HELP! 2007 Camry defect?

[michaelzee]

So the other day I realized its been 4k since I changed my engine oil. I checked my engine oil and noticed it was @ the first dot (when oil is @ 2nd dot means full on the stick), so I kinda suspected theres a problem. Keep in my mind this is a 2007 v4 LE camry with 15k miles on it. When I took it to the dealer for the oil change and mentioned the problem, they couldnt really diagnose it and said if it happens again, just take it back to them. 3 days after my oil change. After 24 hours of not driving my car, I check my oil again just to see that the oil is below the first dot. WHAT THE HECK! People say its best to check it when the car hasnt run for a while so that the oil sinks down to pan and you get more accurate reading. blah blah. So, long story short, after 3 days of changing my oil, I have lost 3/4s of it. Any solution to this insanity?

Thanks.

You may have a leak. I doubt that it's burning it.

It is best to check the oil after the engine sits for a bit.

It's also possible that they didn't fill the oil completely.

There is no leak. I have monitored it for the past week or so. Also, when I got the car back from the oil change, it was 3/4 full--not completely @ the 2nd dot, but close. 2 days later, after driving only 150 miles total, and sittin 24 hours without a drive, it drops down to 1/4 oil left. Thanks for reply!

How 'warm' was the car when you saw 3/4 after the oil change?

Check your coolant system. Is your coolant system 100% clean? If you have a milky coolant then somehow your oil has managed to got inside your coolant. I am not a mechanic but you might have a reverse problem with what I got. I got coolant into the engine oil. I mean the oil has to go somewhere if it didn't leak. Keep us post it.
By the way, I found out the real reason why coolant got into my engine. The engine header has a crack line so small that you could barely see it with your eyes.

How warm was it?

Not quite sure, but checked the car 1-2 hours after gettin it back from the dealer. But would the temperature matter? I mean I only have 1/4 of my oil left 2 days later.

My coolant system is 100% clean.

Ive been constantly checking and still see no leaks whatsoever.

I knew I should have bought a Honda =P

Possibly there is a problem with the valve seals. You would not notice any smoke from burning say a quart of oil every 4,000 miles.
Keep us posted as to what happens, I'm sure everyone will be interested in it. I know I will.
