Okay, I have a previous post asking if it sounded like i have a boost leak and many of your guys' response was yes. You guys said to do a boost leak test. So i found this, Visual Frequently Answered Questions - Home Page, but i am not sure where i hook this up to. The building of the tester seems pretty easy, just not sure how to use it.

Thanks in advance

Sorry just realized that link is taking you to the home. The tester can be found in the intake tap and then all the way down it'll say intake leak tester.

Lol it's in that article in vfaq you just linked. To use it, just remove the intake pipe from your turbocharger inlet and attach this in its place.

I didn't see any info in your profile, so I think you are stock besides the front Intercooler.

If you don't have an aftermarket boost gauge, then you need to hook up one so you can see how many psi you are putting into, other wise, you will end up blowing something.

Install the BLT and a gauge to measure psi, then spray soapy water all around the pipes, couplers, throttle body gaskets vacuum hoses, intake gasket and injector seals, after you do that, then start pressurizing the system and pay attention to see if there are any bubbles coming from the couples gaskets etc etc etc.
If you are stock, then don't go over 15 psi, adding only 10 or 12psi will be plenty for your set up.

You don't need a boost gauge to do this. It's helpful to see how long it will hold the pressure, but necessary for the test. I've tested both my cars to over 40 psi and never had a problem. (You should always test at least 5 psi over whatever the boost is set at)

I am totally agree with you, But How did you know you put 40psi?, with the stock gauge?, You definitely need a gauge, not only to measure the psi your are putting in, but to see how fast it loose pressure, However, Can't you seen the OP?.
He doesn't know anything about BLT, so is always to guide him on the save way, with out any knowledge about what he is doing, he can put 60 or even 80psi and damage something.

We all ready have knowledge on this, but we all had our hard time when learning and damaging things with out even knowing.

Lets help out the OP going on the save way.

I have a gauge on my tester. Its super easy to build a tester with a gauge for those vehicles that dont a boost gauge. Additionally, with your "standard" 20 gallon compressor that most people have in their garage at 90 psi you should be able to add air until it starts leaking out the valve cover breather and then spray the couplers and gasketed areas with soapy water to find the leaks. It shouldn't take much more than that. It takes quite a while with a large compressor to even get near 60psi, especially on a car with a large frontmount. Most people with smaller compressors will have a hard time getting to 30 because the compressor just can't supply that much cfm.

Can i just use the gauge on my bike pump?

You're going to want to use a compressor. There is a very large volume between your piping, intercooler, and intake manifold to fill with air. You'll be pumping your arm off to fill this volume as it's bleeding off. This isn't like filling a bike tire.

Nice, that's all what I want to hear, and that's what we need to tell the OP.

To the OP.
If you are talking about the bike pump, Then no, Like Jon91TSI stated, you will never be able to build pressure in the system, But If you are talking about the gauge it self, then yes as far as you find the way to hook it up to the Boost Leak Tester or via a hose going to the Intake Manifold or any source of the Intake System, it will work, The only purpose of the gauge is to read psi, so any gauge can be hooked up.

Okay so I made a tester and got it on the intake side of my turbo. When I put air into the tester and spray soapy water, the first place I noticed a leak was the flange on the elbow that is hooked up to the turbo and has a intercooler pipe attatched. I also notice a little leak on my flange where my stock bov is connected. It's very little though. The intercooler elbow flange that is hooked up to the turbo is much larger then the bov leak. The elbows leak is big enough to hiss. I also think that I might hear some noise coming from around the intercooler. Do any of these leaks matter much.

Thanks

You should try to go for NO leaks at ALL.. As it affects performance and also causes idle problem with stock MAS. Replace any gasket that is leaky, I use a very thin coat of HT silicone on my gaskets.. helps somewhat. Also try replacing any cheap screw-on clamps for T Clamps or something better. It usually leaks around gaskets, couplers, and clamps. If those coupler pops off, you will have a dead DSM. :notgood:

I'm really not sure, I haven't ever owned a stock DSM LOL. Measure it?

As for the leak at the J pipe. Buy a new gasket for it, and coat each side with a thin film of high temperature RTV(orange/red colored), tighten it down good and let it dry. Replace the gasket for the BOV and do the same there.

Once you fix those 2 leaks, You will probably find more.

Boost leaks make the car run rich. Which kills fuel economy, power, and the car all together doesn't run as good.

Yeah, my gas mileage is like probably around 15 mpg city. I can almost watch it go down. And i was planning on buying the vrsf fmic kit which would require me to get a new elbow, so i will proly just wait untill i buy the fmic. And on running rich, sometimes i can smell gassy fumes when i start the car. And on power, when i step into the gas, my car does a strange rev, and the turbo gauge goes all the way up and bounces, and my car goes nowhere. I have a forum about that problem and i dont know what it is. Somebody told me its seems like a boost leak because of the bouncing boost gauge, but i dont know. I need to get it looked at by a professional.
