Now at 99,656 kms. Since the first step in the warranty repair (the drivers side valve cover replacement at 95,424km) it's going in tomorrow, they're going to drop the oil pan and fix/install something to "fix" this. So here's where we're at:
80,100km Oil change, level now at full.
83,666km Add oil warning
86,470km Oil change
89,192km Add oil warning
91,655km Taken to GM for oil change, and reported problem. Start Oil Consumption Test.
95,424km Add oil warning. GM replaces drivers side rocker cover TSB #10-06-01-008C.
99,656km Add oil warning. GM performs service with 'oil pan deflector' (will have more details once I get the TSB tomorrow when they actually DO the service)
Picked up the truck.... there's a new TSB on this. (Yes, again.) 10-06-01-008D which was issued on January 17, 2012.
Anyway, this time they dropped the front diff, dropped the oil pan, and installed a "bell housing" thing on top of a tube that sprays oil within the oil pan. Kinda like an umbrella.. the tube points up, and this steel 'umbrella' goes on top, and keeps the oil from spraying up, redirecting it down. He showed me the pictures that were on the TSB, it makes alot more sense than I can describe it. Anyway, they also cleaned all the pistons and rings.
So here we go lets see if THIS works.
The service at this dealer has been second to none. No hassles, super friendly.
Well update so far... 2500km and not a drop of oil lost so far.... knock on wood...
