Hey guys, I've been troubleshooting a vacuum leak for quite some time now and finally decided to make a custom pressure block off for the intake tract. I pressurized the system to about 15 psi, sprayed soapy water around the engine and found leaks at the vacuum block, at a vacuum line, and at the intake manifold (the worst being the rear of the intake manifold on the drivers side). I just replaced the intake manifold gasket but it must be garbage. I used the felpro metal valley gasket.
Has anyone else had issues with a stock manifold? I'm wondering if the manifold needs some milling because of poor stock alignment...
Any opinions? I need to get this fixed! Tired of dealing with vacuum leak issues...
