Aftermarket Part
Aftermarket: Quality alternative. This is a quality alternative, designed to fit and function like the original part, often at a more competitive price.
Piston for the 2.25L four-cylinder diesel engine, forming part of the piston and connecting rod assembly within the cylinder block.

Supplied at +0.020" oversize to suit a cylinder bore that has been rebored to the corresponding oversize, restoring the correct piston-to-bore clearance during an engine rebuild. In service the piston runs in the bore beneath the cylinder head and transmits combustion pressure to the connecting rod and crankshaft.

Frequently asked questions

What is this piston and what does the +0.020 inch oversize mean?
This is a +0.020 inch oversize piston for the 2.25L four-cylinder diesel engine. It suits a cylinder bore rebored 0.020 inch larger than standard, restoring the correct piston-to-bore clearance during a rebuild. The piston runs in the bore and transmits combustion pressure to the connecting rod and crankshaft.
How do I know if I need the +0.020 inch oversize piston?
You need this oversize only if the block has already been rebored to +0.020 inch. Measure the rebored bore or check the machine shop spec first. Fitting the wrong oversize leaves the piston too loose or too tight, so match the piston to the actual bore size.
How many pistons are needed for a rebuild?
Typically four pistons are needed for the four-cylinder 2.25L diesel, one per cylinder, so all bores are rebored to the same size together. Order a matched set at the same oversize rather than a single piston, unless you're replacing one piston in an already-graded engine.
Which vehicles use this 2.25L diesel piston?
This +0.020 inch oversize piston fits the Land Rover Series 2 and 3 and early Defender 90 and 110 with the 2.25L four-cylinder diesel engine. It's a rebuild part for a rebored block, so it applies to engines being overhauled rather than a standard swap.
