I was chasing an
oil leak in the same area. Couldn't find it, very frustrating.
I had my car at Lou's Cars in Littleton for some tuning. He has a neat little machine that injects smoke into the engine. Where the smoke comes out is the leak. Took less than 10 minutes to find it. Turned out to be the fuel pump block off plate.
Find a shop that has one of these cool machines. It will cost you a little to find the leak. But it's so quick and easy, it's worth every penny.
