Crank seal, VC gaskets and tube top grommets, injector o-rings and grommets, ditto on fuel rail (2x on 2 diff o-rings)and if you are doing that (along with the VSS), replace the heater hoses at the back of the block while they are easy to get to. Put it all back together with new hoses for the rest of the top of the engine. Why take off all that old stuff and put it back on. Not that much in parts $ in the end.
