Noticed white colored goo on oil dipstick during oil addition. Dealer indicated a failed head gasket. Solution is to replace the head gasket. Will also replace the valve cover which the dealer indicates is now a better design than the original cover. Dealer estimate is approx. $1200.
The intake manifold gasket may develop an external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
I can't believe that the 07 Suburban oil consumption problem hasn't been mentioned on this site, it is everywhere else. Many 07 Suburbans burn a lot of oil - GM will try to tell you that a quart every 1500 - 2000 is normal - which is just ridiculous.

Had to replace due to excess wear. Suburban not driven hard - these failed prematurely. In addition, repair by replacing just ball joints made 3 times more expensive due to GM design. The upper control arms had to be replaced making the parts very expensive and the labor 3 times more than normal.
