Re: Inlet Manifold/ Air leak problem?!
The "plastic" (actually a fairly complex composite!) manifolds can develop problems, particularly if at any time in the past there has been a cambelt failure and the engine has backfired...
Changing the maniold is a fiddly job but not particularly difficult, especially if you can get the car over a pit or on a ramp - its held onto the engine by two (15mm?) bolts into a steady bracket, and two 13mm bolts into the ally manifold casting (these all need to be accessed from below, really), as well as the clips on the rubber piping between the plastic and ally parts of the manifold (if you dont have the proper pliers to remove and replace these - about £15 from Halfords - get four suitable jubilee clips in before you start!). There are plenty of wires and pipe connections to/on it too!
