    Ok Update time.. Came home from work today went in the house to check my mail (Got a check coming from someone on here.. ) 15 mins later I say hey lets go check the oil.. dip stick in and out and it says 0!!!! 2 times and nothing on the stick.. :grrrrrr: Went over to the dealership and started talking it's now been 1500 miles since they did the oil change..
    They made me wait 20 mins so they could check it.. And they said Thats it.. It goes in Mon to put the screen or new shield in by the Valves.. Then they top off the oil and we see what happens after a few miles.. If it happens again Rings and pistons.. Not happy.....!!

    Is AFM the same as DOD?? Because they make a DOD delete kit for $400, and you get rid of it forever. It's not just tuning, It involves replacing the valley cover among other things?? Just curious.

    That sucks. How low was it? I know you said that it did not show up on the stick, but how many quarts did it take to show up? I would be concerned that now you not only have a truck burning oil but it now has been driven low on oil. I wonder how the plugs look now? I think that most the reports say that #7 fouls out first.

    Do you have this covered under warranty Enkei?? If not your in for a big surprise, a guy I work with just had his Denali in for the same thing. They replaced pistons and rings, at the tune of $3,000.

    Well.. Got the truck back today in my driveway.. Photo-0435 (2).jpg Here is a list of what they did..

    (1) New Rocker Arm cover # 12570427
    (2) Cleaner # 88861803 My guess is that it's the Carbon Cleaner They told me they Cleaned the whole motor.
    (3) New Oil 5w30 6 Qt's
    (4) Deflector # 12639759 I think they said it is in the Oil pan they did remove it..
    (5) Gasket # 12612350

    So we will see what happens after a few days..
