Exhaust gasket blown on #4cyl = black carbon-boost leak?

[xxconvict]

Ok, so i noticed there was some black soot on my heat sheild and on my turbo and surrounding areas from the number 4 cylinder. My best guess is that its a blown gasket. So my next question is, if it is a blown gasket will there be a loss of boost? I'm pretty sure there is and if not i have a boost leak somewhere cuz i wasnt boosting much today, it kinda felt like fuel cut......later

Yes you will loose power depending on how big the leak is. When you first start your car can you hear a ticking noise? I would replace the gasket and check for boost leaks.

Not when i first start it up but now that I think about it, lastnight when i was out driving i heard a tick. It kinda sounded like a rattle from inside the car toward the front of the dash(closest to the motor) but i couldnt find it maybe thats what it was. OR are u refering to the pcv valve?

If it was really leaking that bad you would probably hear a tick if you start the engine when its cold before the manifold expands. Either way it is a good idea to replace the gasket. If you still notice a lack in power check for boost leaks.
