So I have an 08 hybrid Tahoe that I love but it started to drink oil like I drink long islands. I know GM has issues with the AFM. It just rolled 104k miles and I really don't want to trade it in for a new car as I don't want payments again. I know there have been TSB's put out with an updated valve cover, some kind of oil deflector, replacing the lifters and piston rings and in come cases they replace the engine. Its out of warranty and I have no problem doing the work, I just don't want to waste time throwing parts at it that wont fix it. Anyone else have any fixes that actually work?
