Well, I called the California Bearua of Automotive Repair today, and spoke to them about finding an EGR Valve (Dual Diaphragm/Vacuum) for me (Because they have a "Hard To Find Emission's Parts Locator"), the guy I spoke to said first off, "It's not a dual vacuum is it?" and I said "Yep, that's it." and he said "Good luck man, those don't even EHXIST anymore!". So, I'm getting what's called a "Limited Parts Exemption". But I told them, that without that EGR Valve functioning properly, the truck's not gonna pass the sniffer test, and the guy said "Then once the smog referee see's that the EGR Valve isn't working, he'll just pass you without testing it at all."
I guess California Smog Junk has loopholes in it afterall! Yipee!! Only thing bad, is it takes 3-5 days for them to VERIFY that the part really IS unavailable, then it'll take another 2 days for them to mail me the sticker...at least it's GOING to get smogged soon.
