Sorted the inlet manifold. All seated nicely now new gaskets the inlet elbow and EGR valve. But now I have a new noise on my 1996 Preg 2.5Td Limited Cherry Pre facelift.
Once the engine is turned off I can hear a buzzing from under the bonnet. Open the bonnet and hey presto, My Electric Vacuum modulator (sat behind the air filter housing) is buzzing/whining... If i pull one of the hoses off, there is a sudden gush of air and then it all stops. The engine appears to run fine but only happens once I turn the engine off. Or am I showing my complete lack of knowledge here and its a common thing?
Any ideas as to where to look first?
Thanks all in advance for you help ......
