Frequently asked questions

What is the RTC5774 decoke gasket set used for?
The RTC5774 decoke gasket set reseals the cylinder head and top-end joints on the 2.5L 200/300 TDi diesel engine. It supplies the head gasket and adjoining seals needed when the head is lifted for decarbonising (a decoke) or a top-end overhaul, then refitted to the block.
Which Land Rover does this decoke set fit?
This decoke set fits the Land Rover Defender 1987-2006 with the 2.5L four-cylinder 200/300 TDi turbo-diesel engine. Confirm your engine variant before ordering, as the naturally aspirated diesel uses a different gasket set.
Is this a top-end set or a full engine gasket set?
This is a top-end (decoke) set, covering the cylinder head and its adjoining joints only. It's fitted when the head is removed for decarbonising rather than a full engine strip. For a complete bottom-end rebuild you'd typically need the full engine overhaul gasket set instead.
Is fitting this decoke set a DIY job?
Fitting the decoke set is typically a specialist job. Removing and refitting the cylinder head on the 200/300 TDi needs correct head-bolt tightening in sequence and careful cleaning of the joint faces, so most owners have it done by a workshop unless experienced with top-end engine work.
