.5L 4-cylinder turbo diesel. You don't need to order more than one set per engine.
Which Defender engines take the RTC617420 ring set?
RTC617420 fits the Defender 1987-2006 2.5L 4-cylinder turbo diesel engine only, at +020 (0.020 inch) oversize. It won't fit the naturally aspirated 2.5L diesel or petrol variants, or standard-bore engines.
