Without jack or ramp, I took some pictures of the oil pan with the leak. Could anyone tell me where the leak is? on underview.jpg, you can see there are a lot of oil near the oil plug. I think it is just because the oil plug is the lowest point on oil pan. There are some dots of oil further at the left upper corner on the picture . To me, it is like there was a lot of oil, but mostly just dried up. It seems to me the leak is from upper part of the engine somewhere. The last oil change is 6 weeks ago, so it can not be the old oil left over on the engine. I checked the oil level in morning before starting the car. It is at the high mark. After starting the engine, it goes to the mid between high and low marks, because the oil is spreading inside the engine. Do you think it is a big leak or small leak? The pictures were taken after driving for 30 minutes, then sitting for 1 hour.
What is the correct time to check oil level? A Beforestarting the engine? B After starting it then shuts it off at cold? C After drive for 10 minutes to make it hot?
Background: It is a Honda Civic. I changed oil very 3000 miles with some cheap store charging 14.99. (Could the oil change messged up my oil plug or they did not tight the oil filter enough?) My car bottom hit a rock recently. The oil leak is
1 teaspoon per 10 minutes.
