560 SEL Plenum seal job: Somebody help me out here pleeze...

[hbofinger]

So I am doing the plenum seal job on my 1989 560 SEL. I have all bolts removed that hold in intake manifold in place, including the rear accelerator linkage. The whole intake assembly budges and wiggles in the front part of the engine, but will not budge in the rear. Ruled out are:

-EGR piipe: EGR had been disconnected in the rear of the valve, should not be holding the manifold down.

-Heater hose: Too flexible, not yet removed because of bad angle.

-Any bolts: All bolts have been removed, unless there is some invisible one I am not aware of...

Anyone else run into this one?

Thanks!
