Vacuum Leak

[bowez]

Getting ready to try to start my SC, now that balancer has been replaced, and did a smoke test. Well have 2 leaks 1 on by pass shaft and other on TB shaft. Are these something to worry or how do I fix them?

Have the MP 85mm TB.

It's normal for those places to leak a little. Not really an easy way to fix them.

Ok then sounds like the only real solution is disassemble rebush it and add provision for o-rings.

Not worth the effort I assume.

The idle/off idle fuel trims compensate for that minor amount of air getting through those areas. Not a problem.
