I have a 1997 toyota corolla 4 dr. Sedan with 183,604 miles.I had my oil changed a couple of months ago and two weeks later the engine oil light came on.I checked for oil leaks but did not find any oil on the ground.I brought it back to where I had the oil changed and they found whre the oil was leaking from and told me to go to a place that works on foreign cars. When I went there they told me I had to change a few parts and that the oil was leaking worst near the oil pan. They changed the valve cover gasket, oil pan gasket, camshaft seal, timing belt.I went to another place to change my oil and had them look for oil leaks. The said that there was still a oil leak so I brought the car back to the place that worked on it and the owner siad he would make the mechanic redo the work. If that doesn't work I was wondering if there isn't something else wrong with the car it doesn't blow smoke out the exhaust or anything like that.
