<hr size="1" style="color: rgb(0, 0, 0); background-color: rgb(0, 0, 0);"><!-- / icon and title --> <!-- message --> My new truck has about 300 miles on it and I do love it but on the first start of the day or if its been sitting a long time it sounds like a ford after a oil change. Yes, that's right engine knocks only in the morning or after sitting a long time. The only way you can hear it is if you remote start the truck while standing outside. I thought I heard something one morning but wasn't sure. I tried to listen from inside but its just to quite inside and its happens so fast I couldn't hear it all the well at first I was thinking starter noise or flywheel. So off to the dealer on Tuesday morning to see what they say, maybe there is a TSB. Maybe call them and have a flatbed bring it there so they can hear it on the first start of the day.

Mine has a little ping/tick there as well. I don't think it's a valve/lifter though. Almost like a very small exhaust leak. Maybe it's just a normal exhaust noise. I want to go to a dealer and have them remote start another identical new one side by side to compare it with.

I'm really not sure what it is at this point but I am going to make sure it's documented, it only happens on the first start of the day.

Went to dealer and ask my salesman if he had another pick up with a 5.3 in stock and he did and the first start of the day it made the same noise. Well all this means is that this truck needs a extended warranty to cover it until paid. So far I love this truck, yesterday was all highway driving was getting 21.8 MPG

I did the very same thing because I was and still am concerned with my 5.3 engine noise. Sounds like a sewing machine (click-clack kind of noise) I'm wondering if it's because of the direct injection in the cylinders that causes the noise?

Seems to me a new engine should be quiet...no?

I test drove 5 different trucks and they all made the same noise. I believe it's just a normal noise caused by the valve train and direct injection.

My 2004 with 116,000 miles on it does this when I start it (as it only gets driven once or twice a week). I had asked a "Chevy Pro" about it and his answer was, "Your engine has pushrods in it." LOL!

I would make sure that it is 'documented' and that your dealership has it I their computer somewhere -- but otherwise would not worry about it.

You could consider using the BG MOA products that give you a lifetime warranty for items serviced by the additive....
