5.3 engine tick - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SC C-10 · 02-20-2012, 04:43 PM

I need a little help here please. My DD is a 2001 Sierra 5.3. Never any issues other than regular maintenance issues. Mobil 1 oil since new, and a new set of 41-110 Delco plugs. The problem is I have a tick in the number three cylinder between 1100-1600 rpm. It doesn't do this at any other time through the rpm range. The truck runs fine otherwise and is still getting the same mileage as always. No codes are showing up, and this happens with the a/c on or off. It has 123,000 on the odometer, and I've had it since it was new. Any ideas or suggestions would be greatly appreciated!
Thanks.
