I started installing my Trick Flow Track Heat intake on Thursday with some help from Launch(Brett). I finished it up on Friday, and there is a very loud whistle at idle(700 rpm), but it goes away off idle, for example if I rev the motor up or drive around. My brother-in-law and I pulled the upper off, and I put some ARP tread sealer on the screw in ports at the bottome of the intake and on the vaccum tree under the upper intake. For good measure, I put RTV sealer on both sides of the gasket between the upper and lower, I know this is not the norm, but I did not want to pull this thing off again. Anyways, the whistle is still there. My neighbor has a stethescope(sp?) and could not find the leak. I used carb cleaner and sprayed around the intake and the vaccum ports hoping for a surge in idle to find the leak but nothing. I am wondering if this is normal for this type of intake, or if anybody has any ideas. My neighbor said he thought if the lower had a leak at the heads, there would be smoke from the oil being sucked in, and he said it sounded like the noise is coming from inside the intake. I also added a 75mm throttle body/spacer, and the upper is made for a 75mm or smaller tb. Thanks.
