Chevy tahoe 2009 brining oil fast
My chevy 2009 tahoe is burning oil fast.no leaks no smoke,
just got oil change 2weeks ago checked today and oil is
almost completely gone.ive had seals amd everything g
replaced last few years.but the oil burning faster as of
lately. Vpuld it be the valve stems?
It could be valve guides but that usually causes smoke on startup, you can change valve seals without removing the head. Did they put oil back in? Also check PCV valve if stuck it will suck the engine almost dry and it won't smoke because the cats are hot enough to burn the oil without smoke.
