Hey I've been checking on this post for a while now and thought I should share my oil issues. I own a 2007 gmc Sierra that I bought used that consumed oil the day I got it. I've been through the PVC valve,valve cover fix, deflector shield,lifters all of witch had no fix. So last month they decided that the problem was the rings so they changed the pistons and rings. I had hope when the service manager told me the oil rings were collapsed from excessive carbon build up. The bad rings were in the cylinders that shut down during afm. Well long story short 3000 miles later low oil light comes on wtf. When I bring it in they said it was only down 1.5 quarts so I ask how they came to that conclusion. Their answer was they refill the truck with oil until its full.I asked them what they considered full,they said the top of the marks on the dipstick. If anyone has been through this and checked their oil after a dealer service you will notice that when they change your it's normally a half inch obove the marks.basically they put 6 quarts and don't bother checking the actuall level. The dealer really didn't know what to say because now the actuall loss was 2.5. After a long talk they have agreed to replace the engine. My last truck was an 02 silver ado with 250k that maybe burnt a half quart at 5000 miles acceptable.they also didn't want to admit the reason booth catalytic converters and 02 sensors were from the oil burning needless to say there getting replaced too. Thanks
