Vaccuum leak? What vaccuum leak? 200 1980

When I first got the "Bluesmobile" (has it really been 3 1/2 years ago?), it started great every time. Over time it has continued to start great but on trying to get it actually go somewhere it started exhibiting vaccuum leak symptoms. Alas, no leaks could be identified. Then last fall it happened - and you guessed it - a hose had come completely off (the one to the cold start injector I think). Fortunately for me Braum Schmit was in town. After George (otherwise known to me as "Dad") and I crawled around in the engine for awhile examining various hoses, Braum pointed to the underside of the fuel injection and said "shouldn't there be a hose on this one?" Sure enough it had come all the way off. Presto chango - the car went from 5 mph with the gas to the floor to a creature that yearned to run speed traps. (never got caught!) It still has its' crotchity moments but once it warmed up it was a goer. So when we got 18 inches of snow last Sunday, and it has snowed every day since, it ran a little cold the first day and got progressively worse during the week. Thursday I got to work by not letting up on the floored gas pedal at 5 mph again. A check under the hood at lunch time revealed the the hose had once again come off. I slipped it back on and it is running again. HOWEVER, I noticed when I put the hose back on that it went on a little too easy. Hmmm.... could it be the small vaccuum leak I can never find? I went over to Dad's that night and dug up a hose clamp in his garage and put it on the nefarious hose. What a difference! The Bluesmobile is running like a top again. So, to those of you who know there has got to be a vaccuum leak in there somewhere and can't find it, even with a "stethascope", don't just check to see if your hoses are on there - check to see how snug they are too!

    The one that got me was the one under the dash - the hose to the vacuum accumulator was not a snug fit, and had worked its way off. Also one of the small hoses from the ventilation control panel was off altogether. Car ran much better afterwards.

    Susan.. had a problem with the vacuum hoses getting loose also. maybe try cutting them down just a little, so they will fit back on snug enough. you could also try finding a really small hose clamp. take care.. Street

      Tie=wraps (nylon cable ties) work very well when dealing with these small diameter hoses. A lot less fussy than a hose clamp as well. And cheap to boot.

        Zip ties are the 21st century Duct Tape in my garage.

        Work great in place of hog rings for re-doing seats. I stole that from someone around here- Thanks to that contributor!
