So i noticed there were a few people who had posts on how to figure out if you have a boost leak. Well i did the same thing, just with different parts. I bought a pvc 2" cap for my silicone turbo inlet hose and just a tire valve. Drilled a hole out of the cap and pulled the tire valve through. The tire valve is rubber and has it own groves to make a seal. Now the valve is very very tight and will hold. As soon as i get off work i will try it out and let you all know how it works. Here is a picture of my creation.
