I have just replaced the inlet manifold on my 3ltr S type 2003 after changing the spark plugs and I have found a rubber cover sat over the top of one of the old plugs, obviously come out of it's mating coil.
Do I need to replace this cover into that coil ( manifold off again)
What are my options?
Thanks
Paul
ps didn't remove the manifold completely as I was unsure how the pipe was released that's on the underside of the manifold. Is it a push fit or?? I didn't want to brake it finding out.
Thanks again

 

Are you shore it's not the rubber spark plug retainer for inside your spark plug socket ?

 

Thanks Andy, that's exactly what it is!
I noticed the last plug I installed fell out of the plug skt. and thought "that's odd" but didn't relate the two.
Any comments on my ps?
Thanks again

 

I believe you are referring to the brake booster vacuum line quick connect on the back of the intake. It operates like an pneumatic quick connect. Push in, pull out.

 

That's one concern but the brake booster hose seems to have been pushed up tight to the back of the manifold with no movement available to "push then pull" out.
the other was the pipe that fits directly under the manifold??
Thanks

 

You have to push the black ring around the booster pipe in then pull the pipe out .
Not sure about the one under it but should be strait forward to figure out .
