1997 GMC K1500 5.7 L 113000 Miles. When I first start my truck, it makes a loud ticking sound. I'm pretty sure it's coming from the rear of the block, possibly from under the valve cover or back by the distributor. There is a slight loss of power until the truck has run for a few minutes and warms up, then the tick gets quieter until it's unaudible. Sound like a common problem, or is there something I can check to figure out where the problem is?
