1982 Toyota Pickup mileage: 135,000 My 2 wheel drive, 3 speed manual, recently didn't pass smog here in California for an exhaust leak and missing a vacuum hose from what looks like the EGR valve, but there are no hoses that are not hanging anywhere that aren't hooked up. So where do I start? The catalytic converter and muffler and O2 sensor have been replaced recently and are they all good? Help Please!

You can fabricate a doctor's ear and start at the exhaust manifold all the way to the end side of the C/Converter. You are probably leaking ahead of the converter and not being scrubbed/cleaned and polluting the air. You failed on this one. The EGR prevents NOx to formed-it is operated by a ported vacuum thru a TVSV/VSV/Transducer, you need to confirm this with the VECI on the hood as per its routing.
