Not repaired yet. Just found it. Oil drops on pavement is how it was found.

I have had the same issue, I have changed the valve cover gasket, but still had the same issue, due to bolts stripping out. I have since added thread inserts, and will change the gasket again this morning, since I lose about a quart a week. I now have over 97,000 miles on the car, and drive downtown to Houston everyday, so if I can get this car to make it a few more years, I will try and nurse it along as long as possible. Also, I just pulled the last valve cover gasket I installed and found that it was NOT leaking, since I placed a small amount of silicone on the top and bottom of the gasket, to hold it in place. The gasket remained intact, so I will need to look for another source of the oil leak. My first thought is the rear seal, and or the oil sending unit, but when I stop at a red light in town, I smell burnt oil through the AC vents, so it has to be dripping on the exhaust manifold at some point. That was why I thought it leaked on the rear of the valve cover gasket, which ends up behind the engine, and seemed to be my source of the dripping oil. I have a large puddle of oil every time I leave home and work, so I know it has to be one of the aforementioned issues, unless someone knows one that has not been mentioned.

I noticed oil leaking on the concrete in the parking spot. I took it to my mechanic, he went over it. He told me several gaskets, oil pan, valve cover, front timming chain cover etc. I had all gaskets replaced the hoses replaced. All is well.

My car is leaking from the front valve cover, oil pan, and timing gasket. But not to sure where the main leak is coming from. I'm thinking its from the the front valve cover. I was wondering how much would the repair cost
