Hi everyone I was wondering if anyone has experienced the problem I am having with my 2016 Silverado. It is a 4x4 with 5.3l. The truck is about six months old, and has a little over 4 000 miles on it. The oil level in the truck will rise about 1/2 a inch over the full mark within 150 miles after an oil change. I have been back to the dealer 5 times so far, and they replaced the high pressure fuel pump twice. They cannot seem to figure out what to do next. I am wondering if anyone on here has any suggestions. It also never turns on any lights, and it seems to run fine. Any help would be greatly appreciate. Thanks so much!!
