Hmm interensting...

It also seems that I am leaking on some of the lines going to the intake mani. Stock lines use those metal type clamps, many people use zip ties because they work better? What if the zip ties on the end of the boost hose dosent work either? Try going tighter im guessing.

 

Double up the zip ties.

 

after reading this i found a massive boost leak on mine, i even took a pic....

 

What is that big thing behind the grill, thats huge leak right there...

 

attn *****!!!! lol
Im jealous

BTw, I use zip ties on vac lines. If that isnt holding, use a smaller diameter vac line.

 

Ok, but is there anthing else that I could do like high temp RTV, like just a tiny tiny bit not to impead the flow of air?

 

honestly why bother? If it fits that loose and a zip tie or clamp wont help, why not just run a diff line?
easiest and best route IMO.
I wouldnt mess with a sealant like that on a vac line. Next thing you know the line will be clogged and more problems.

 

If you are worried about vaccuum lines popping off or leaking, a drop of super glue will ensure that they won't come off without cutting them, and they won't leak boost.

Old jedi DSM tricks.

Oh and your throttle plate SHOULD be open during boost leak tests.

 

Thanks for the advice, I will try again with the zip tie again, if I fail. Super glue it is!

 

Have you seen boost leaking from injector seals or IM gaskets?
I guess I never really thought of that because its not common, but makes sense.

+1 on the dab of superglue. I never tried it, but i never had a problem with vac line leaks to be honest

 

AWD_Terror,

We see boost leaks all the time. You are absolutely correct in saying that we should have a boost leak test from time to time. On your piping you can used the ol' hair spray trick. Makes it easier to put on, but afterward it's tacky enough to help hold the tubing

 

do you do the boost leak test before the turbo or after the turbo???

 

i had a small boost leak from a coupler on the dyno, went from 400 to 450whp after we fixed it.

 

I just leak tested mine two days ago. Good thing I did. I thought the car was running okay, but... Two injector seals were leaking big time! It wouldn't hold 10 psi even though it would reach 22 psi under driving conditions. I had set the pressure regulator on my air compressor to 40 psi so I wouldn't damage anything, and there wasn't a high flow rate. I guess the turbo puts out enough flow to overcome the leaks. Just goes to show that doing a leak test should be as routine as an oil change.

 

WOW. now I gotta check my injector seals. lol.
damnit!

Also the hairspray trick is a good idea. Wouldnt have worked for me though. I gotta take a pic so you guys can see how rediculously it was rigged.
Imagine putting a 2" D ring into a 2" coupler and look thru the coupler. You will get the idea of what I was working with, just on a little bit (not much) smaller level. lol
