Frequently asked questions

What is the diesel piston ring set used for?

The piston ring set seals one piston in the 2.25L and 2.5L naturally aspirated diesel engine. The rings seat in the piston grooves and run against the cylinder bore, sealing the combustion chamber against blow-by and controlling the oil film on the bore wall.

How many piston ring sets do I need for a rebuild?

This set covers one piston, so you'll typically need four sets for the four-cylinder 2.25L or 2.5L diesel engine. Each cylinder gets its own ring pack, so match the quantity to the number of pistons being rebuilt.

What does the +20 oversize mean?

The +20 marking means the rings are machined 0.020 inch oversize, sized for a cylinder that's been rebored to its first oversize. Standard rings won't seal a rebored bore, so confirm your machining size before ordering.

Which engines does this ring set fit?

It fits the 2.5L naturally aspirated diesel in the Defender 1986-2006 and the 2.25L diesel in the Series 2 and 3. Both use this 0.020 inch oversize ring pack once the block has been rebored.

What are the signs worn piston rings need replacing?

Worn piston rings typically show as blue exhaust smoke, high oil consumption and lost compression from blow-by past the pistons. Rings are usually renewed as a set during an engine rebuild or rebore, not in isolation.
