Wondering if anyone has had this problem before.I have a vacuum leak that is unknown. I took some starting fluid and sprayed it around the intake-upper and lower and no reaction. There is also a leak on the driver side of the car (oil). It is running down the outside of the exhaust from the number seven cylinder almost all the way down to the cross over (X-pipe). I put some sylicone on the the valve cover gasket and still there is a leak. Just for information, I had my car hooked up to a snap-on solus ($4,000 dollar computer) at my mechanics shop and after he adjusted the timing, The computer is not detecting any other problems. Any infromation would be greatly appreciated.
