From left to right, New Gasket (part # VG70), EGR Tube to Plenum, EGR Tube to EGR Valve. EGR Gaskets. Can I replace both EGR Tube gaskets with new (part # VG70) gaskets. On the EGR Tube to Plenum gasket, why is opening smaller compared to the EGR Tube to EGR Valve gasket? Where can I buy the EGR Tube to Plenum gasket?
I bought a new EGR Valve, it cames with Orifice Washers. If the original EGR Tube to Plenum gasket is not available should I attempt to use the old gasket (this is where I think I have a vacuum leak) or use two new (part # VG70) gaskets on the EGR Tube and the new EGR Valve with the same size orifice hole as the original gasket?
If the original gasket is available, do I nee to use a orifice washer at all with the new valve?

There's a good explanation of the EGR tube gaskets and the reasons here:

Rodney Dickman offers both EGR tube gaskets on his site, so the small orifice one is available.
As for the orifice washers, you probably need the prescribed one for the engine. That orifice is likely smaller than the one on the gasket (the one on my EGR valve is) so not using it will result in too much EGR, and in any event there's no reason not to install it.
