I have A 1996 Sierra 1500 5.0 litre 2wd with 140k original miles that when cold seems to have a noticible lifter noise . With the engine warmed up the noise tones down but is still audiable especially during acceleration. This issue came up a few years ago and I have changes the oil regularly . I don't use the truck that much but would like the noise to go away. I've tried adding Seafoam to the oil but that didn't seem to help. Any suggestions would be greatly appreciated.
