Exhaust leak ?
 
It burns my eyes....

My car is running very rich. I have the RB 3" turbo back exhaust. When I put the BOV on it it ran more rich. It seems to have some sort of gas or exhaust leak. I believe there are new gaskets, at least the gasket connecting the turbo to the downpipe. The smell is strongest in the cabin and under the car, but not under the hood. Im not sure what to do. Please help, any input or ideas. The smell is very strong and it burns my eyes. Thanks.

Yeah, that "Help, I'm being maced!" feeling goes away after being around it for a while... :)) (probably due to carbon monoxide poisioning)

Since it's an exhaust leak, why not just take the system apart (from the exhaust manifold back) and use some copper silicone to seal everything back up. Be careful no to use too much on the wastegate of the turbo, or it might create a restriction. Also, get some new gaskets if the old ones are bad and try to get the actual metallic gaskets (they last longer). It's most likely leaking at the turbo flange; sometimes it just doesn't like to seal (distortion). Worst-case scenario, the exhaust scroll of the turbo might be cracked. If you've got the stock cats, check to see if they're plugged-up (missing substrate/abundance of carbon). Very simple problem, just take some time and take it one thing at a time.
