Zafira CDTi Inlet manifold

Zafira CDTi Inlet manifold

This picture shows the broken swirl flap from a Vauxhall Zafira,the swirl flap is located on top of the manifold near the glow plugs.On removal of the manifold we found the swirl flaps completely seized.This vehicle experienced a lack of power and engine management light.Unfortunately when the Egr valve is stuck open it can allow these fumes to start coating the swirl flaps inside the inlet manifold and the first many people know about it is,either the engine managment light(EML) comes on or while doing routine maintenance they see the external swirl flap bar that connects these flaps together has fallen off.(its on top of the engine under the injection pipes)

 

Egr valve gums up with exhaust fumes and needs to be periodically removed and cleaned.
