Massive leak after skunk2 manifold installaion...

[pedroalcala]

Hey fellas whats up, havent posted on here for a while but, i recently installed my skunk2 manifold on my h22a, well i installed it got a head sheild gasket that came with it (used but still good) the gasket is real hard plastic so i know it can be reused. Anyways, im having still vacuum leak, and the RPMs are at 1800. i've checked the mani gasket with carb cleaner and nothing, even the iacv and nothing. The manifold is boreded out to a 70mm, and hence, I have a stock h22a throttle body. Could this be the cause of the leak? i think the stock h22a is 64mm, i think.

But anyways, you guys think that could be it? i did spray a little bit of carb cleaner on the top of the throttle body and it did change the tone a little. so im guessing it that. I just want to make sure if it is, let me know if any of you had this problem, as im running like crap cause of this leak!

thanks fellas!

yeah i've got a stock H22a TB on my Skunk2 IM which isn't modified and I've got no issues running a older white Hondata IM gasket. It could be leaking through those ports inside the throttle body that aren't blocked off properly since you've got such a large 70mm opening now?
