Frequently asked questions

What is the +0.040" piston ring set used for?

This piston ring set seals the combustion chamber and controls oil on the bore of the 2.25-litre 4-cylinder petrol engine, and also suits the 2.5-litre petrol which shares the same bore. It covers a single piston on Land Rover Series 3 and Defender.

What does the +0.040" oversize mean?

The +0.040" (1.0mm) oversize means the rings are ground 0.040 inch over standard for a cylinder rebored to that size. It's typically the largest common oversize, so it's usually used where the bores have already been machined out furthest. Don't fit it on standard bores.

How many sets do I need, and are there alternative part numbers?

You'll typically need four sets, one per piston, for the 4-cylinder petrol engine. RTC241040 and RTC277440 are listed as alternative references for this +0.040" set, so either may appear on equivalent ring sets for the same oversize.

What are the symptoms of worn piston rings?

Worn rings usually cause blue exhaust smoke, high oil use and low compression on the 2.25 and 2.5-litre petrol engines. Rings like these go in during a rebore, and this set matches a block machined to +0.040" oversize.
