Frequently asked questions

What is the STC298220 +0.020 oversize piston for?
The STC298220 is an oversize piston assembly for the 300Tdi 2.5 litre turbo diesel engine, machined 0.020 inch (about 0.51mm) above standard bore size. It's used when the cylinder bores have been rebored oversize during engine reconditioning, restoring correct piston-to-bore clearance.
How do I know if I need the +0.020 oversize piston?
You need the +0.020 oversize piston only if your 300Tdi cylinder bores have been machined 0.020 inch oversize. Confirm the actual bore measurement with your machine shop before ordering, since fitting the wrong oversize piston gives incorrect clearance and can damage the engine.
How many pistons are needed to rebuild a 300Tdi engine?
A full 300Tdi rebuild needs four pistons, one per cylinder, as this is a 4-cylinder engine. The STC298220 is supplied as a single piston assembly, so order four matched pistons of the same oversize for a complete engine rebuild.
Which Land Rovers use the 300Tdi oversize piston?
The STC298220 oversize piston fits 300Tdi-engined Land Rovers, including the Defender, Discovery 1, and Range Rover Classic. It only suits engines fitted with the 300Tdi 2.5 litre turbo diesel, so confirm your engine type before ordering rather than relying on model alone.
