Default Help with oil leak?

My car is leaking right behind the water pump/ optic spark/ pulley. I place my hand right under the optic spark and it came out full of oil. Has anyone had this problem? I know is coming from that thing right behind the optic ( I forgot the name of it ) Does any one know what kind of gasket or gaskets I need to buy in order to fix the leak. Any other gastket in theat area that I should change since Im taking out almost everthing infront of the engine?

Front cover seals for the w/p, opti, and front mail seal. Of course you will need new w/p gaskets as well. You sure it is not the front of the intake leaking?

Not sure if is the front of the intake leaking. I have to check tomorrow. I look with a flash light and most of the oil seems to be coming from the bottom right under the optic. Is it easy to change the seal of the intake?

If you discover that it is the intake, double check to see if the bolts are torqued to spec. Mine was leaking a bit from the front and rear of the intake, and I found that the bolts on both ends were not tight. I tightened them all to spec and it hasn't leaked a drop in over 5000 miles.

Good point, I will check the bolts. Now If I need the seals, were can I get them. I've check eckler's and I only see the seals up to 1991.

Here's a great thread on seal replacement, but unfortunately a lot of the pictures have disappeared:

And a thread on replacing the intake gaskets:

I have seen these guys mentioned as a source for the front cover seals - I would imagine they're available from the dealer, too:
