Can your smog pump go bad?
Just wondering as put everything back on. My smog pump does not turn smoothly. Is that normal being a pump and all?
|
Yeah, they do freeze up, especially if bypassed. The one on the engine that I bought was frozen solid.

Get rid of the smog pump.

Here in Georgia, it just has to have converters and pass the sniffer test and gas cap test. Luckily, mine is old enough to be emissions exempt.

Jim - No smog pump on mine and passed Ontario emissions- which are less stringent for an engine changed car. Have an extra Speed density computer if you need it as I changed to mass air this year. Runs and idles better. Vic

Im going to get rid of the smog pump. What all can I remove with it? Also where do I get vacuum from for the brake booster? |
All vacuum comes from the upper manifold. Make sure to keep the little check valve in the existing Miata rubber line. |

There should be a bunch of nipples to attach vacuum hoses to. FPR, brake booster, evap and other emissions use vacuum. The Mustang may have had a vacuum tee mounted on the firewall, but you don’t necessarily need it as the plenum should have an abundance of nipples. I had to cap some of mine off as there were more than I needed even without the tee. My brake vacuum hose is attached directly to the upper plenum where the tee normally attaches. Here’s a good pic towards the bottom of the page. https://foxbodyproject.wordpress.com...r-intake-swap/ |
Thank you. I will be getting into that next week. Getting close to trying to start it. |
