Boost Leak - How, Where, Why, possibilities?
I am struggling with my 156 2.4 JTD.
Since owning it, for about 6 weeks, it has made a loud hissing noise over 3000rpm, I assume this is a boost leak, so I have checked the hoses, have replaced the intercooler with a brand new one, (Wow what a fun job that is!) and still the noise persists.
Can anyone with more knowledge than me tell me what else I need to replace to stop this leak, where else can it be coming from, is there an ECU issue that is making it dump boost somewhere. PLEASE HELP ME PLEASE!!!!!!!!!!! I want to love my car, and the wife doesn't want me to buy a GTA!!!!
