Frequently asked questions

What does the 525520 bottom end gasket set cover?

The 525520 bottom end gasket set covers the gasket and joint requirements of the lower 2.25L diesel engine, below the cylinder head. It suits both 3 and 5 main bearing engines and is typically used during a full engine overhaul on Land Rover Series 2 and 3 and early Defender 2.25 diesel models.

Are the crankshaft oil seals included in this set?

No, the crankshaft oil seals aren't included and are ordered separately. The front cover seal is ERR6490, and the rear seal is 542492 on 3-bearing engines or ERR2532 on 5-bearing engines. This set covers the lower engine joints only.

Do I also need a head gasket set for a full overhaul?

Yes, for a complete gasket overhaul you'll also need the cylinder head gasket set STC1564 alongside this bottom end set. Together they cover the full gasket requirement of the 2.25L diesel engine. On its own this set handles only the lower engine, below the head.

Which Land Rovers does this 2.25 diesel gasket set fit?

This set fits the 2.25L diesel engine in Land Rover Series 2 and 3 and early Defender models. It covers both 3 and 5 main bearing versions of the engine, so confirm your engine type before ordering, as the crankshaft seal requirements differ between the two.
