Exhaust Leak?

I was looking for a fuel leak while my truck was running and noticed that i have exhaust flow coming out of my engine near the turbo. i tracked it down and it looks like it is coming from the turbo pedistal. when looking at the pedistal when its installed there is a rod that goes into the passengers side below the circular exhaust deal thats hooked up to the turbo. i have noticed exhaust the cabin for a while now and never really thought about it. has anyone ever had this problem and what exactly is it that its leaking out of?? thanks

Are you noticing any power loss? have you noticed the the smell since you changed the down pipe? could be the down pipe not on properly or it could be the gasket between the exhaust up pipes and the turbo. the thing you are describing is the exhaust back pressure valve control cylinder and that would be leaking oil if anything

Cant really say if i have a power loss. The truck has had so many issues I dont know what its supposed to be like. i physically saw puffs of exhaust somke coming from out of that hole with the rod and it does look like it has or does currently leak a little oil out of that hole. I have checked the DP and the fitting if flush and clamped but I am thinking about getting some copper seal and trying that on th DP as extra security...

It sounds like the ebpv valve is bad. Especially if yoiu see oil leaking out of it. You can remove it and gut it but there will need to be some welding done to plug some of the holes. tjbeggs has one that is done like that.

What kind of benefit/loss is there to gutting it? I mean its not going to hurt anything right?

Correct but it does impare the flow thru the intake but not much. Those who have it gutted never plan on using it (obviously) and they are fine tuning as much as possible for performance. I would like to do that soon but no hurry.

I'll bet you a dollar that your up pipes are leaking. You would see exactly what you are describing. And it's a very common failure on our trucks. Not to mention, I have the same problem on my new truck. Hope that helps.

No, I mean the pipes that feed the turbo from the back. One pipe comes off each exhaust manifold and turn directly up to the turbo. Where they both meet the turbo, they are sealed with a doughnut gasket and flange. They are very prone to leaking. Powerstroke shop dot com sells them for right at $200. You get new pipes and all. But I don't have the link.

Hi Bob I don,t have a pic but if you are looking at the turbo just behind it there is a square piece with four bolts this is where the up pipes bolt to rite behind the exhaust side of the turbo if you can,t see it jump up on the bumper and look rite in there behind the turbo

hope that makes sense lol
