Magoo: Your technical post sneaked in before mine. I wasn't refering to the smog stuff. Was just kidding! |

hans, I don't know what you are referring to as "Udder" nonsense, because it sounds like we are both on the same page talking about the AIR Pump system. If you are talking about the spelling of Utter, that should be Udder, I stand corrected. |

Magoo: That's UDDER nonsense.
Mike: There are 'issues' with disconnecting and/or removing the pumps.
1. Don't confuse the smog pump ports with the mixture 'inspection' ports. The smog pump connects to the head itself. The real obvious ports on the manifold are just for sampling the mixture for adjustment purposes.
2. W/pumps installed, functioning, with belts in place: You have ridiculously high manifold temps. Also, many qualified mechanics, such as Mark Spencer in the Bay area, claim that the high temps will hurt the exhaust valves and/or guides.
3. Belts disconnected, everything else in place: Manifold temps come down. Everything seems happy in Ferrari-land, except: There are some pipes that stick into the exhaust ports where the smog pump connects to the head. These still get real hot, and may continue to contribute to guide probs, etc. But probably no worse than with the pump hooked up. What will happen, tho, is that exhaust will heat up plumbing that previously had cool air flowing thru it, such as the AIR pump manifold, and the diverter valves. Also, those tubes sticking into the exhaust ports. Without occasionally reconnecting the belts, all this stuff will go to hell in a handbasket.
4. Just get rid of it all: Probably the most healthy alternative for the car, but there are legal and/or registration probs, depending upon where you live. Also, purists won't like the deviation from stock. My car is this way. If you do this, be sure to remove what's left of those exhaust port tubes. |

Mike, There is no doubt that if the pump is disconnected for a long period of time the valves and injector tubes will burn out and the pump will probably seize. Thus allowing exhaust leaks. You can disconnect the pump but it should be run ocassionally. Even then you shorten the life of the tubes. Eventually you will have to remove the tubes and plug the holes. So whatever he chooses, but remember when the pump is not running the hot exhaust gases are taking their toll on the entire system. |

So, let me get this straight--I've got this buddy with a carbed 308 and he's trying to figure out if he should go this route. Doing this would mean removing the belt from the air pump? And what about all those things in the header/manifold--would it make sense then to plug them? My buddy, as I recall, also found these plugs, but he's worried about the effects of doing so.
Doing this would never *hurt* the car in terms of functionality, right? Some say that keeping it disconnected can cause the air pump to seize...
Do most 308 owners keep the pump going or not? |

Hans, I gotta agree. I would think that a "Utter Martini Up" is the best drink for that post. |

Think about it before you take "Him" for a drive and 'blow' "Him" out. |

What's with the "him" thing, Matt? I think I need to refer you to Bret's link for a little mental tune-up.

Matt, You're not coming out of the closet with a "he" name for your Ferrari are you? |

Hans,
I agree. "his" ngine temp dropped way down. It smells a little more then it use to. Which does not say much. It is a joy to drive. I am curious how long it will take "him" to warm up in the morning now.

My california 1975 308 car is exempted from the entire airpump system because "parts no longer available" status. |

Oh, BTW, Matt, Rob Garven claims that no belts dropped his manifold temps from near red hot to 'normal'. PO of my car measured 1800 deg w/pumps hooked up, 800 after 'parts turned up missing'. |

My stuff seems to have, err, fallen off.
BTW, reconnect once in a while, as the diverter valves and other items can get carboned up, possibly to the point that they no longer work. The pumps will blow them out.
And I always thought the best kept secret for a carb 308 is a good insurance policy and a leaky fuel hose. |

Well, at least from me.
I was told to disconnect the belt that drives the emissons pump. I was told it would run better. I then told my "friend" about it and he disconnected it. And WOW!!!. no more burbling on engine brake and SSMMMMOOOOOOOOOTTTTHHHHHH and a baby's bottom.
thoughts? |
