View Full Version : vacuum leak problem

09-28-2014, 07:57 PM
so I am having some boost problems where it is like a an exhaust tick smoke test showing nothing. Of course I don't really trust that because a coupler was almost off and I caught that with carb cleaner it is still not holding but 10 hg little idle down to 18. Any ideas?

well I guess I am just going to reseal return and intake plenum and just do all new vacuum lines and zip tie and hose clamps all them.

It's pretty common for the boost/vacuum gauge hose to crack and leak. Sometimes the gauge will also get a little gunked up and read goofy...especially if you have meth injection on your car. Zip ties or clamps on all the hoses will also help.

It also got a funny tick sound like exhaust tick just not out of the exhaust. Almost like its leaking air back out of the manifold. I took off return plenum and got powder coated and intake plenum to check some things. I am thinking my problem might lay some where in there. I will check and more than likely replace gauge hose thanks David.
