Finding a boost leak.

[tshirt2k]

Just checking pipes won't find you leaks.

I don't have any and I dont have a smoke tester 

How can you tell? I don't have a smoke tester either! You will never know unless you pressurise your system upto your max boost. Just checking hoses won't tell you if you have a tiny leak that passes a lot of air once under pressure.

it will because you would have oil all over where the split is.

I have replaced EVERY pipe on mine that carries boost and there are no leaks.

My boost pipes werent full of oil....think your turbo seals are dying mate.

No oil in my pipes either. So your saying you can't be sure you dont have leaks because you haven't pressure tested the system up to 20 odd psi. 

Even when you think its tightened up. They can still leak, especially with jubilee type clips.
