How many miles on this car? Many more miles than in the following thread of yours? Maybe the previous owner did not look after it too well.
This was a post of yours in January 2015.
Hi
Recently I ran the smog check and the tester told me the car looks like it is new. However, I noticed my exhaust are dark even my bumper is getting dark... I took the freeway almost everyday in a total of 70 miles .. my car is 92k miles and every two weeks I need to replace a quarter of oil at least.
I do not have leakage.. I had one my I changed the gasket by myself and that's fine now..
The question is... this oil reduction is my pistols and valves ? if yes, how the smog test passed without problems?
Many thanks
