This beautiful 1964 Morgan 4/4 has been in with us at Bridge Classic Cars for a couple of issues.

Most notably is the rough running from the 1600cc engine. After inspection, our in-house technician Ady discovered there was an issue with the manifold that was causing the exhaust to blow and therefore the engine to run poorly.

With this information, we managed to source a replacement manifold for the car and fit it. However, the replacement manifold didn’t quite line up with the threaded hole on the cylinder head. So, carefully Ady elongated the holes to allow it to bolt up while also keeping the gaskets perfectly in place to achieve the correct seal.

After this had been done and the manifold connected back up to the exhaust system. Our in-house team went through the entire system from engine to exhaust box to check everything was working exactly as it should on the Morgan.
