Big dirty boost leak

I believe it's coming from behind the turbo but I can't tighten that stupid worm clamp any further or it skips a notch. I 'think' I checked all the other obvious spots and they aren't bubbling the soap so frig me (stuff around turbo, tb, cc, cv, solenoids, hardpipes, wga etc.)

What do I do? Is there a better clamp for behind the turbo? Spots I could be missing? I'm kind of a newb to the boost leak testing, but I know what slow feels like.

With the compressor hooked up and running it'll only get up to 2 psi on the guage :crying:

Its the stock worm clamp right? Loosen off the worm clamp, then loosen the two bolts that hold the charge pipe on (under the car). Install a t-bolt clamp and tighten.

If you slide the charge pipe slightly down you can get the new clamp onto the back of the turbo easier then actually opening the clamp and trying to close it around the pipe.

I hope this didn't confuse you more.

Good Luck

black line blocked off to the airbox?

Is that a 2.5" T-bolt clamp that I need? Stock turbo.

Ya, I plugged the black line to the intake (airbox).

Thanks.

Not to hijack but I think I still have that black line hooked up to my K & N CAI.

What is the advantage of plugging it?

For boost leak testing you have to remove the intake to hook up the tester.

You plug the black line to the intake to seal the system.

(btw, paint your rims bronze! bronze 19's on an e-blue SRT... most enviable combo IMO)

Well I installed the T-bolt clamp and fixed what I thought was an area of issue on my hotside pipe.

Still the same performance out of the car and the the system could only be test pressurized up to 2 or 3 psi, don't know what to do now. Anybody in the London area have experience with this stuff?

Thanks

dude, if you can only get 2PSI in the system then you would hear a very loud whooshing sound from a hose that is probably just about off. I'm wondering if you're just using a crappy compressor that can't pressurise the system fully for some reason. You shouldn't be hearing anything.

I think you are using an electric compressor....

no?

you're right, it's a compressor for tire inflation, thought it would suffice. I can't hear a big leak but there has to be one somewhere, the power is just not there anymore.

Thanks

electric compressor is not large enough to work. You need an actual air compressor with a tank. I would say minimum 3 gallon. That's what I've got, and it works ok.

Okay, so now I'm looking to visit someone in the London area with a real compressor. I'll bring beer, brand of choice for the host. Thanks.

This will still leak. You need to fully cap the black line while testing. Big compressor FTW...

I stick an extension in there, then I tape it off for testing, no air coming out of there.

Okay, so I'm going to get it tested at someones place SAT with a real compressor. Hopefully I can hear the leak and it's obvious.

Been reading some other threads and looking at some engine bay pics... Should I permanently cap off the black line that goes to the Intake??? (not the IAT, the other one)

Frigging hate it when she's not running up to snuff!!!

Tested with a compressor:

It seems that boost is POURING out of the body of my Kinetic Wastegate. I assume this means I need a new wastegate, can someone confirm please?

Also, what is the best WGA available?? (spring strength and durability are my priorities)
