I have been noticing a disappearance of oil from the crankcase for the last 60k miles. I'm positive there are no leaks. I am also not burning blue smoke. I have not noticed any oil in the air filter or the coolant.
I also recently completed a full tune-up which included plugs, wires, cap/rotor, PCV, fuel filter and radiator hoses (upper + lower). In addition, I had the valve cover gasket and accompanying seals replaced.
The consumption is about 1 quart every 1000 miles. The oil light has never come on.
Could this be due to blowby from bad piston rings? Bad valve seals? If so, will this problem get worse over time?
have the same problem?
