Do you have a cam seal leak, or just a leak in the front part of the head? Usually the factory leak causes most people to think that the cam seal is leaking. The factory leak is near the dist. cap, passenger side front. I seal mine up with Goop Automotive glue (Wal-Mart, in a red tube) after cleaning with starting fluid. Not everyone uses this glue but I have found it to be very durable and flexible under heat, and mine does not leak anymore.

But if you think that the cam seal is leaking, here is how you can change it out:

Once you remove the distributor cap and wires, you will be able to remove the rotor button. Behind the rotor button is what's called the "drive dog" which is bolted to the end of the camshaft...usually a torx head bolt (forget what size at the moment but it's small)...be careful not to strip out the bolt while trying to remove it.

After you remove the drive dog you will have full access to the cam seal, which you can remove with a small cold chisel or screw driver. I always lubricate all of my seals before installation. Hope this helps you.
