Frequently asked questions

What is the ERR3785 manifold gasket?

The ERR3785 is the one-piece inlet and exhaust manifold gasket for the 300TDi engine. It seals both the inlet and exhaust manifolds to the cylinder head, stopping air and exhaust leaks where the manifolds meet the head.

How many ERR3785 gaskets does the job need?

The 300TDi uses one of these combined manifold gaskets per engine, since it's a single one-piece gasket covering both manifolds. You'll need one per manifold removal, and it should be renewed whenever the manifolds come off.

Where does the ERR3785 fit?

The ERR3785 sits between the cylinder head and the inlet and exhaust manifolds on the 300TDi engine. It's a one-piece design, so a single gasket seals both manifolds against the head on the Defender, Discovery 1 and Range Rover Classic.

What are the signs the manifold gasket has failed?

A failed manifold gasket usually shows as an exhaust leak with a ticking or blowing noise, or poor running from an air leak on the inlet side. It's commonly renewed when the manifolds are removed for other work, since a reused gasket can leak.

Which engine does the ERR3785 fit?

The ERR3785 fits the 2.5L 300TDi diesel in the Defender, Discovery 1 (to VIN MA081992) and Range Rover Classic 1992-1994. It's specific to the 300TDi, so confirm your engine before ordering, not the 200TDi or Td5.
