Exhaust Manifold Stud for the 3.5L V8 petrol engine, securing the exhaust manifold to the cylinder head.

The stud screws into the head and carries a nut that clamps the manifold flange against the port face. Threaded 5/16" with a 1.5" length. Manifold studs are subject to repeated heat cycling and frequently seize or break on removal; renewal on reassembly is good practice.

Frequently asked questions

What is the Exhaust Manifold Stud for the V8 used for?

The Exhaust Manifold Stud secures the exhaust manifold to the cylinder head on the 3.5L V8 petrol engine. It screws into the head and carries a nut that clamps the manifold flange against the port face. It fits Defender, Discovery 1 and Range Rover Classic with the 3.5 V8.

Why do V8 exhaust manifold studs fail?

V8 exhaust manifold studs sit in constant heat cycling, so they frequently corrode, seize or snap during removal. Renewing the studs on reassembly is good practice once the manifold is off, as a seized stud that breaks in the cylinder head turns a simple manifold job into a drilling and extraction repair.

How many studs are needed for the manifold?

Each 3.5L V8 exhaust manifold is held by several studs, so you typically replace them as a set rather than singly. Because they often seize, fitting all new studs while the manifold is removed avoids a return job. Count the stud positions on your Defender, Discovery 1 or Range Rover Classic before ordering.

Which nut fits this manifold stud?

The matching fixing is the hex nut, part number NH605041L, a 5/16 inch UNF nut that clamps the manifold flange onto the stud. The stud itself is threaded 5/16 inch with a 1.5 inch length, suiting the 3.5L V8 exhaust manifold on Defender, Discovery 1 and Range Rover Classic.
