When I first bought the car about 6 months ago, I needed to change the oil and took it to Pep boys for an oil change. It took me a few months to find this site and read my first oil change. I hit a few big bumps in the road. I don't know if this caused the leak but it showed up a few weeks later. Before I realized the car was leaking, the car made a grinding sound when backing out the first ten feet. It seemed to be related to the clutch and I thought it was a throw out bearing. When I changed the oil (thanks to this site) the filter slid off the shaft of the filter assembly as I pulled it out of the engine. It was a cheap paper filter which I guess had the wrong oil ring I.D. The grinding when I back out has stopped after the oil was changed.

What do you think the grinding was? Do you think I could have damaged the engine?

 

Pep Boys? for an oil change? .... OMG.

Did you or have you checked the oil level when they were done? What brand and weight oil did they use? What filter did they use? Did they put new O-rings on the filter stem? Lastly did they put in 8.5 quarts of whatever they used and how much did they charge you for this?

Frankly, I wouldn't take my Schwinn to Pep Boys.

 

The car lost very little oil. They did everything correct but use a cheap or incorrect filter. I wached them change the oil (0w-40) and install new o-rings. It would be nice to see the cross section of the filter assembly in the engine. The car has low profile tires and you hit a bump in the road, the filter is on a shaft upside down and the force of the bump would push it down the shaft. The grinding noise lasted a few seconds which sounded like you were gringing the gears of the transmittion. If I pushed in the clutch the noise woud disappear. The noise would stop after about ten feet. The oil does drip down in the ac clutch but the air was not on and I don't thank it would make that type of noise. AS I said the noise has stopped after the did the oil change myself.

 

These cars use a scaled down version of an old fashoned "drum style" parking brake system which uses brake shoes instead of pads like a disc brake system does. It makes a lot of noise. Usually most obvious when backing up. I'm guessing that was what you heard.

 

Exactly what I thought when I read the thread title.
Wonder how long it took them to even locate the oil filter!

 

If it's almost like a "POP" sound then it could be .....when the humidity (or after a rain or wash) is high....then after being in the garage all night a thin layer of rust forms on the rotors....as it breaks loose...you can hear a POP.....

Happens a few times a year to my 6 spd as I back out of the garage in the morning.
