Frequently asked questions

What is the RTC4734S piston assembly?
The RTC4734S piston assembly suits the 2.5 litre four cylinder petrol engine in the Land Rover Defender, covering the piston, connecting rod and bearings. The piston transfers combustion pressure through the gudgeon pin and connecting rod down to the crankshaft.
Which Defender engine does this piston assembly fit?
This piston assembly fits the 2.5 litre four cylinder petrol engine in the Land Rover Defender from 1987 to 2006. It doesn't suit the 2.5 diesel, 2.5 turbo diesel, 200Tdi or 300Tdi engines, which use different pistons. Confirm your engine is the 2.5 petrol before ordering.
Where does this part sit in the engine?
The piston assembly sits in the cylinder bore of the 2.5 litre petrol block, connected to the crankshaft by the connecting rod. Reaching it means the engine is stripped down to the block, so this is a rebuild part rather than a roadside repair.
Why would a 2.5 petrol piston assembly need replacing?
Pistons are typically replaced during a full engine rebuild after bore wear, overheating damage, or a broken ring scoring the bore. On the 2.5 four cylinder petrol, piston and bore wear usually shows as high oil consumption, blue smoke and reduced compression.
Is fitting a piston assembly a home job?
Fitting pistons is typically specialist work. The engine has to come out and be stripped to the block, bores measured, and ring gaps and bearing clearances checked against the workshop manual before assembly. Most owners use an engine builder rather than attempting it at home.
