Yeah I need to give that a try. I have that gasket, I just haven't replaced it yet because I'm still trying to figure out how to remove the intake with that giant AC in the way. I use the OGTS gaskets with usually grease on them occasionally I'll use high tack gasket sealer, but I like grease better.take carb off and try again, if noise goes away it is somewhere in the carb, either carb gasket, or throttle bushings are leaking.
get out the 15mm box end wrench and try to torque down the intake bolts a little bit.
yes I mean where intake bolts up to engine. are you using this gaskets or rtv silicone for gaskets? I do not have much experience with using a heatshield but be careful with how good the seal is.
Also there is the T coming off intake where brake booster hose hooks up, there should also be another small tube for hooking up to the valve cover. there might also be another fitting on opposite side of intake for vacuum retard on distributor. look for any of these to be not hooked up.
these fittings are dependent on year. might all be on the T or 2 and 1. In your video at like the 7 second mark, you show the gap between carb and valve cover. the black hose you see should be going to the orifice fitting on the T, in the same frame, you can see a cutout in the heat shield, this is usually for the other vacuum line. this will be where other fitting sometimes is on the intake.
All my vacuum lines seem to be connected and working properly, I tested my brake booster and it passed the the test where you put your foot on the brake then turn the key.
