Boost leak test and...
 

I was over at slowbubblecar's house and we boost leak tested my car. While testing my guage never climbed abover 0 just sat there. What could this mean?

Re: Boost leak test and...
 

That means you have a huge leak that the compressor couldn't overcome. Or your guage is broke.

It means you'll probably get banned in five days.

His guage goes to 15psi when he drives it but doesn't do anything with the tester on it. I used the air compressor and couldn't even build 1 pound. It was putting out a lot of air. I couldn't hear a leak or anything after pulling the air chuck off. Could the turbo be his leak? I had this problem a long time ago with a car I parted out and I never figured it out on that either. I was wondering how he could build 15psi when the compressor couldn't even build one.

Something is wrong with the tester.

It worked last time I used it

If this car still has a stock intercooler check the inlet and outlet of the intercooler. They get little holes in there and leak like hell.

Re: Boost leak test and...
 

It has a stock intercooler. I'll check those today. Wouldn't that make a sound though?
Also super4x4duty, It was stated in RK's bitch thread that the technical forums should be taken seriously as most the others you can kid around with; so I would appreciate only serious answers when it refers to a problem with my car. Thanks

Next time the tester is on, try removing a vac source that should be seeing pressure. That will tell you if the system is seeing any pressure. You could always bypass the turbo all together and run the test through an IC pipe, but thet might be difficult with the stock mesh hose.

I am sure the intercooler isn't the reason. I would have heard a leak there and it most likely would have needed to build boost to get there.

Re: Boost leak test and...
 

A lot of times the leak is so big that you don't hear anything. It was like that when Shane blew his end tank apart.

Re: Boost leak test and...
 

Soooo. What do i need then? New ic?

Re: Boost leak test and...
 

No look for leaks! Take a bottle of sopy water and spray it all over anywhere there is an intersection while someone else pressurizes the system. Its a pretty simple process I dont know how anyone is supposed to guide you through it any easier unless they do it for you...

Re: Boost leak test and...
 

I know what you are talking about. So on all my couplers test this? Sounds good thanks.

OK the boost leak tester isnt to test your gauge just for listening to find your leak a boost leak tester dosent build pressure in the vacuum lines just the turbo piping thats why it dosent work

Re: Boost leak test and...
 

WTF are you talking about? It will build pressure in your system and it will show on your boost gauge. Unless the leak is really big then it might show nothing at all on the gauge.

Try putting the tester on your t-body elbow. Then you can narrow down the spots at where it could be leaking from.

Re: Boost leak test and...
 

Don't say something unless you know what the hell you are talking about. Are the vacuum lines connected to the intake manifold? Yes. Does it pressurize the intake manifold? Yes. Therefore it has to put pressure to the vacuum lines also.

Anyway thanks for all the help. I'll keep trying different things. The car runs fine so I don't know whats up. I just want to know why thats wrong.

Re: Boost leak test and...
 

Ok i explained that a little wrong it depends on what line your gauge is hooked up to
if its on the fpr line or the solenoid on the fire wall which is 12v an takes power to turn it on so if you didnt have the key on that could be why or the engine might have to be started which you cant do with a boost leak tester on the car. And i belive that the vacuum ports on the TB are after the TB plate which means they wouldnt see full boost or vacuum unless the TB is open. An I dont have all the vacuum lines on my car i pulled them all except the ones i needed an i got rid of all the solenoids if ya didnt know you can do that it gets rid of the extra cludder an just something extra to go wrong.

Re: Boost leak test and...
 

WTF are you talking about I thought it was a boost issue so why would he put it on his TB? your supposed to put it on the turbo inlet putting it on the TB isnt gona do a damn thing !!!

actually it dose not fully pressurize the manifold why would you want it to thats the meaning of boost leak tester not manifold tester if you wanted to you could open the TB an then it would some an maybe you shouldnt be a smart ass if you dont know what your talking about

Re: Boost leak test and...
 

It makes no difference where you have your gauge hooked up too. When you hook the tester up and fill the system it's just like the turbo spooling so you should see the gauge move.

And start using your fucking shift key or your stay here will be short.

Re: Boost leak test and...
 

You want it to pressurize the intake manifold, because often that is the biggest problem area. And boost will have no problem getting into the intake manifold with the TB closed. If air couldn't get past the TB plate when throttle is closed, then the car wouldn't be able to idle. If you put 30 psi of pressure into your turbo inlet and you don't see any boost on your gauge, then you have a major leak or 20.

Re: Boost leak test and...
 

You are a fucking dumb ass. Could you have a leak at your t-body? Could you have a leak at your intake mainfold? Yes and yes. So putting it on the t-body will either eliminate those spots or show you have a leak at one of those spots. If there are no leaks there then it tells you that it's between the turbo and the t-body.

Alright, I can't believe you haven't been banned yet. This is a tech thread, stop giving us headaches trying to read your posts. I will say it again, shut up if you don't know what you are talking about, at least in a tech thread. In a boost leak test the air will easily pressurize the intake manifold. Your boost guage reading is coming from the intake manifold, so if that reads pressure then you have to have pressure in the manifold!
