I'm several days late, but this past Saturday, I finally had a stainless steel exhaust system welded on. I'm running a Flowmaster Super 44 series muffler, 3 and 1/2 inch tips with a nice sized downpipe. The shop did a great job and it only took them an hour. I'm very happy with the sound. Its not too loud when casually driving, but it sounds great and is loud when you get on it.

Everyone should get into the habit of checking their oil level at least once a week.

Those look really good with your paint color.

I've read that the oil pump is making the noise. Its supposed to be normal, but just a loud pump.

Hell, with these trucks, make sure to hit at least 80 on the highway to make sure it doesn't have Chevy shake!

Disconnect the negative battery terminal for a few minutes and then put it back on. See if that fixes it. These trucks have quite a few electrical gremlins.

Another option that you could try if nothing else works is taking it to another GM dealer and see if they would take care of everything under the CPO warranty. Its worth a shot asking and if it works out, great.

If anybody is looking for a great website to purchase auto detailing stuff to help with this issue or for any other detailing needs, autogeek.net has everything you'll need. They also have sales and discounts going on quite a bit.

That really sucks. I hope you can get your truck back quickly.

I totally misread your second post. I thought it said that they wouldn't turn on. When they won't shut off, does it happen when the truck is off or only when its on?

Have you checked the fuses for the lights and camera?

That would make sense then and I know when the door opens that the fuel pump is priming itself. Thanks for your help.

Yeah, the gasket was designed to be reusable. Same thing with the transmission pan gasket.

I tried listening for the noise inside the engine bay and had someone else turn the truck off, but I couldn't hear it then. Its only noticeable from inside the cabin. Could it be the HVAC system releasing pressure? When I turn the truck off, the HVAC unit is always turned off.

I'm trying to figure out this noise, but I can't really describe it. I'm not sure if its normal or not. The noise only occurs when I turn the truck off. It last for 2 to 3 seconds and its coming from the driver side of the engine bay. If I had to guess, it would be a vacuum leak noise, but its not a whistling noise. The truck isn't throwing any codes and is running perfectly fine. Does anyone have any idea of what it could be? I also tried searching for it on the forum, but I couldn't find anything on it.
