Hello all,
Thanks for taking the time to read this/help out if possible.
First thing's first, she has 193k on her but still drives like a dream and just always seems to start up without fail. I've done 45k miles on it in the two and half years I've owned it and usually put in a qt every 1k miles, if that, so it seemed to always do this but not this badly, and previously my gas mileage was 29+. I drive delivery for a place in Syracuse and have used my car doing it for a few months now, putting on an average of 75-90 miles per week for work. Within the past couple weeks I've been going through a half quart of oil or so, per 250-300 miles driven and my gas mileage dropped to 16.8 in the city (with some idling), way below what I would expect.
I don't see it burning anything. No blue, white, or black smoke. I watched it while it idled for 30 mins and saw nothing, had a friend drive it around in front of me accelerating and downshifting and didn't see anything. Plus it passed emissions in March just fine. It has some oil on the engine and the intake manifold is blackened with soot, as is the muffler and the back end of the car immediately near it. I've replaced the PCV valve, made sure it wasn't sucking in coolant and tracked my thermostat guage to make sure it wasn't overheating to try and rule out a headgasket. I put cardboard under it for a couple days while I had class but saw no drips of anything. No loss of power from the engine either, she still runs and drives great. The idle is normal too. I read something about the pistons being undersized for the 99 corolla engine which would cause oil consumption later on, could this be it?
I'm a poor college student and just had to come up with $1500 for first/last/security down on a place for the next two semesters while paying my normal rent this month so I'm kinda drained. Which sucks because I would need to get a compression/dripdown test to get a more accurate representation of the problem but can't for like 2-3 weeks, depending on tips.
So what happens if I keep checking the oil and filling it up when it needs it? Bad idea? Anyone have any idea of the culprit from the described symptoms? How long do you think it'll hold up?
Thanks
