Frequently asked questions

What is this Piston used for?

This Piston is for the 3.5L Rover V8 petrol engine, supplied at +0.020in oversize with an 8.13:1 compression ratio. The oversize suits a block that's been rebored 0.020in, and the 8.13:1 ratio matches the low-compression V8. It fits the Series 2/3, Defender, Discovery 1 and Range Rover Classic.

How many pistons are needed for a rebuild?

The Rover V8 has eight cylinders, so a full rebuild typically needs eight matched pistons. Buy them as a set so weights and sizing are consistent across the engine, rather than mixing a single replacement with the originals.

How do I know this is the right piston for my engine?

Match both the oversize and the compression ratio to your engine. This piston is +0.020in oversize, so it only suits a block already rebored to that size, and its 8.13:1 ratio is the low-compression version, not a high-compression one. Confirm your rebore size and compression ratio before ordering.

Is there an alternative part number for this piston?

This piston also cross-references to RTC218620. If you find that number in a catalogue or on the old part, it's the same +0.020in oversize 8.13:1 piston for the 3.5L Rover V8.
