I have had an exhaust leak where my downpipe connects to the motor for about 1200 miles and was about to get it fixed. I started it up and the leak sounded alot worse and my boost gauge is only showing 11 vac. It was showing 18-19vac. I drove it around the block and the turbo is still boosting but the engine sputters and does not have much power. my questions is ................Did I blow my motor? or is the exhaust leak gotten so bad that it is running this way? Please help

Could be just your lower intake manifold gasket. "Just"is saying it lightly... it's a b1tch to replace. The original ones are paper and are notorious for blowing out.

Does your car smoke while running?

had similiar prob, when putting on downpipe,
it smoked in the turbo region
i just carefully used a little silicone gasket maker from AutoZone and leak is gone
