so i had/have some leaks causing my idle to not go below 1300rpms. first i tried spraying carb cleaner around and i could tell there was leaks but i couldnt see where they came from.
so then i made a simple plug to fit on the end of my throttle body elbow or turbo inlet with a tire valve on the end of it, this enabled me to pressurize the whole intake, this worked better and i found 2 leaks in the upper manifold this way, but i couldnt see where the leak below the manifold was.
so i made a 10" aluminum plate that can be bolted to either the UIM or the lower intake manifold. I put 4 tire valves in for each runner so i can test each section seperately. it works so much better, now i can actually look and feel around as i pressurize the manifold. Plus i can plug both ends of the UIM so i can test the unit outside of the car on a bench. heres some pics.
