    Turbo pressure loss, help appreciated.

    Hi all,

    I've been searching but haven't had success. My wife's 05 stock WRX has a leak (Pssst) noise that occurs sometimes with a subtle power loss. I'm suspect we're losing turbo pressure.

    Is anyone familiar with these symptons, any references(faqs) or recommendations are much appreciated.

    Ed

    You are going to need a boost gauge to verify. Could be a boost leak from the intercooler hoses. The problem is everybody can speculate what the problem could be in the virtual world but its up to you to verify. And for you to verify substantial data (gauge numbers) or physically checking the intercooler inlet and outlet hoses/coupling damage or looseness. The plastic hoses have been known to crack/melt.

    Thanks for the info. I was trying to understand if this might be a common/know issue. I guess from your reply that there's a number of potential causes. I'll look again for anything obvious and then likely take it the dealer.
