you should just borrow one of my boost leak testers. you find the leaks by listening for hissing and then poor soapy water over all of the areas where you think there may be a leak. If the water bubbles, that is where your leak is. To seal the leaks, either tighten your hose clamps if thats where the leaks are, or use some rtv sealant to close up pinhole leaks around the BOV or TB. most likely, your leak is between the outlet of your 16g and the j-pipe.
