Boost leak...

Do a boost leak test.

 

[red4101]

what is the easiest way to do a boost leak test

 

[Backinajiffy12]

Go with a colder Plug and check your MAS

Easiest way is to search the forums on how to build a boost leak tester, then get a air tank, pressurize your turbo and listen for a hissing sound. Just search on hear, there are 185789 different threads. You need to build one for 10 bucks. And it will then become your best friend.

Build a boost leak tester, get a spray bottle of windex ( it bubbles when air goes through it ) and start checking every pipe and fitting you can.
