I installed a itr manifold into my B16 and it sounds leaked. What i used is the stock manifold gasket because it's still good, stock B16 Throttle, ANd most of the stuff from my b16 manifold is on the ITR manifold. What Happen.???

 

check your vaccum lines

 

leak makes a sound. to find out where, make a ghetto stetoscope and probe where the leak is, it should be then easy to fix except if the mani is not flat.

 

Spray some carb cleaner around your intake manifold. Where it leaks, it should also bubble. Good luck!

 

Did you torque the bolts to 18 ft.lbs starting in the middle? Use carb cleaner. When the leak is located the idle will change.
