Back Story: I just bought this 2003 Chevrolet Silverado 2500HD LS, crew cab, short box (with EGR). It had 135,900mi on it when I bought it 2 months ago. I now have 140,000mi. It is basically stock, with a 4in downpipe-back straight through exhaust. I am a motorcycle mechanic, and I do all my own work on vehicles, so naturally I changed the oil and filter (Rotella Triple and K/N filter), and the fuel filter with a K/N as soon as I bought it. I run 8oz of Diesel Kleen in every tank, and I have no haze at idle. Truck starts perfectly and idles smooth. I get 15mph in the city, 17 on the highway average of 70mph.
The Topics: First, on very limited occasions I have noticed (since the Straight Pipe install) light gray, almost white, smoke come from the exhaust when I revved it to 2500rpm. Today though, I noticed it a lot more. When I say a lot more, I mean there was a haze behind me, but no more than a normal Peterbuilt powering up a hill. Almost unrecognizable unless you are looking. Conditions were 70 degrees =/- 3 with humidity in the 30% range. But the Interstate was extremely hazy. It would only show the light haze at over 70mph (2250+ rpm). Seemed like if I accelerated to 80 and let off, there was more, but only until I reached 70. Then it would go away. Truck runs at 185 degrees or less (I've only seen it reach 200 when I was accelerating hard, and only on rare occasions in the past). Tranny temp is usually at 150 degrees (again, only time I see it rise above that is when I am pushing the truck hard, but I baby her most of the time).
Second thing: the entire underside of my truck, more so the passenger than the driver side, is wet. Especially after a long drive. The liquid has no taste, no smell, no color and no slipperiness/texture. It really just feels like water. When I park, the accumulator drips a lot. There is a lot of water on the frame right underneath the accumulator. Aside from that, there is the usual oil residue around the back of the motor / front of tranny, and a little tranny fluid around the tranny/Tcase. The truck is 13y/o, I expect that and it never drips. Only drip is off the AC. But yet when I park, the underside looks like I drove through a puddle. I am in NC; could the accumulator remove that much water?
Last notes: When I arrived today, I let the truck cool and set for 10 minutes, then checked all the fluids. Every level was right where it was supposed to be (Oil, Coolant, Trans Fluid, Power Steering, Brake). No diesel in the oil, coolant a perfect red color. No haze and no significant smell from the exhaust.
Any tips or insight is greatly appreciated. I am hyper-vigilant when it comes to my vehicles, so I am just trying to either make sure everything is all right, or figure out what I need to fix before there's any damage.
Thanks!
