Exhaust leak or something

[luvbigfire]

I have 08 cc w cat/dpf delete and spartan. I have been driving w the 310 with no issues but last night I wot for bout 5-10 seconds and now I have what sounds like an exhaust leak. I can't find out what it is. Lost no power and truck seems to run the same. But noise is pretty loud when accelerating. Any ideas?

If you check all your exhaust components, can you see any soot anywhere?

i glanced at it last night but couldnt really see anything. I will check again right now, is there anything I should try to see in particular?

If it is an exhaust leak I would think you will see black soot in the area. Where does it sound like it is coming from?

do you have decreased boost numbers? If I had to guess its probably one of your IC boots.

Ok Maybe I am just crazy, I do not see any soot on either side of the motor. I checked the boots that I can see and am aware of and they all look fine.
Cloud- I normally have my DD unpluged so it doesnt get stolen but just put it back on so I will monitor that. The truck gauge seems normal.

I do have another issue that I noticed while I was under there. There is a white residue that has splattered down the driver side of the undercarriage. It looks like it is coming from a clamp that conects a rubber elbow to what i am guessing is the egr. Square box under the exhaust manifold driver side. Any ideas on that? She been real good to me so far and I haul very heavy but use the 210 tow and am very easy with her

As far as the leak goes you may not see soot, but if you havent done a CCV mod you may see a little oil residue on the pipes in places. I would clean everything off good and drive it for a day or so and see what new accumulations you have. Also see if you can pin point which side of the motor the noise is coming from. The white residue is probably dried coolant. That square tube is the horizontal egr cooler. If its leaking tighten the clamps, but if its coming from the cooler itself I would look into that pretty quick.

ok I will try that. Truck will be sitting next 5 days. It is really difficult to see where it is coming from, I cant get my fat head up there.. But if it is I guess i better check further. Thanks cloud for the help. If it is the cooler leaking any recommendations?

Also I prob have not done the ccv mod seeing that i have no idea what that is..

CCV is the crank case vent. You reroute your CCV so that it doesnt vent oil into your intake and fill the IC with oil. Its a good mod, and cheap. All you need is some heater hose to run out twords the back of the truck. If you want you can put a catch can of sorts on it, some have even vented into the exhaust. It is a pain to get down in there with the degas bottle on. If it is the cooler leaking and not just a fitting, I would do an EGR delete and get rid of the problem once and for all.
