Frequently asked questions

What is the ERR3331 cylinder block seal used for?
The ERR3331 cylinder block seal is a 16mm sealing washer that closes off a machined passage in the Rover V8 cylinder block casting. It seals an internal drilling in the block, forming part of the cylinder block assembly on the 3.9, 4.0 and 4.6 V8 EFI petrol engines.
Which Land Rover models does this block seal fit?
This block seal fits the Rover V8 EFI petrol engine in the Defender, Discovery 1, Discovery 2 and Range Rover P38. It's specific to the V8 cylinder block, so confirm your engine is the 3.9, 4.0 or 4.6 V8 before ordering.
When should the cylinder block seal be replaced?
Replace the cylinder block seal whenever the passage it seals is disturbed, typically during an engine rebuild or when chasing a coolant or oil weep from the block. These seals can harden and leak with age and heat cycling, so they're usually renewed while the engine is apart.
