All of the fuel line, water line and oil line copper sealing washers are dealer only.
32mm heater union sealing washers are dealer only.
Cold start injector gasket and copper sealing washers are dealer only.
Get an EGR cooler gasket from the dealer. Made out of metal not cardboard.
Injector insulators = dealer only.
Turbo oil line gaskets = dealer only.
You can't get the turbo gaskets separate from cheap parts stores. But the turbo gaskets come with a head gasket set from cheapo auto. Same deal for the injector O-rings, and CPS O-ring, cam seals, EGR valve gaskets, water outlet housing gasket, and ISC gasket. You can get these parts, only in the head gasket kit though.
Everything else is fair game.
