    2000 DeVille Dirty Air Tube

    I have a 2000 DeVille and my dirty air tube for my pcv valve is broken where it meets the intake manifold. What can I use to fix this problem with out getting a new one? It is creating an vaccum leak and getting annoying. Please help this my first cadillac.

    Cut out the damaged section and replace it with some 3/8" fuel line hose.

    Don't think that will work (if the OP is talking about the elbow - part #570). You can probably find an elbow at the Help rack at most parts stores. Otherwise, get one from most any GM dealer parts dept. Even there, it can't be more than a few bucks.

    on my 04, which is a little different, the rubber coupling on the other end split, i replaced it with a piece of fuel line hose. I had to replace the elbow (570) several years ago, the mechanic said he was able to get at it with long needle nose pliers.

    The elbow cracked on my 2003 and caused a p0174 code. I put, or more like stuffed a surgical glove around it until a time when I can make the proper repair. When the car is running, the vacuum pulls in the glove to seal the leak. Had it on there for two months now and the code is gone. Helped me pass my emissions inspection.
