What else should be replaced while the intake is off
 

My 2001 4.4 is getting a new intake gasket installed. While in there I am having them change the valley pan gasket, oil separator, waterpump, and upper and lower radiator hoses. Is there anything else that should be replace while the top of the engine is appart?

Thanks

The gaskets for the rear coolant crosspipe. (the part the metal tubes that come from your waterpump go into on the back of the engine) It is one of the only parts on a BMW that uses a "regular" gasket. I usually pull the rear cross pipe vs the waterpump to get to the valley pan as the waterpump has often been changed by the point in time of the valley pan repair.

The gaskets are #2 in this link.
