Started with a #4 misfire and no engine power and dealer said truck was fine. Finally after 4 cylinder misfiring, dealer agreed truck had an issue and is now saying I need a valve job done for # 1800. 00 but it looks like I should tell them that its the lifters. . 74,000 on my 2007 Tahoe for a 25,000. 00 truck not only that but they are saying if that don't fix it then I need to pay 3500. 00 for a cam shaft. Its running but check engine light stays on.
Check engine light came on and I pulled over and there was no oil. It has been using oilever since I bought the vehicle, it will use anywhere from a 1 1/2 to 2 quarts of oil in between oil changes.
