mbb, you never covered the functionality of your centrifugal and vacuum advance. These two can create emissions issues as well.

Since my air pump was producing what I think is close to the minimum out put (2.1 psi at 1200 RPM), I sent it to B-Z Rebuilders. And a few days later, I did get it back. It looks great and feels good when I turn it over by hand and it is installed back in my truck.
Thanks for the picture Spike. Those SSTs are really cool. The one with actual pressure measurements does confirm what I found in a Toyota technical document that “good” starts at 2 PSI. When you measure a pump about where on the scale does it read? My pumps are reading just a little more than 2 at 1200 RPM. Thanks.
BZ recently charged me $280 including return shipping. The turn around time for the rebuild is one day. They do need you to send a rebuildable core.how much was the rebuild at B-Z Rebuilders for the Air pump? My new 60 is still smogged and I may keep it that way..

Well I'm pretty sure the vacuum advance is working. At least applying vacuum to either diaphragm will rotate the distributor plate. And the truck drives fine, no pinging or stuttering under load. I don't have a timing light with an advance mechanism to be more quantitative.mbb, you never covered the functionality of your centrifugal and vacuum advance.

not yet. I'm only put on about half that. I will drive it some more then go back and retest the air pump output. Thanks.Have you put 500+ miles on the rebuilt air pump? That is the break in for internal parts for optimum output.
I agree that the probe length issue is BS. They have been selling this Cat for some years and it doesn’t make sense that I’m the first one to have a problem. The ceramic matrix is only about half the length of the cylindrical section so there is some flexibility where it is installed. I asked them to share their fabrication drawing with me but they declined.Personally, I think the Magnafuk BS about probe length is BS. I have a bunch (mostly non functional), and they're all the same, though the part number does change at the 5/85 change-over date. I have noticed that some have a longer CABLE, but that's it. The late 40 series and 55 have this probe with different part #s also though I've never seen any.
I think MF just F'd up and don't care. My earlier Magnaflow direct-fit CARB CAT with the same part # as current one, the sensor fits fine.
The O2 numbers are also affected by the gas you're using - Generally summer blends are heavily oxygenated, Winter blends, much less (at least here in the AQMD). And this all may be moot eventually as Newsom and Co continue to drive refiners out of Kalif.
Glad you passed.
