I have a d16y8 and i just installed a Skunk2 pro series intake manifold with a hondata intake manifold gasket. Everything installed properly. Started and it leaks vacuum from where the manifold meets the head, you can hear a suction sound. Has anyone ran this combo before on a y8 or a SOHC VTEC for that matter, with any problems please get back to me asap. Thanks guys.

 

yes i have installed one on a y8, on mine there was a hole on the drivers side of it for a sensor that wasnt on the stock y8 manifold. Did cover this hole? or have one? Try to spray brake cleaner around where you think the leak is from, and if your idle changes than you have a leak.
