So my exhaust is leaking right after the turbo where the clamp is at. Just noticed this week because there was soot on my air filter. Any ideas why this would start? Would cold weather have anything to do with it? Any ideas how to fix it?

Is it where the exhaust down pipe mounts to the elbow, or is it the V clamp that holds the exhaust housing to the middle section? If your in an area that gets a lot of road salt in the winter, the salt can eat away at the metal, causes it to flake on the manafold and the turbine (exhaust) housing and some times causes a leak in the housing. I don't have any leaks in my 2001 but the housing and manafold was flaking. I did clean it up with a wire brush. Also don't be afraid to pressure wash the engine once a month threw out the winter, but make sure its hot water. It won't hurt it. hope that helps you out.

Ya but, I havent had the truck through the winter yet its still pretty new to me. But its right off the exhaust side of the turbo where it connects to the elbow between the down pipe and turbo.

if I'm understanding the area that you are referring to correctly, It could possibly be caused by stress cracks. the motor flexing but not your exhaust. Is your hanger right above your crossmember being used?

normally the stress cracks are on the exhaust manafold itself, not on the elbow. Check the gasket, makes sure all your bolts are tight, don't forget to use never sieze before puting things back together. I have never heard of a leak between the elbow and the back of the turbine housing. Do check for a crack. Look for soot marks and see where its coming from.

I dunno, we only notice the stress cracks on the exhaust manifold because that's when customers complain. After the turbo outlet not many people are really going to notice. I built a tranny for a dumba$$ with a 2000 1Ton and he was complaining about the motor and how it didn't have power. When I put fluid in I noticed a crack, just to make sure it was diffently a crack all the way threw, I started it up with the hood popped. It let off so much smoke just threw that crack I'm not for sure how he never noticed.
