Well, the car is facked again... I don't know why I put up with this thing...
Anyhow, I was driving the car pretty hard to work this morning, and as soon as I pulled off the highway I noticed that the car wasn't performing up to snuff. I parked it and heard an excessive 'exhaust/rumbling' noise coming from the engine bay, and knew right away that something wasn't right. I didn't have time to poke around so I just left it. When I turned it on again after work the noise seemed to have gotten worse/more obvious, but I decided to drive it anyway to see what it would perform like. It's almost like there is an exhaust leak somewhere, but then the turbo was making boost and I could hear it spooling (which it wasn't doing the last time I had an exhaust leak) just the car wasn't really moving. Then again I wasn't really pushing it because I didn't know what the problem was. Also, I just put the turbo back on 2 weeks ago and torqued everything to spec, so I was thinking it's unlikely it would be a leak anywhere from the exhaust manifold/turbo. I've only been running the car at 15 psi on my 16G, so not enough to be blowing stuff up I don't think. So then when I got home I tried to listen to the engine, and it seemed like the noise was coming somewhere from the intake manifold. I didn't check for intake leaks or anything, because the engine was boiling hot. Anyone know what this could be? Or where I could start to save me some time? Also, the car burned a lot of fuel... and I wasn't even boosting; almost a quater tank of gas for 25km of highway driving at 3000. However, according to the a/f gauge it was cycling just fine. This is the first problem I've had of this sort, so I'm not sure where to look and point the finger at first.
