Hi Guys

I'm new to this sight and thought I would try to get some help here. I have an 06 Colorado
3.5 I-5 11000 miles. Running ams oil. I have only owned the truck about 7 weeks. When I start the truck I some times get a lifter noise. It sounds like a deisl. It only lasts a few seconds and goes away. It does'nt do this on every start up only some times. Cold or hot doesn't make any differance. What's the deal?
