Piston Ring Set for the 2.25L and 2.5L 4-cylinder petrol engine, supplying the ring pack for one piston.

The rings seat in the piston ring grooves and run against the cylinder bore, sealing the combustion chamber against blow-by and controlling the oil film on the bore wall. This is the standard-size set of three rings for a single piston; one set is required per cylinder.

Frequently asked questions

What is the RTC4190 piston ring set?

The RTC4190 is a standard-size piston ring set for one piston of the 2.25L and 2.5L 4-cylinder petrol engine. It's the pack of three rings that seat in the piston grooves and run against the bore, sealing the combustion chamber against blow-by and controlling the oil film on the cylinder wall.

How many RTC4190 ring sets do I need?

One RTC4190 set covers a single piston, so a full 4-cylinder rebuild needs four sets, one per cylinder. Each set contains the three rings for one piston. Order four for a complete engine, or one if you're only working on a single cylinder.

Which engines does the RTC4190 ring set fit?

The RTC4190 standard-size ring set fits the 2.25L and 2.5L 4-cylinder petrol engines in the Land Rover Defender (1987-2006) and the Series 3 2.25 petrol. It's the standard-size pack, for bores kept at their original dimension rather than rebored oversize.

Should piston rings be renewed during a rebuild?

Piston rings are typically renewed whenever the engine is stripped for a rebuild or rebore, since worn rings cause blow-by, oil burning and lost compression. They're a standard replacement item rather than something to reuse. Fit new rings matched to the final bore size after any machining.
