Boost leak

When checking for boost leak should you be able to hear air leaking or should there be no sound?

I'm using about 5psi and I can hear a leak from the turbo area, I soap up the intercooler and spider boots and no leak.

What could be the leak at the turbo?

Any ideas ?

Thanks

Re: Boost leak

Did you forget to check the IAH or the bolt if you removed it?

Did you check the actual detector seal and its fittings?


You should not hear air passing if there is not a leak.

IAH bolt? What is that?

Yes checked the detector and its fittings no leak.

If that is a leak would my boost be low?

My egt's rise very quickly especially when I get on the throttle hard,Ican hit1300 easily.

I will try to check it when engine is cold so I can get to the back of turbo.

Re: Boost leak

It is the intake air heater. It is a unnecessary part that actually takes up a considerable amount of space in the intake.



Read this: Air Intake Heater Plug

You can replace it with a 5.9 Cummins oil pan drain bolt.


If you are still running the CCV into the intake tube did you remember to pull it off and block the hole? Otherwise you are trying to pressurize the whole engine.

Re: Boost leak

If you already have a boost gauge you can check that as well to compare the two gauges or use it alone.

Okay sorry I know what you are talking about I just saw IAH ( AIH )No leak there.

No I did not plug the hole I wil try it again.

I did find a leak at the rod on the bottom of the turbo,should there be air at the rod?

Re: Boost leak

Okay Tarm pluged the ccv and now no leak, thanks for the tip.

Why would there be air at the rod at the bottom of turbo, was it going through the ccv hole?

Would the air eventually leak down if there is no leak?

I'm using about 5psi and if I leave it for a few minutes pressure will drop but no sound of air leak,and no leak with soap water.

So no boost leak what could be causing my high egts?

What is the danger zone and how long can you hold it there?

Someone mentioned you would have to hold it for a long time before distruction is that correct?

Re: Boost leak

Sorry that is my dyslexia kick'n in when its late.

That's the rod from the EBPV coming thru. Would think it should not leak but someone on here cloud tell you for sure. I have not used the leak tester on my current ride and may last truck had did not have the ebpv so... But I can tell you if you have the crank case vent still plugged into it and you have the leak detector plugged into the end of the intake tube no the turbo that is most likely the sound you hear and what is dropping your pressure. Sure would take much more air volume if nothing else.

Try that and I think you should be good.

Back to your issues. Is the main one hot egts for the most part? What about smoking? Boost level?

Did this just happen one day or has it been this way since you installed the chip and gauges?

Have you checked you up pipe at both ends?

Thanks plugged the ccvand all is good no leak.

I think it happen when I did the chip and gauges.

Up pipes for leaks? No leaks

Could it be the tuner,maybe I should give Jody a call.

Egt's seems good at cruising speed, it just when I get on the hammer . Also when I did some data logging I didn't even look at my gauges,just was concentrating on the raod . I'm sure it got up there in egt's.

Any more ideas?

Re: Boost leak

Don't forget your valves. You are going to have an open intake valve or more, air will leak past those.
