Hey my name is Ryan I am new to this site and Subaru's in general.

I have an 03 liberty B4 manual.

I had no knowledge of subaru engines previous to owning this car but due to it's ability to throw problems my way I have to learn as much as I can to fix it. My problem is a possible BOOST LEAK that I have been unable to locate for quite a while now. Now because the leak has not disappeared with what I have done I would assume it is coming from somewhere i have not touched so far so here is what I have done to her so far.

Removed intercooler and connected intake pipes from secondary and primary turbos. cleaned out as much oil as i can out of the IC and connected intake piping that come from primary and secondary turbo. replaced crappy throttle to IC pipe with new silicone tube. removed BBOD and replaced vac lines inside with new ones and cleaned solenoids. After i did this it felt like my boost had doubled and i was like fork yeah right more boost = smiles but the leak noise increased almost as much as my boost did.

Then i cleaned out the vac lines from the wastegate i think to the solenoid behind the passenger headlight in the guard lots of crap came out and now much cleaner. then did the BOV mod to attain only manifold pressure to hold it down seperating the two T pieces connecting bov and wastegate pipes. Then did the ECV solenoid bypass modification. All of this information i gained from the thread on this site named "your guide to twin turbo" After doing all this i yet again gained a bit more boost but the leak is still there and not budging.

If anyone can help me and others that have annoying boost leak issues this thread may become rather valuable and helpful to a lot of people including me.

P.S. if you want to listen to the noise search ( interesting turbo leak ? ) on youtube by 1balsybloke apologies for the name made it along time ago.

any help would be wicked cheers in advance
