At idle I have 15hg of vacuum and the gauge flickers slightly. I am thinking the plug and the vacuum nipple I put on the intake might be the culprit , or one of. What is the best thing to use as a sealant for them , the tape or the sealant in the tube. I have used the sealant , but it seems to run up the threads when I tighten it down . Thanks for your replies Dave |

Dave Ive had problems with both types...that being said what works for me is putting the dope type on a let it sit overnight then put it in. Seems to set up some then stay put better. Frank |

No sealant should be necessary; that's a tapered (pipe) thread that self-seals when you thread it in securely. If the plug or fitting you're using doesn't grow tight as you thread it in, it's not the correct thread and it'll leak. |

That vacuum reading is low. Stock cam? Did the gauge flutter before? |

Yes, that is a low reading and should be 18 or 19". Hook it up to the carb not the number 6 intake runner. When was the last time you set your valves? or does your motor have an after market cam with allot of overlap? |

Ted , I have never set my valves, my motor has like 72,000 miles. Dan, I am using some sealant because the vacuum tree that was in it was broke, and it took some messing with to get it out. It is just a just in case thing to eliminate it as a cause, but it does tighten Frank , I was thinking about letting it sit overnight , so thanks for the info. Rug Trucker ,everything is stock. it now read at 650 rpm it read 16hg, and at around 1000rpm it reads 19hg. I will have to do some more investigating when I get a chance. Thanks for all of your replies Dave |

On the valve adjustment , I guess if I have hydraulic lifters there is no need to adjust valves , is this right ? Dave |

Unless your motor was swapped you should have solid lifters. 18-19 is a good idle vacuum. |
