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.

oh on a side note it seems like the air is coming from my primary injector area, what would be leaking there? When the engine was running it didnt seem like it was leaking any fuel... hmm?

turns out my primary injectors dont have any diffusers or seals anywhere under them so i odered them from ray.

That is awesome! thanks for sharing. I like the leak tamer but your way is affordable.
